Archaeologists excavating a residential district in the ancient Mesopotamian city of Larsa have discovered a unique archive of cuneiform tablets detailing the legal framework for professional apprenticeship. Dating to approximately 1800 BCE, these records outline strict contractual obligations for master merchants and their students, including provisions for housing, food rations, and the transfer of specialized trade secrets regarding metalwork and textile exports.
The archive, found in the ruins of a private villa, includes several 'graduation' certificates that granted apprentices the right to open their own trade houses. These documents reveal a highly regulated urban labor market where social mobility was tied to certified skills. The find is a major contribution to the study of ancient economic history, showing that Babylonian society utilized formal legal protections to ensure the continuity of its mercantile expertise.
