Excavations near the ancient city of Girsu in southern Iraq have revealed the residence and workshop of a Sumerian master-architect from the Early Dynastic period. The most striking find within the structure is a collection of intact clay tablets featuring architectural blueprints and site plans for a major temple complex, complete with measurements and structural notes.
The dwelling also contained specialized measuring rods, level indicators, and cuneiform ledgers detailing the allocation of labor and materials for public works. This discovery offers a rare look at the professional lives of the technical elite who designed the monumental ziggurats of ancient Mesopotamia, demonstrating advanced mathematical and engineering skills 4,500 years ago.
