Cāvuṁḍarāya wrote the Cāvuṇḍarāya‧purāṇa [i.e.Triṣaṣṭhi‧mahāpuruṣa‧lakṣaṇa‧purāṇam CP] in 978-979 CE at Śravaṇabeḷagoḷa. It retells the stories of the 63 significant personages (mahāpuruṣa/ śalākāpuruṣa) of the jaina doctrine in chapters of differing length. The CP says that the Mahāpurāṇa was first written by Kūcibhaṭṭāraka and Śrīnandimuni, and later retold by Kavi Paramēśvara (Kaviparamēṣṭhi ca.750 CE), Jinasēna and Guṇabhadra. The text occasionally inserts Prakrit gāhās as well as Sanskrit verses from Kaviparameṣṭhi's Mahāpurāṇa (which is no longer extant) and other sources named as ‘Pūrvācāryar’. Thus our author is redacting and paraphrasing from these sources.
