Each stone component bears identification symbols showing how they fit together, just like a bed or book case produced by the Swedish low-cost furniture manufacturer.
The symbols would have indicated to builders how “male” components fitted into “female” joints.
The coded symbols also appear on red and black decorative panels known as “cymatiums”.
“All the cymatiums and several sections of frieze also have inscriptions relating to the roof assembly system,” Massimo Osanna, the director of the archaeology department at Basilicata University, said.
“So far, around a hundred inscribed fragments have been recovered, with masculine ordinal numbers on the cymatiums and feminine ones on the friezes”.
“The characteristics of these inscriptions indicate they date back to around the 6th century BC, which tallies with the architectural evidence suggested by the decoration.”
