A joint international team of archaeologists has unearthed a subterranean vault in the ruins of ancient Lagash containing the administrative archive of the 'Master of the Royal Armories'. The find consists of over 400 cuneiform tablets dating to the Neo-Sumerian period, providing the first known 'recipes' for advanced bronze metallurgy. These texts specify exact proportions of copper, tin, and arsenic required to create different grades of weaponry, from ritual ceremonial daggers to high-durability spearheads used by infantry.
Beyond metallurgical formulas, the archive contains detailed inventory logs of armor distribution to various city-state garrisons, revealing a highly centralized military supply chain. Dr. Julian Thorne, a Mesopotamian specialist, noted that one tablet even describes the procurement of 'foreign metals' from Meluhha, further cementing the link between Sumerian warfare and distant trade networks. This discovery offers a rare glimpse into the industrial secret-keeping that maintained the power of Mesopotamian dynasties.
