The kingdom of the Cholas, which, like that of the Pāndyas, was unknown to Pānini, was familiar by name to Kātyāyana, and recognized by Asoka as independent. Inasmuch as the great Maurya's authority unquestionably extended to the south of Chitaldūrg in Mysore, and down to at least the fourteenth degree of latitude, the Pennār river probably was the northern Chola frontier in the Maurya age. In later times that frontier on both north and south was much advanced, while, on the contrary, at an intermediate date, it was greatly contracted during the period of Pallava supremacy.
