Ruins at Harappa in the Punjab had long been known to the British, who had used its bricks as ballast for railway tracks, when the Archaeological Survey of India began to excavate in 1921 under Daya Ram Sahni, and in 1922 R. D. Banerji started to dig at the mound of Mohenjo-daro in Sindh. Seals with an unknown script and strikingly uniform bricks pointed to an unknown civilisation. In September 1924 the Survey's director John Marshall announced the discovery to the world. The Indus civilisation, older than expected, was shown to be as old as Mesopotamia and Egypt. Its script is still undeciphered.
