Oxford University Press, 2015. — 432 p. — ISBN 978–0–19–022690–9.
Hinduism has two major roots. The more familiar is the religion brought to South Asia in the second millennium BCE by speakers of Aryan or Indo-Iranian languages, a branch of the Indo-European language family. Another, more enigmatic, root is the Indus civilization of the third millennium BCE, which left behind exquisitely carved seals and thousands of short inscriptions in a long-forgotten pictographic script. Discovered in the valley of the Indus River in the early 1920s, the Indus civilization had a population estimated at one million people, in more than 1000 settlements, several of which were cities of some 50,000 inhabitants. With an area of nearly a million square kilometers, the Indus civilization was more extensive than the contemporaneous urban cultures of Mesopotamia and Egypt. Yet, after almost a century of excavation and research the Indus civilization remains little understood. How might we decipher the Indus inscriptions? What language did the Indus people speak? What deities did they worship?
