Ancient India is a collection of personal accounts written by Megasthenes and Arrian. This is a classic text on the ancient geography of India translated in English by John W. McCrindle. The account of India written by Megasthenes from his personal knowledge of the country is justly held to be almost invaluable for the light which it throws upon the obscurity of early Indian history. A translation of the first part of the Indika of Arrian has been subjoined, both because it gives in a connected form a general description of India, and because that description was based chiefly on the work of Megasthenes.

John W. McCrindle was a Scottish classical philologist and educator who wrote several major works on references to India in ancient classical writings. He taught at Patna College and later at Krishnagar College.
