Discovery and history of excavation

In the next issue, a week later, the British Assyriologist Archibald Sayce was able to point to very similar seals found in Bronze Age levels in Mesopotamia and Iran, giving the first strong indication of their date; confirmations from other archaeologists followed. Systematic excavations began in Mohenjo-daro in 1924–25 with that of K. N. Dikshit, continuing with those of H. Hargreaves (1925–1926), and Ernest J. H. Mackay (1927–1931). By 1931, much of Mohenjo-daro had been excavated, but occasional excavations continued, such as the one led by Mortimer Wheeler, a new director-general of the ASI appointed in 1944, and including Ahmad Hasan Dani.
