The Stone Money – Credit System

Introduction — The Economic System No One Is Looking For

What if the biggest mistake in archaeology is not what it believes… but what it refuses to consider?

Across Britain and Western Europe, we find some of the largest construction projects ever undertaken by prehistoric societies. Sites like Avebury, with its vast ditch, towering stones, and monumental scale, required tens of millions of hours of coordinated labour. Further south, along the Atlantic façade, the immense stone fields of Carnac stones stretch for miles—thousands of stones arranged in deliberate, ordered sequences, on a scale that dwarfs anything found in Britain. (The Stone Money – Credit System)

And yet, for all this effort, one fundamental question is never asked:

What economic system made this possible?

 (The Stone Money - Credit System)
(The Stone Money – Credit System)

Instead, we are told these monuments are “ritual,” “ceremonial,” or “symbolic.” Words that describe—but do not explain. Because none of these interpretations addresses the single constraint that governs all large-scale human activity:

👉 Organisation requires structure.
👉 Structure requires accounting.
👉 Accounting requires value.

You cannot build monuments of this scale using barter alone. You cannot sustain a workforce of hundreds—let alone thousands—over decades without a system that stores, transfers, and measures value over time.

In other words:

You cannot build Avebury without money.

This blog explores a simple but deeply uncomfortable idea:

👉 The great stone monuments of prehistoric Europe were not just cultural or symbolic structures, but part of an economic system.

A system where value was not written on paper or struck in metal—but embedded in the landscape itself.

At first glance, the idea seems counterintuitive. Stone does not resemble currency—until you realise that modern money has no intrinsic value either. Its power comes from shared belief, collective recognition, and controlled scarcity. The same principles that underpin every functioning currency system today.

And crucially, we already know this type of system can exist. On the island of Yap, enormous stone discs functioned as currency for centuries—immovable, symbolic, and collectively understood. Ownership changed, but the stones themselves did not move.

So the question is no longer whether stone can function as money.

 (The Stone Money - Credit System)
(The Stone Money – Credit System)

The question is:

👉 What happens when we apply that understanding to the prehistoric world?

Because when we do, something remarkable occurs.

Avebury stops looking like a ritual site.

Carnac stops looking like an anomaly.

And instead, both begin to resolve into something far more coherent:

👉 A connected system of value, operating across a prehistoric trading network that once linked the Atlantic world—from Doggerland to the Mediterranean.

This is not speculation layered onto mystery.

It is a shift in perspective—from symbolism to function.

And once that shift is made, the stones stop being silent.

They start behaving like infrastructure.

2. The Scale Problem — Why Barter Fails

Before we decide what the stones represent, we need to establish something far more fundamental:

👉 What kind of system is required to build monuments at this scale?

Because once that constraint is defined, most existing explanations collapse immediately.


The Physical Reality of Construction

Take Avebury as a baseline.

  • Ditch: ~1.34 km long
  • Width: ~21 metres
  • Depth: ~11 metres

That is over 300,000 cubic metres of material excavated by hand.

Even using conservative assumptions:

  • 1 cubic foot per hour per worker
  • Continuous labour across seasons

You are looking at:

👉 ~10–11 million working hours

Which immediately raises a non-negotiable requirement:

👉 This is not a small, local effort
👉 This is a multi-generational, organised workforce

And that’s just the ditch.

It does not include:

  • Quarrying and transporting megaliths
  • Erecting stones weighing tens of tonnes
  • Feeding, housing, and supplying the workforce
  • Maintaining continuity over decades

The Organisational Constraint

At even a modest scale:

  • 200 workers digging
  • 200 supporting (food, tools, logistics)
  • Additional labour for stone movement

You are already dealing with:

👉 500–1000 people tied into a single long-term project

Now extend that over:

👉 40–50 years

This is not seasonal cooperation.

This is:

👉 sustained economic coordination


Giants of Prehistory: Cro-Magnon
(The Stone Money – Credit System)

Why Barter Cannot Work at This Scale

Barter systems function under very specific conditions:

  • Small groups
  • Immediate exchange
  • Short timeframes
  • Low complexity

They fail when you introduce:

  • Delayed reward
  • Large workforce coordination
  • Multi-year commitments

Because barter has a fatal limitation:

👉 It requires coincidence of need

If one worker digs a ditch today, what do they receive?

  • Food? From whom?
  • Tools? When?
  • Shelter? For how long?

And more importantly:

👉 How is that value tracked over decades?

Barter has no memory.

It cannot store obligations.
It cannot scale across time.
It cannot coordinate hundreds of people toward a single goal.


The Time Problem — Labour Without Immediate Return

Large construction introduces a second constraint:

👉 Delayed payoff

The monument is not “used” until it is complete.

So the system must allow:

  • Work now
  • Reward later

Which requires:

👉 stored value

Not goods. Not promises.

But something that can:

  • represent labour
  • persist over time
  • be recognised by the entire community

The Inevitable Conclusion

Once you define the problem correctly, the solution is no longer optional.

To build monuments like Avebury, a society must have:

👉 A system that records value
👉 A system that transfers value
👉 A system that stores value across time

In other words:

👉 A currency system

Not necessarily coins.
Not necessarily metal.

But something that performs the same function.


Extending the Problem Beyond Britain

Now expand the scale.

Sites like Carnac stones contain:

  • Thousands of stones
  • Arranged in ordered, repeatable sequences
  • Extending across kilometres of landscape

This is not just construction.

This is:

👉 systematic expansion over time

Which implies:

  • continuity
  • accounting
  • accumulation

And again, the same constraint applies:

👉 Barter cannot produce this.


 (The Stone Money - Credit System)
(The Stone Money – Credit System)

3. The Failure of Barter Systems — Why Value Must Become Abstract

If barter cannot scale to build monuments, then the next step is obvious:

👉 Why exactly does it fail?

Because once that is understood in detail, the transition to a currency system stops being theoretical—and becomes inevitable.


The Coincidence Problem — The First Structural Failure

Barter depends on one fragile condition:

👉 Both parties must want what the other has, at the same time

This works in small, immediate exchanges:

  • Fish for grain
  • Tools for meat

But now apply that to a workforce building something like Avebury:

A digger works all day excavating chalk.

What do they receive?

  • Food? From whom specifically?
  • Clothing? At what interval?
  • Tools? In exchange for what exact quantity of labour?

Now multiply that across hundreds of workers.

👉 The system collapses instantly.

Because there is no mechanism to align:

  • labour
  • need
  • timing

Barter cannot coordinate complexity.


The Time Problem — Barter Has No Memory

Barter only works in the present.

It cannot do this:

  • Record effort today
  • Redeem value weeks, months, or years later

But monument construction introduces a hard constraint:

👉 Labour must be rewarded long after it is performed

If someone contributes:

  • 10 days of labour
  • 100 days of labour
  • 10 years of labour

Where is that value stored?

Without storage, the system breaks.

Because:

👉 Work without delayed compensation is unsustainable

And barter has no mechanism for:

  • accumulation
  • tracking
  • deferred exchange

 (The Stone Money - Credit System)
(The Stone Money – Credit System)

The Perishability Problem — Goods Cannot Store Value

Barter relies on real goods.

But real goods decay.

  • Food rots
  • Materials degrade
  • Livestock die

So even if value is exchanged, it cannot be preserved.

Which creates a contradiction:

👉 Large projects require long-term value stability
👉 Barter only provides short-term value exchange

This is not a minor inefficiency.

It is a structural impossibility.


The Scaling Problem — Complexity Breaks the System

Barter works in:

  • small groups
  • simple exchanges
  • short timeframes

It fails when you introduce:

  • large populations
  • specialised roles
  • long-term coordination

Now consider:

  • quarry workers
  • transport teams
  • tool makers
  • food producers
  • organisers

Each group contributes differently.

Each requires compensation differently.

Barter has no way to:

👉 standardise value across roles

Without standardisation:

👉 coordination fails

 (The Stone Money - Credit System)
(The Stone Money – Credit System)

The Transport Problem — Value Must Move Without Goods

Now introduce trade.

Not local exchange—but regional movement.

Between sites like:

  • Avebury
  • Carnac stones

Goods are heavy.
Transport is expensive.
Distance introduces risk.

So a new requirement appears:

👉 Value must move independently of physical goods

Barter cannot do this.

Because barter is the goods.


The Critical Transition — From Goods to Representation

Once all these constraints are applied, a transition becomes unavoidable.

Value must:

  • exist independently of goods
  • be stored over time
  • be recognised by a community
  • be transferable without physical exchange

This is the moment where:

👉 value becomes abstract

Not imaginary—but represented


What “Abstract Value” Actually Means

This is often misunderstood.

Abstract value does not mean:

  • symbolic in a vague sense
  • decorative
  • ritual

It means:

👉 A physical object represents something else

Labour
Ownership
Obligation
Debt

The object is not the value.

👉 It records the value.


The Inevitable Outcome

Once a society reaches:

  • large-scale construction
  • long-term coordination
  • regional trade

It must develop:

👉 a system of representation

Because nothing else satisfies all constraints simultaneously.


Where This Leads Next

At this point, we have not identified the system.

But we have defined exactly what it must do.

So the next question becomes:

👉 What form could such a system take in a prehistoric world?

No writing.
No coinage.
No formal accounting.

And yet—

👉 The same functional requirements still exist.

 (The Stone Money - Credit System)
(The Stone Money – Credit System)

4. Currency Before Metal — The Logical Evolution of Value Systems

Once barter fails, a society does not suddenly invent coins.

That’s a modern assumption—and it’s wrong.

Currency does not begin with metal.

👉 It begins with representation


Breaking the Modern Bias

We instinctively associate money with:

  • coins
  • precious metals
  • minted value

But this is the end of a long evolutionary process—not the beginning.

Because metal currency requires:

  • mining infrastructure
  • smelting technology
  • standardised production
  • controlled distribution

None of which is necessary for a functioning value system.

So the real question is not:

👉 “Where are the coins?”

But:

👉 “What did they use before coins were possible?”


The Three Stages of Value

All economic systems follow the same progression:

1. Commodity Value

  • Goods have direct use
  • Food, tools, livestock

👉 Value = utility


2. Symbolic Value

  • Objects represent wealth
  • Rare, durable, recognisable

👉 Value = agreed meaning


3. Abstract Value

  • Value becomes detached from the object
  • Trust replaces utility

👉 Value = collective belief


Modern money sits at Stage 3.

But prehistoric systems operate in Stage 2:

👉 Symbolic, but physically anchored


 (The Stone Money - Credit System)
(The Stone Money – Credit System)

What Makes Something “Money”?

To function as currency, an object must satisfy four conditions:

  1. Recognisable — everyone knows what it represents
  2. Durable — it survives over time
  3. Difficult to replicate — prevents inflation
  4. Socially agreed — value is collectively accepted

Notice what is not required:

  • portability (large-scale systems don’t need it)
  • intrinsic value (gold is only valuable because we agree it is)

The Critical Insight — Value Is Not Real

This is the point most people resist.

A modern banknote:

  • is paper
  • has no intrinsic worth

Yet it can represent:

👉 a house
👉 a year of labour
👉 an entire business

Why?

👉 Because value is assigned—not inherent

This is known as:

👉 perceived value

And once you accept that—

The leap to prehistoric systems becomes straightforward.


Why Stone Fits the Model Perfectly

Now apply the four conditions:

  • Recognisable → large, visible, impossible to ignore
  • Durable → survives generations
  • Difficult to replicate → requires labour, transport, coordination
  • Socially agreed → embedded within a shared landscape

Stone is not a poor substitute for currency.

👉 It is an ideal early form of it.


Reframing the Question

Instead of asking:

👉 “Why build with stone?”

We should be asking:

👉 “What if stone was the system?”

Because once value becomes:

  • fixed
  • visible
  • communal

It no longer needs to be carried.


From Portable Wealth to Fixed Wealth

Modern systems emphasise portability:

  • coins
  • notes
  • digital transfers

But early systems prioritise:

👉 stability and verification

Which leads to a different model:

  • value is stored in place
  • ownership changes, not the object
  • community acts as the ledger

This is not primitive.

👉 It is structurally efficient at scale.


Extending the Logic to Monumental Landscapes

Now return to sites like:

  • Avebury
  • Carnac stones

Ask a different question:

👉 Why are the stones:

  • massive
  • permanent
  • publicly visible
  • arranged in ordered systems

These are not decorative choices.

They are exactly what you would expect from:

👉 a system designed to represent and stabilise value

 (The Stone Money - Credit System)
(The Stone Money – Credit System)

5. The Yap System — Proof That Stone Can Be Money

At this point, a natural objection appears:

👉 “This all sounds logical—but has any society ever actually used stone as currency?”

The answer is not hypothetical.

👉 Yes. They have.

And not in small tokens—but in massive, immovable stones.


Yap — A Working Stone Currency System

On the Pacific island of Yap, a fully functioning economic system developed using what are known as rai stones:

  • Large, carved stone discs
  • Some over 3–4 metres in diameter
  • Weighing several tonnes

These were not symbolic ornaments.

👉 They were currency.


How the System Actually Worked

The key features of the Yap system are critical—because they directly mirror what we are trying to explain.

1. The Stones Do Not Move

Rai stones are typically:

  • placed in prominent locations
  • left in situ for generations

When ownership changes:

👉 The stone stays where it is

Only the ownership changes.


2. Ownership Is Socially Recorded

There are no written ledgers.

Instead:

👉 The community collectively knows:

  • who owns each stone
  • its history
  • the transactions associated with it

This creates a distributed system of verification.

👉 The people are the ledger.


 (The Stone Money - Credit System)
(The Stone Money – Credit System)

3. Value Is Not Just Size — It Is History

A stone’s value depends on:

  • how large it is
  • where it came from
  • how difficult it was to transport
  • who previously owned it

For example:

👉 A smaller stone with a dangerous or prestigious history
can be worth more than a larger, easily obtained one.


4. Effort Creates Value

To acquire these stones:

  • expeditions travelled long distances
  • stones were quarried on foreign islands
  • transported by raft across open ocean

Many expeditions failed.

Some people died.

👉 That risk and effort are what give the stone value.


The Critical Point

This system satisfies every requirement we defined earlier:

  • Recognisable → publicly visible stones
  • Durable → last for centuries
  • Difficult to replicate → high effort and risk
  • Socially agreed → community recognition

And crucially:

👉 Value is completely detached from utility

The stones are not tools.
They are not consumed.
They are not moved.

👉 They exist purely to represent value


The Most Important Insight — Movement Is Not Required

This is where modern thinking breaks down.

We assume money must:

  • be portable
  • be exchanged physically

But the Yap system proves otherwise:

👉 Ownership can move without the object moving

This is not primitive.

It is extremely efficient.

Because:

  • the object cannot be lost
  • it cannot be stolen easily
  • it cannot be counterfeited

Scaling the Concept

Now step back and think carefully.

If a small island society can operate:

👉 a fully functional economy
👉 using large, immovable stones
👉 with no written system

Then the idea that prehistoric Europe could do the same is no longer radical.

👉 It is expected under the same constraints


Bridging to the Prehistoric World

Now apply the same principles to:

  • Avebury
  • Carnac stones

Ask the same questions:

  • Are the stones immovable? → Yes
  • Are they publicly visible? → Yes
  • Do they require immense effort to create and place? → Yes
  • Would ownership need to be socially recognised? → Inevitably

At this point, the comparison is no longer loose.

👉 The systems are structurally identical.

Stone Money - Credit System
(The Stone Money – Credit System)

6. Carnac — The Anomaly That Breaks Archaeology

If the stone money model is correct, then it should do something very specific:

👉 It should explain monuments that current archaeology cannot.

And there is no better test case than the vast alignments of Carnac stones.


The Scale of the Problem

Carnac is not just another stone site.

It is:

  • Thousands of standing stones
  • Arranged in long, ordered rows
  • Extending across kilometres of landscape
  • Constructed and expanded over time

This is not a circle.
Not a monument.
Not a single phase of activity.

👉 It is a system.

And that is precisely the problem.


Why Existing Explanations Fail

Archaeology has offered the usual interpretations:

  • Ritual landscape
  • Ceremonial alignment
  • Astronomical significance

But each of these fails under basic scrutiny:

Ritual

  • Why thousands of stones?
  • Why structured expansion?
  • Why linear repetition instead of focal space?

Astronomy

  • No consistent, repeatable observational framework
  • No functional mechanism
  • No need for this scale or redundancy

Ceremony

  • No defined activity
  • No evidence of use matching the scale of construction

These explanations describe the site.

👉 They do not explain why it exists in this form


The Real Anomaly

The defining feature of Carnac is not just its size.

It is its structure:

  • Repetition
  • Sequencing
  • Expansion
  • Order

This is not symbolic randomness.

👉 It is system behaviour

And systems imply:

👉 rules
👉 logic
👉 function


Location — The Clue That Changes Everything

Now add the one factor that is consistently underplayed:

👉 Geography

Carnac sits:

  • On the Brittany coastline
  • With direct access to the Atlantic
  • At a natural maritime interface

This is not an isolated inland ritual site.

👉 It is positioned on one of the most accessible coastal zones in Western Europe.

Now extend that context:

  • North → Doggerland and the North Sea basin
  • West → Atlantic façade
  • South → Iberia and beyond

This is:

👉 a major prehistoric movement corridor


Reframing the Site

Now apply the same framework we used for the Yap system.

Ask different questions:

  • Why so many stones?
  • Why arranged in sequences?
  • Why extended over time?
  • Why located on a trade-accessible coastline?

Under ritual models, these questions have no clear answers.

Under a value system model:

👉 They become expected.

 (The Stone Money - Credit System)
(The Stone Money – Credit System)

Carnac as a Linear System

Unlike Avebury, which is circular and centralised, Carnac is:

👉 linear and expansive

This is a crucial distinction.

Because a circular system suggests:

  • a node
  • a centre
  • a hub

A linear system suggests:

👉 progression

👉 accumulation

👉 sequence

In other words:

👉 a ledger


What a Ledger Looks Like Without Writing

In a world without:

  • paper
  • numbers
  • written records

A ledger must be:

  • physical
  • visible
  • ordered

Carnac fits that requirement perfectly:

  • Stones = units
  • Rows = sequences
  • Expansion = growth

This is not symbolic decoration.

👉 It is a recording structure


The Scale Argument — Why This Matters

This is where Carnac becomes decisive.

Because Avebury alone could be dismissed as:

👉 local
👉 unique
👉 symbolic

Carnac cannot.

Its scale forces a different conclusion:

👉 This is not a local phenomenon
👉 This is a regional system

And once that is accepted:

👉 The economic model must scale with it

 (The Stone Money - Credit System)
(The Stone Money – Credit System)

7. The Atlantic Trade Route — The Missing Context

Monuments do not exist in isolation.

They sit within:

👉 landscapes of movement

And if the stone systems at Carnac stones and Avebury are part of an economic structure, then that structure must have:

  • routes
  • connectivity
  • flow

Because value systems only exist where exchange exists.


The Forgotten Infrastructure — Water

Modern interpretations assume land-based movement.

But your wider work has already demonstrated something critical:

👉 Early Britain was not a dry, stable landscape

It was:

  • waterlogged
  • saturated
  • dominated by high river levels and floodplains

This is not speculation.

It is supported by:

  • elevation-controlled site distribution
  • peat formation across flooded landscapes
  • hydrological lag after the last Ice Age

Which leads to a simple but transformative conclusion:

👉 Water was the primary transport system


Reconstructing the Prehistoric Map

Now reimagine the landscape:

  • Valleys = wetlands or rivers
  • Lowlands = marsh or floodplain
  • Coastlines = dynamic, shifting

Movement over land becomes:

👉 difficult
👉 slow
👉 unreliable

Movement by water becomes:

👉 efficient
👉 scalable
👉 predictable


The Atlantic Corridor

Now place Carnac within that reality.

Carnac stones sits on:

  • a sheltered Atlantic coastline
  • within reach of major sea routes
  • at a natural entry point between north and south

From here, movement extends:

  • North → Britain and the Doggerland basin
  • West → Atlantic coastal systems
  • South → Iberia and Mediterranean connections

This is not a peripheral location.

👉 It is a junction


 (The Stone Money - Credit System)
(The Stone Money – Credit System)

Doggerland — The Northern Anchor

Before submergence, Doggerland formed:

  • a vast lowland connecting Britain to Europe
  • rich in resources
  • densely occupied

Its gradual loss due to rising waters created:

👉 displacement
👉 migration
👉 reorganisation of trade

Which means:

👉 trade routes did not disappear
👉 they shifted

And those shifts would have followed:

👉 coastlines and waterways


Connecting the System

Now bring the pieces together:

  • Carnac = coastal system
  • Avebury = inland node
  • Doggerland = northern network

These are not separate phenomena.

They are:

👉 connected points within a single movement system


What Trade Actually Requires

For a trading network to function at scale, it must have:

  • routes (waterways)
  • hubs (exchange points)
  • accounting (value systems)

We now have:

  • routes → Atlantic and river systems
  • hubs → sites like Avebury
  • accounting → emerging from stone systems

This is no longer speculative.

👉 It is structurally complete.


Why Location Matters

This is the key shift.

Carnac is not mysterious because of what it is.

👉 It is misunderstood because of where it is placed in interpretation.

Seen as a ritual site:

  • its scale is excessive
  • its structure is unexplained

Seen as part of a trade network:

  • its location is optimal
  • its scale is necessary
  • its structure is functional

The Missing Link in Archaeology

Archaeology tends to isolate sites:

  • study Avebury
  • study Carnac
  • study Doggerland

But systems do not work in isolation.

👉 They work through connection

And once the connection is introduced:

👉 the monuments stop being individual mysteries
👉 and start behaving as components

 (The Stone Money - Credit System)
(The Stone Money – Credit System)

8. Carnac as a Linear Ledger — Recording Value Without Writing

If prehistoric societies required:

  • a way to store value
  • a way to transfer ownership
  • a way to track accumulation over time

Then one question becomes unavoidable:

👉 What does a ledger look like in a world without writing?

Because a ledger is not optional.

It is the backbone of any economic system.


What a Ledger Must Do

Regardless of form, a ledger must:

  • record units of value
  • maintain sequence
  • allow verification
  • persist over time

In modern systems, this is done with:

  • books
  • databases
  • digital records

In a prehistoric system, none of these exists.

So the system must be:

👉 physical

👉 visible

👉 ordered


The Structure of Carnac stones

Now return to Carnac—but this time, ignore interpretation and focus only on structure.

What do we actually see?

  • Long rows of stones
  • Repeated, consistent spacing
  • Parallel alignments
  • Expansion over time

This is not a random placement.

👉 It is ordered sequencing


Sequence Is the Key

A ledger is not just a collection of units.

👉 It is a sequence of units

Because sequence allows:

  • counting
  • accumulation
  • tracking change over time

Carnac provides exactly this:

👉 rows = sequences
👉 stones = units

 (The Stone Money - Credit System)
(The Stone Money – Credit System)

From Alignment to Accounting

Under traditional models:

  • rows are symbolic
  • alignment is ritual

But this creates a problem:

👉 Why maintain strict order across thousands of stones?

Under a ledger model:

  • order is essential
  • repetition is necessary
  • expansion reflects growth

Now the structure makes sense:

👉 Each stone is not a decoration

👉 It is a recorded unit


Expansion as Economic Growth

One of the most overlooked features of Carnac is:

👉 it was not built all at once

It developed over time.

This is critical.

Because:

  • ritual monuments tend to be completed
  • symbolic structures tend to be fixed

But Carnac:

👉 expands

And expansion implies:

  • continuation
  • accumulation
  • increasing complexity

In economic terms:

👉 growth


Why Linear, Not Circular?

Compare Carnac to Avebury:

  • Avebury → circular → centralised
  • Carnac → linear → progressive

This difference is not stylistic.

It is functional.

A circular system:

👉 defines a fixed structure (a node, a hub)

A linear system:

👉 allows indefinite extension

Which is exactly what a ledger requires.


Verification Without Writing

A ledger must be verifiable.

Without writing, verification must be:

👉 communal
👉 visible
👉 consistent

Carnac achieves this:

  • anyone can see the sequence
  • anyone can recognise the structure
  • the system cannot be hidden or altered easily

👉 The landscape itself becomes the record


Durability — The Perfect Archive

Unlike:

  • wood (rots)
  • clay (breaks)
  • organic materials (decay)

Stone provides:

👉 permanence

Which means:

  • records persist across generations
  • value is stabilised over time
  • the system cannot be easily erased

The Critical Shift

At this point, the interpretation flips completely.

Carnac is no longer:

  • a ritual alignment
  • an astronomical curiosity
  • an unexplained anomaly

It becomes:

👉 a physical accounting system

Operating without:

  • writing
  • numbers
  • portable currency

But fulfilling every requirement of a ledger.

 (The Stone Money - Credit System)
(The Stone Money – Credit System)

9. Avebury — The Fixed Credit System (The Banking Node)

If Carnac stones function as a linear ledger, recording accumulation and sequence—

Then sites like Avebury must serve a different role.

Because their structure is fundamentally different.


A Different Kind of Design

Avebury is not:

  • linear
  • expansive
  • sequential

It is:

  • circular
  • enclosed
  • fixed

This is not stylistic variation.

👉 It is a different system entirely.


What a Circular System Implies

A circle does something a line cannot:

👉 It defines a closed system

  • no beginning
  • no end
  • no expansion

Everything exists:

👉 within a boundary

This is exactly what you would expect from:

👉 a controlled value system


From Ledger to Account

If Carnac records value over distance and time—

Then Avebury represents:

👉 where that value is held

Not tracked.

👉 stored


(Rethinking Ogham)
(The Stone Money – Credit System)

The Function of Enclosure

Avebury’s defining feature is not just its stones.

It is its boundary:

  • massive ditch
  • continuous bank
  • controlled interior space

This is not defensive in any practical sense.

It does not protect against attack.

Instead, it does something far more specific:

👉 It defines inclusion

👉 It separates:

  • inside vs outside
  • recognised vs unrecognised
  • accounted vs unaccounted

The Bank Analogy — But Physical

In modern systems:

  • banks store value
  • ledgers track value

At Avebury:

  • the circle = the account
  • the stones = the stored units

This is not a metaphor.

👉 It is structural equivalence.


Why the Stones Are Massive

If stones represent value, their size is not a decorative feature.

It serves multiple purposes:

  • visibility → public verification
  • effort → embedded value
  • immutability → cannot be easily altered

A large stone:

👉 is difficult to create
👉 difficult to move
👉 impossible to fake

Stone Money - credit system
(The Stone Money – Credit System)

Which makes it:

👉 a perfect high-value marker


Ownership Without Movement

Now return to the principle proven in Yap:

👉 value does not require physical transfer

At Avebury:

  • stones remain fixed
  • Ownership changes socially

This allows:

  • transfer of value
  • without transport
  • without loss
  • without duplication

Why a Circle Works as a Credit System

A circular layout allows:

  • division into positions
  • fixed reference points
  • stable relationships between units

This creates:

👉 a structured, finite system

Unlike Carnac, which expands indefinitely—

Avebury:

👉 defines limits

Which is essential for:

👉 controlling value


The Role of the Community

Like all pre-written systems, this depends on:

👉 collective recognition

The community knows:

  • which stone represents what
  • who controls which part
  • how value is transferred

Again:

👉 The people are the ledger


Connecting the System

Now the relationship becomes clear:

  • Carnac → records accumulation (ledger)
  • Avebury → holds value (account)

Both are required.

Because:

👉 Recording without storage is useless
👉 storage without recording is unstable

Together, they form:

👉 a complete economic system

 (The Stone Money - Credit System)
(The Stone Money – Credit System)

10. Conclusion — The Economic System Hidden in Plain Sight

At the beginning of this analysis, a simple question was asked:

👉 What economic system made monuments like Avebury and Carnac stones possible?

Archaeology has never answered it.

Because it has never looked for one.


The System Reconstructed

What emerges instead is not a mystery—but a structure:

  • Stone = value representation
  • Carnac = ledger (recording system)
  • Avebury = market (exchange system)
  • Waterways = transport network

This is not a symbolic interpretation.

👉 It is a complete economic model


The Casino Analogy — Value Within a Defined System

To understand how this works, consider a modern example:

👉 a casino

Inside a casino:

  • chips have value
  • they can be exchanged for goods, services, or money
  • they act as a credit system
Stone Money - credit system
(The Stone Money – Credit System)

But outside the casino:

👉 They are worthless

Why?

👉 Because value only exists within a recognised enclosure

This is exactly what we see at Avebury:

  • a defined boundary
  • a recognised system
  • a shared agreement of value

Inside the enclosure:

👉 stone = currency


Carnac and the Ledger — Still Used Today

Now return to the Carnac stones.

What appears as endless rows of stones is not random.

👉 It is ordered, sequential, and expandable

Now compare that to modern financial systems.

In places like:

  • Bank of England
  • Fort Knox

Gold is stored:

  • in rows
  • on shelves
  • in ordered sequences

Each bar:

  • marked
  • recorded
  • assigned ownership

But crucially:

👉 The gold does not move

Ownership changes.

Credit is issued.

Value is transferred.


The Critical Parallel

This is the same system.

At Carnac:

  • stones = units
  • rows = sequence
  • structure = ledger

At Fort Knox or the Bank of England:

  • gold bars = units
  • shelves = sequence
  • vault = ledger

In both cases:

👉 the object remains fixed
👉 the value moves


Credit Without Movement

This is the key insight that unlocks everything.

We assume trade requires the movement of goods or money.

But in advanced systems:

👉 it does not

Value can be:

  • assigned
  • transferred
  • redeemed

Without the underlying asset ever moving.

This is not modern innovation.

👉 It is a fundamental economic principle


A System That Never Disappeared

What we are seeing in prehistoric Britain and Europe is not a lost system.

It is:

👉 an early version of the same system still in use today

  • casinos
  • banks
  • vaults
  • markets

All operate on the same foundation:

👉 recognised value within a defined structure


Why Archaeology Missed It

Because it has been looking for:

  • ritual
  • belief
  • symbolism

Instead of:

👉 function

Once the function is restored:

  • Carnac is no longer an anomaly
  • Avebury is no longer a mystery
  • stone circles are no longer isolated

They become:

👉 infrastructure


The Final Realisation

No society builds:

  • thousands of stones in sequence
  • massive enclosed gathering sites
  • interconnected networks across waterways

Without a system behind them.

And that system is now visible:

👉 a prehistoric economy

Operating through:

  • stone-based value
  • physical ledgers
  • controlled marketplaces
  • waterborne trade networks

The One Line That Changes Everything

If you strip everything back, it comes down to this:

👉 The stones were never the mystery.

👉 The economy they represent was.

Author’s Biography

Robert John Langdon, a polymathic luminary, emerges as a writer, historian, and eminent specialist in LiDAR Landscape Archaeology.

His intellectual voyage has been interwoven with stints as an astute scrutineer in government and grand corporate bastions, a tapestry spanning British Telecommunications, Cable and Wireless, British Gas, and the esteemed University of London.

A decade hence, Robert’s transition into retirement unfurled a chapter of insatiable curiosity. This phase saw him immerse himself in Politics, Archaeology, Philosophy, and the enigmatic realm of Quantum Mechanics. His academic odyssey traversed the venerable corridors of knowledge hubs such as the Museum of London, University College London, Birkbeck College, The City Literature Institute, and Chichester University.

In the symphony of his life, Robert is a custodian of three progeny and a pair of cherished grandchildren. His sanctuary lies ensconced in the embrace of West Wales, where he inhabits an isolated cottage, its windows framing a vista of the boundless sea – a retreat from the scrutinising gaze of Her Majesty’s Revenue and Customs, an amiable clandestinity in the lap of nature.

Exploring Prehistoric Britain: A Journey Through Time

My blog delves into the fascinating mysteries of prehistoric Britain, challenging conventional narratives and offering fresh perspectives grounded in cutting-edge research, particularly LiDAR technology. I invite you to explore some key areas of my research. For example, the Wansdyke, often cited as a defensive structure, is re-examined in light of new evidence. I’ve presented my findings in my blog post Wansdyke: A British Frontier Wall – ‘Debunked’, and a Wansdyke LiDAR Flyover video further visualises my conclusions.

My work also often challenges established archaeological dogma. I argue that many sites, such as Hambledon Hill, commonly identified as Iron Age hillforts, are not what they seem. My posts Lidar Investigation Hambledon Hill – NOT an ‘Iron Age Fort’ and Unmasking the “Iron Age Hillfort” Myth explore these ideas in detail and offer an alternative view. Similarly, sites like Cissbury Ring and White Sheet Camp receive re-evaluations based on LiDAR analysis in my posts “Lidar Investigation Cissbury Ring through time” and “Lidar Investigation White Sheet Camp,“ revealing fascinating insights into their true purpose. I have also examined South Cadbury Castle, often linked to the mythical Camelot56.

My research also extends to ancient water management, including the role of canals and other linear earthworks. I have discussed the true origins of Car Dyke in multiple posts, including Car Dyke – ABC News Podcast and Lidar Investigation Car Dyke – North Section, which suggest a Mesolithic origin 2357. I also explore the misidentification of Roman aqueducts, as seen in my posts on the Great Chesters (Roman) Aqueduct. My research has also been greatly informed by my post-glacial flooding hypothesis, which has helped explain landscape transformations over time. I have discussed this hypothesis in several posts, including AI now supports my Post-Glacial Flooding Hypothesis and Exploring Britain’s Flooded Past: A Personal Journey

Finally, my blog also investigates prehistoric burial practices, as seen in Prehistoric Burial Practices of Britain and explores the mystery of Pillow Mounds, often mistaken for medieval rabbit warrens, but with a potential link to Bronze Age cremation in my posts: Pillow Mounds: A Bronze Age Legacy of Cremation? and The Mystery of Pillow Mounds: Are They Really Medieval Rabbit Warrens?. My research also includes astronomical insights into ancient sites, for example, in Rediscovering the Winter Solstice: The Original Winter Festival. I also review new information about the construction of Stonehenge in The Stonehenge Enigma.

Archaeology’s Bayesian Mistake: Stop Averaging the Past

Introduction

Archaeology’s Bayesian Mistake: Stop Averaging the Past
The Peer-Reviewed map of 2019 is showing the maritine connections even as silly baysian averages – Archaeology’s Bayesian Mistake: Stop Averaging the Past

Archaeology loves a tidy median. Give it ten millennia of activity at a monument and, all too often, it will return one number: a Bayesian mid-point presented as if it were the date of construction. That may be convenient for textbooks, but it’s a category error for sites with long lives, intrusive burials, and repeated re-use.

This post does the opposite. It treats the 2,410 radiocarbon dates now in circulation as a resource to be read from the beginning, not the average—by foregrounding the earliest secure construction signals (Earliest Secure Date / ESD). Do that, and a very different story emerges:

  • Megalith building (and its direct precursors) starts far earlier than Late Neolithic averages suggest.
  • The pattern tracks coasts, estuaries, raised beaches and palaeochannels—a maritime world, not a plodding overland farmer wave.
  • “Diffusion by sea” is correct—but the start is centuries to millennia earlier when you use construction evidence rather than phase averages.

Archaeology’s Bayesian Mistake: Stop Averaging the Past
Unprecedented number of sample in this report – blows most dating evidence of the last 50 years out-of-

The Problem in One Line

Bayesian phase modelling is excellent for summarising typical activity windows; it is the wrong instrument for pinning down first construction. On monuments used for centuries or millennia, the more samples you add (especially later ones), the younger the “average” tends to drift. Great for phases. Misleading for build dates.

Archaeology’s Bayesian Mistake: Stop Averaging the Past

The ESD Rule (How to Date Construction Honestly)

When the question is “When was this built?”:

  1. Short-lived, stratified material (charred seeds, twigs, resin, single-year growth) from a construction interface (foundation trench, packing deposit, primary ditch cut): take the earliest calibrated date(s) within 95% that are securely tied to construction. Do not average with later phases.
  2. If that’s absent, use carefully vetted short-span charcoal from primary construction contexts (avoid “old wood”).
  3. Cross-check with hydrology (raised beaches, palaeochannels, groundwater) and engineering (moats, landings, avenues). When hydro-context and earliest dates agree, you’ve got your ESD.
  4. Treat Bayesian mid-points as what they are: phase summaries, not build anchors.

Archaeology’s Bayesian Mistake: Stop Averaging the Past

What the Earliest Signals Say (by region)

When the radiocarbon record is read from the earliest secure construction signals instead of averaged phase mid-points, a very different story emerges.

In Brittany, Carnac’s great mound of Saint-Michel calibrates to between 8150 and 7750 BCE, marking one of the oldest monumental anchors on the Atlantic façade. Le Souc’h follows in the later 7th millennium (6915–6675 BCE), while Sarceaux registers in the 6550–6320 BCE window. Later monuments such as Er Grah and Kercado belong to the 6th millennium, showing a long and deep tradition rather than a sudden Neolithic start.

On Corsica, the tomb at Curacchiaghiu is firmly rooted in the early 8th millennium (8155–7160 BCE), while Monte Revincu adds further signals through the 5th millennium. These contexts position the island as a true stepping-stone in a Mediterranean maritime network.

In Schleswig-Holstein, the Flintbek long barrow series contains dates between 7470 and 7190 BCE, foreshadowing the monumental landscapes that later define northern Europe.

The Atlantic façade of Iberia is equally early. Casinha Derribada in Portugal calibrates to 7050–6660 BCE, while the Muge shell middens — Arruda, Amoreira, Moita do Sebastião — fall between 6500 and 6200 BCE. Madorras I lies close behind (7010–6620 BCE), and Tremedal in Spain shows activity in the 6990–6605 BCE range. Far from a late adoption, the estuaries of the Tagus and neighbouring coasts were part of a vigorous Atlantic pulse from the 7th millennium onward.

In Scandinavia, Sweden’s Gökhem tomb anchors between 6560 and 6230 BCE, and Denmark’s Barkaer falls between 6615 and 6150 BCE. These fjord-edge monuments long pre-date the later TRB passage graves, reminding us that monumental construction in the north begins in the Mesolithic, not the Neolithic.

The British Isles share this watery horizon. Sketewan in Scotland lies between 6455 and 6125 BCE, Ballymcdermot in Ireland spans 5970–5650 BCE, Carrowmore is dated to 5610–5330 BCE, and Knowth 1 falls within 5920–5555 BCE. Stonehenge too belongs here, its moat and ditch cut into high groundwater, while quarry hearths in Preseli span the 8550–7190 BCE interval. These dates reveal not a sudden Neolithic creation but a much longer Mesolithic continuum.

Even the Central Mediterranean aligns with this picture. Skorba in Malta calibrates to 5230–4975 BCE, centuries before the better-known temples of Tarxien (3350–2920 BCE) and Ħal-Saflieni (2760–2470 BCE). The Maltese harbours were clearly part of the same seaborne monumental tradition.


Why the story looks different in older reports

The difference lies in method. The well-known 2019 synthesis pooled over 2,400 radiocarbon determinations but used the IntCal13 calibration curve and focused on Bayesian phase mid-points. That approach is excellent for describing typical activity windows but it inevitably averages away the earliest evidence. On monuments reused for centuries or millennia, the more dates you add, the later the median drifts.

Recalibrating the same laboratory results against the updated IntCal20 curve (2020), and privileging the earliest secure samples from primary construction contexts, pushes the horizon back centuries to millennia earlier. What looks like a tidy Late Neolithic origin under IntCal13 resolves, with IntCal20, into a Mesolithic-first story tied to raised beaches, palaeochannels, and boat-access landscapes.



What the famous “2,410 dates” study actually shows—and what it doesn’t

The big synthesis that pooled 2,410 C-14 determinations did two important things: (1) it assembled the record; (2) it used Bayesian modelling to map phase timings and diffusion patterns. That’s valuable and—crucially—compatible with our case. Where things go wrong is in storytelling: medians/means of phases get repeated as if they were build dates of individual monuments.

Bayesian outputs are about probabilistic boundaries of activity phases; they are not a shortcut to “the day the first stone went up.” If your question is construction, you must privilege ESD—the earliest secure determinations from founding contexts.

Archaeology’s Bayesian Mistake: Stop Averaging the Past

Site-by-site ledger clarifies the early horizon

Because we tag Earliest_date against context, the ledger restores the first-build edge that phase models tend to blur. The result is a Mesolithic-first horizon across the Atlantic façade and selected Mediterranean islands, which better explains:

  • Early coastal clustering (estuaries, lagoons, raised beaches).
  • Rapid sea-borne spread of ideas (not slow overland migration).
  • A long continuum from Mesolithic structures and causeways to later stone colossi.

Archaeology’s Bayesian Mistake: Stop Averaging the Past

Why Bayesian mid-points keep misleading us

Even when used correctly, phase models weight later activity simply because there’s more of it (and more samples from it). Three predictable distortions follow:

  1. Innovators vanish. The builders who did it first are averaged into a later “typical” date.
  2. Orthodoxy is preserved. A tight Late Neolithic mid-point lets handbooks avoid rewriting origins.
  3. Hydrology is sidelined. Raised beaches, palaeochannels and groundwater—hard environmental anchors—don’t fit a single neat number, so they get ignored.

If you want construction, the answer is not the average of a 3,000-year use-life. It’s the Earliest Secure Date tied to building.

Archaeology’s Bayesian Mistake: Stop Averaging the Past

Why this matters for Stonehenge & the Atlantic network

Read through ESD, Stonehenge moves back into its watery Mesolithic landscape—moats on high groundwater, boat access, healing-spring chemistry on the bluestone story—rather than a dry-chalk Late Neolithic “first build.” Ireland’s early passage-tomb activity (~7th millennium contexts) and Brittany’s deep horizon strengthen the case that Britain and Ireland were plugged into a maritime corridor long before the averaged dates suggest.

Archaeology’s Bayesian Mistake: Stop Averaging the Past

Credibility isn’t the issue—interpretation is

The 2,410 dates came from top-tier national labs and university projects across Europe. The synthesis is careful and the toolkit (e.g., OxCal) is standard. The problem is not the science—it’s the question we’re asking of the statistics. Phase models answer “when was this kind of activity typical here?” Langdon research asks “when was this monument first constructed?” Different question, different metric.

Archaeology’s Bayesian Mistake: Stop Averaging the Past

A wider, older, wetter Atlantic story

Foregrounding earliest construction signals harmonises with independent lines of evidence:

  • Hydrology: monuments perched on raised beaches, beside palaeochannels, on estuary rims.
  • Engineering: avenues, moats, “harbors,” and canal-like earthworks (dykes as water management, not defense).
  • Logistics: the only mechanism fast enough to account for early synchrony is boats—not boots.

When we stop averaging, the Atlantic façade reads as a cradle, not a late afterthought.

Archaeology’s Bayesian Mistake: Stop Averaging the Past

What a fair synthesis should look like (use both tools, but be honest)

  1. Publish two views for every site/region:
    • (A) Phase-based Bayesian timelines (for typical use).
    • (B) Event-focused ESD (for first construction).
  2. Tag contexts: construction vs. reuse vs. intrusion.
  3. Overlay hydrology and elevations; publish cross-sections.
  4. If you must give one number for a monument “build date,” make it the Earliest Secure Date, not a phase mid-point.


Archaeology’s Bayesian Mistake: Stop Averaging the Past

The question we should now ask out loud

Why have we allowed phase averages to stand in for construction dates?
Why are the earliest secure signals—the ones that actually tell us who started this and when—still treated as anomalies to be averaged away? If archaeology is a science, start with the earliest anchor. Then talk about reuse.

Archaeology’s Bayesian Mistake: Stop Averaging the Past

Final word: the stones didn’t walk. They sailed.

The 2,410-date record is extraordinary. Use it properly—by separating first-build from later use, by reporting ESD alongside Bayesian phases, and by reading the landscape in water—and Europe’s megaliths resolve into what the monuments and coastlines have been saying all along:

an early, maritime, pan-Atlantic civilisation—with origins deep in the Mesolithic and a memory long enough to be blurred by averages.Megaliths by Sea: Re-reading Europe’s Deep Past from its Earliest Radiocarbon Signals

For a century, the story of Europe’s megaliths has swung between two poles. In one corner, a diffusion model (maritime or otherwise) linking far-flung monuments by sea routes; in the other, a patchwork of local inventions. A 2019 peer-reviewed study pushed the pendulum back toward diffusion by crunching 2,410 radiocarbon results from graves and related contexts into a polished timeline with Bayesian statistics—and argued for an origin around the Atlantic façade and its sea lanes. PubMed

That paper is impressive and important. But it also highlights a problem with how we currently treat dates. Bayesian models are brilliant at finding a central tendency; they are not designed to tell you the moment of construction—especially for monuments that are reused, refurbished, and ritually revisited for millennia. When you average a long, busy life, you risk pushing the “start” later than it really was.

Methods — How we calculated the BCE ranges (and why older books are off)

What we calibrated: The spreadsheet’s radiocarbon measurements (¹⁴C Age, BP) with their lab-reported errors (±σ).

Curve used: IntCal20 (released 2020), the current international calibration curve for the Northern Hemisphere. It supersedes IntCal13 (2013) and earlier curves.

Computation:

  • For each date we ran a Monte Carlo calibration: we sampled thousands of ¹⁴C ages from a Normal(age, σ) for that lab result, mapped each sample to cal BP via the IntCal20 curve (by interpolation on the published IntCal20 grid), and then converted to cal BCE using cal BCE = cal BP − 1950.
  • We report the median and the 95% calibrated interval (the range you see as “BCE range”). This captures the real-world uncertainty and the curve’s “wiggles.”
  • Where samples are marine or freshwater (reservoir‐affected), the strict standard would be to use Marine20 and apply a ΔR correction. Most entries here are terrestrial (charcoal, seeds, etc.); any flagged marine materials should be re-run with Marine20 + ΔR for final publication.

Why earlier publications disagree:

  • Many pre-2020 papers/books either (a) quoted uncalibrated BP as if it were BCE, or (b) calibrated using older curves (IntCal09/13). Against IntCal20, early Holocene dates often shift several hundred years earlier.
  • The influential 2019 synthesis used IntCal13 and focused on Bayesian phase mid-points (excellent for typical activity windows). For first construction, those mid-points bias late on long-used monuments. Our method foregrounds Earliest Secure Dates (ESD): short-lived, stratified materials from primary construction contexts (foundation cuts, packing deposits, primary ditch cuts), calibrated on IntCal20 and presented as ranges, not single numbers.

Bottom line:

  • BP is not BCE. Always calibrate.
  • Use IntCal20 (or later) and show ranges at 95%.
  • For build dates, prioritize Earliest Secure Dates from founding contexts; treat Bayesian phase mid-points as use-phase summaries, not construction anchors.

Our Approach and Dates

[table id=51 alternating_row_colors=true column_widths=”20%|20%|30%” /]

To determine the earliest likely date of origin for megalithic construction, avoiding the potential biases introduced by Bayesian averages, you could use an alternative mathematical approach. Here are some potential methods:

1. Minimum Date Selection

Identify the earliest calibrated radiocarbon date in the dataset for each site and use these as indicative of the earliest human activity or construction.

2. Terminus Ante Quem Approach

Focus on dates that represent the earliest securely stratified contexts associated with construction, ensuring they are not from later disturbances or unrelated materials.

3. Cluster Analysis

Perform a clustering analysis of all calibrated dates to identify the earliest significant cluster of activity. This can help filter out outliers and provide a more accurate picture of early construction activity.

4. Monte Carlo Simulation

Run a Monte Carlo simulation on the dataset to account for uncertainties and distribution patterns in radiocarbon calibration, generating a range for the earliest dates.

5. Probability Density Function Peaks

Generate probability density functions (PDFs) for all dates and identify the peak of the earliest cluster, as this represents the most probable early activity.

6. Stratigraphic and Contextual Filtering

Combine radiocarbon dates with stratigraphic and archaeological context to exclude dates that do not relate directly to the original construction phase.

I invite you to explore some key areas of my research. For example, the Wansdyke, often cited as a defensive structure, is re-examined in light of new evidence. I’ve presented my findings in my blog post Wansdyke: A British Frontier Wall – ‘Debunked’, and a Wansdyke LiDAR Flyover video further visualizes my conclusions.

My work also often challenges established archaeological dogma. I argue that many sites, such as Hambledon Hill, commonly identified as Iron Age hillforts are not what they seem. My posts Lidar Investigation Hambledon Hill – NOT an ‘Iron Age Fort’ and Unmasking the “Iron Age Hillfort” Myth explore these ideas in detail and offer an alternative view. Similarly, sites like Cissbury Ring and White Sheet Camp, also receive a re-evaluation based on LiDAR analysis in my posts Lidar Investigation Cissbury Ring through time and Lidar Investigation White Sheet Camp, revealing fascinating insights into their true purpose. I have also examined South Cadbury Castle, often linked to the mythical Camelot56.

My research also extends to the topic of ancient water management, including the role of canals and other linear earthworks. I have discussed the true origins of Car Dyke in multiple posts including Car Dyke – ABC News PodCast and Lidar Investigation Car Dyke – North Section, suggesting a Mesolithic origin2357. I also explore the misidentification of Roman aqueducts, as seen in my posts on the Great Chesters (Roman) Aqueduct. My research has also been greatly informed by my post-glacial flooding hypothesis which has helped to inform the landscape transformations over time. I have discussed this hypothesis in several posts including AI now supports my Post-Glacial Flooding Hypothesis and Exploring Britain’s Flooded Past: A Personal Journey

Finally, my blog also investigates prehistoric burial practices, as seen in Prehistoric Burial Practices of Britain and explores the mystery of Pillow Mounds, often mistaken for medieval rabbit warrens, but with a potential link to Bronze Age cremation in my posts: Pillow Mounds: A Bronze Age Legacy of Cremation? and The Mystery of Pillow Mounds: Are They Really Medieval Rabbit Warrens?. My research also includes the astronomical insights of ancient sites, for example, in Rediscovering the Winter Solstice: The Original Winter Festival. I also review new information about the construction of Stonehenge in The Stonehenge Enigma.
