Excavations in the ancient Mesopotamian city of Kish have revealed an unprecedented administrative archive focused on the management of high-grade timber imports from the Levant. The 'Bureau of Timber-Seasoning' contains dozens of cuneiform tablets that outline standardized protocols for the slow-drying of cedar wood to prevent warping during temple construction. These records detail the precise humidity and airflow conditions required for different species of wood used in royal architectural projects.
The site also features several large subterranean chambers with ventilated brick walls, which archaeologists believe were the actual seasoning vaults described in the tablets. The ledgers track the moisture-content inspections conducted by royal officials, ensuring that only the highest quality wood was used for the doors and ceilings of the city's major shrines. This discovery highlights the advanced understanding of material science and logistics that governed Old Babylonian civil engineering.
