A Jaina of the Nāgendragaccha, Udayaprabha was the pupil of Vijayasena (died 1245; see B. J. Sandesara [1953] 69-70), the pupil of Haribhadra, the pupil of Ānanda and Amaracandra who were contemporaries of Jayasiṃha Siddharāja (fl. ca. 1093-1143) and pupils of Śāntisūri, the pupil of Mahendraprabhu (see BORI 1886/92, pp. xiii-xiv) and a member of the literary circle of Vastupāla (died 1 January 1240) who was minister from 1220 to the Vāghelas Lavaṇaprasāda and Vīradhavala (died 1238). Udayaprabha wrote many poems, praśastis, and commentaries between 1221 and 1243; the details are given in B. J. Sandesara [1953] 71-72 et passim. Two of his praśastis of Vastupāla can be found in Sukṛtakīrtikallolinīyādi Vastupālapraśasti-saṅgraha, SJS 5, 1961, pp. 1-20; his Dharmābhyudaya is edited in SJS 4, Bombay 1949. His work on astrology is entitled Ārambhasiddhi = Pañcavimarśa in 412 verses and 5 chapters. Aside from anonymous commentaries, an avacūrṇi was written by Samayaratna Gaṇi and a vārttika by Hemahaṃsa Gaṇi (fl. 1458). Manuscripts:
