According to the tradition as we find it recorded in the inscription of Kakustha Varman, it was a Brahman by name Mayura-Sarman who went to complete his Vedic studies to the "Brahman settlement," (Ghatika) of Kanchi. There he got into a quarrel with either some cavalry men, or an important officer of the cavalry of the Pallavas, and gave up the life of a Brahman and assumed that of a warrior. He was so successful in his new life when he acquired possession of all the forest country up to Sri Parvata, laid the great Bana under contribution, and otherwise made himself a very considerable obstacle to the pretensions of the Pallavas who were just then rising into importance. The Pallava monarch for the time being considered it prudent to recognise the redoubtable Brahman as a military officer of his with the government of a considerable province extending from the sea in the west to the eastern limit of "Prehara."1 Who were the Pallavas to appoint this Brahman to the Governorship of the province whose capital was Banavase? The Pallavas must have possessed the territory which the Brahman perhaps made his own, and then the Pallavas rightfully conferred it upon the Brahman as his fief. If it had not been so, there is no sense in a Kadamba inscription claiming this as the rightful foundation of their title to the province. It seems therefore that the alliance between the Naga and the Pallava which gave the title to the Pallava for the possession of the whole of the territory means nothing more than an alliance between the Pallavas and the Cutus. This alliance resulted in the Pallavas becoming ultimately rulers not only of the Pallava territory proper but of practically the whole Empire of the Andhras, as much of it at any rate as had not gone into the possession of others like the Abhiras and the Ikshvakus of the east. This assumption would satisfactorily explain the setting up of the Kadamba power in the region which was peculiarly the province of the Cutus. If that should turn out to be so, the statement regarding Skandasishya that he took from Satyasena the ghatika of the Brahmans would become not merely possible but very likely. It is perhaps a subsidiary branch of this family of the Cutus that ultimately overthrew the Kadambas in this region, and founded the dynasty of the Chalukyas.
