which first came into contact with them in that quarter a name for the whole peninsula. Adopted in the form of Indos, the word gave rise to the Greek appellation India as the country of the Indus. It was borrowed by the ancient Persians as Hindu, which is used in the Avesta as a name of the country itself. More accurate is the modern Persian designation Hindustan, "land of the Indus," a name properly applying only to that part of the peninsula which lies between the Himālaya and Vindhya ranges.
