Although the extension of Brāhmanism from the land of the Kurus and Pañchālas to Kosala was comparatively late (p. 117), the Āryan occupation of the country goes back to an earlier period. In the later Vedic literature two kings of Kosala, Hiraṇyanābha and Para Āṭṇāra, probably father and son, seem to be mentioned as performing the horse-sacrifice in celebration of their victories; and, as the former of these appears in the Purāṇic list before the Kali Age, the conquest of Kosala was evidently attributed to the period before the great war.
