Uncovered in the debris of the Treasury were hundreds of clay tablets with inscriptions in Elamite cuneiform. These tablets, originally sundried, were baked in the heat of the immense fire that destroyed the building, so that many were found intact instead of having crumbled to dust long ago. These tablets, written for the most part in Old Persian and its corresponding translations of Elamite and Babylonian, were of great value to the excavators. We learn from them of the presence in Persepolis of skilled workmen from many parts of the empire, of stone-relief and inscription workers from Egypt, goldsmiths from Caria, and ornament makers from Susa. Some tablets also mention the month and year of the reign of either Darius or Xerxes when a particular work was executed and the amount of compensation-either in kind or in money-the workers received. Other tablets bear records of sales, of land deals, of taxes to be paid, or of the amount of money borrowed from the treasury. Finally, some tablets give instructions about how much haoma, the sacred intoxicating drink, could or should be used at a cult service.
