Conclusion — Europe’s Megalithic Masons Were a System

The final synthesis would reject both extremes:

ONE MEGALITHIC PEOPLE
and
EVERY MONUMENT INVENTED IN ISOLATION.

The more powerful model is:

LOCAL GEOLOGY
⊗ LOCAL LABOUR
⊗ SPECIALIST STONE KNOWLEDGE
⊗ RIVER / COASTAL COMMUNICATION
⊗ REPEATED AGGREGATION
→ REGIONAL MONUMENT TRADITIONS

with occasional:

MOBILE CRAFT SPECIALISTS
→ technical transfer
→ apprenticeship
→ local adaptation.

The key historical object is therefore not simply the megalith.

It is the hidden production network behind it:

QUARRY
→ MASON
→ ROUTE
→ LABOUR
→ MONUMENT
→ PLACE MEMORY
→ REUSE.
