S.N. Roy is the author of 'The Story of Indian Archaeology'

S.N. Roy noted in 'The Story of Indian Archaeology', “Marshall left India three thousand years older than he had found her.” This was because similar, till-then-unidentified seals were found at excavations at Mesopotamian sites. It was then that the world knew not only of a new civilisation, but also of one contemporaneous with Mesopotamia.
