From the illustrious Sumati was born Indradyumna: his son was Paramesht́hin: his son was Pratihára, who had a celebrated son, named Pratiharttá: his son was Bhava, who begot Udgítha, who begot Prastára; whose son was Prithu. The son of Prithu was Nakta: his son was Gaya: his son was Nara; whose son was Virát. The valiant son of Virát was Dhímat, who begot Mahánta; whose son was Manasyu; whose son was Twasht́ri: his son was Víraja: his son was Rája: his son was Śatajit, who had a hundred sons, of whom Viswagjyotish was the eldest. Under these princes, Bhárata-varsha (India) was divided into nine portions (to be hereafter particularized); and their descendants successively held possession of the country for seventy-one periods of the aggregate of the four ages (or for the reign of a Manu).
