v1.c15.179

The region now occupied by peoples of this type forms the eastern portion of the wide extent of territory inhabited by Āryan settlers in the earliest historical times—the period of the Rigveda, probably about 1200 B.C. Their oldest literature, which is in a language closely connected with ancient Persian, Greek, and Latin, supplies no certain indication that they still retained the recollection of their former home; and we may reasonably conclude, therefore, that the invasions, which brought them into India, took place at a date considerably earlier.
