A groundbreaking study using 3D LiDAR scans and Artificial Intelligence has revealed a 'temporal signature' in the quarrying of Baalbek’s massive stone blocks. The AI analysis identified microscopic tool marks that suggest a highly synchronized cessation of work across the quarry, challenging previous theories about a gradual decline in construction activity.
The research confirmed that while the temples show standard Roman iron chisel marks, the unfinished 1,650-ton blocks feature distinct engineering signatures. This suggests the project was part of an immense industrial-scale operation that was suddenly halted, providing new insights into the logistical limits of ancient builders.
