jajñe śrāvastako rājā śrāvastī yena nirmitā |
śrāvastasya tu dāyādo bṛhadaśvo mahābalaḥ |
bṛhadaśvasutaścāpi kuvalāśva iti smṛtaḥ || 4 ||

Markandeya said, "O king, after the death of Ikshvaku, a highly virtuous king of the name of Sasada, ascending the throne of Ayodhya ruled this earth. And from Sasada was descended Kakutstha of great energy. And Kakutshta had a son of name Anenas. And Anenas had a son named Prithu and Prithu had a son named Viswagaswa and from Viswagaswa sprang Adri and from Adri sprang Yuvanaswa and from Yuvanaswa sprang Sravastha and it was by this Sravastha that the city called Sravasthi was built and from Sravastha was descended Vrihadaswa and from Vrihadaswa sprang Kuvalaswa and Kuvalaswa had twentyone thousand sons and all these sons were fierce and powerful and skilled in learning. And Kuvalaswa excelled his father in every quality. And when the time came, his father Vrihadaswa installed him--the brave and highly virtuous Kuvalaswa--on the throne. And having thus made over the royal dignity to his son, that slayer of foes--king Vrihadaswa of great intelligence--retired into the woods for asceticism."
