v1.c7.387

*ĀRYABHAṬA* (b. 476; fl. 499) Āryabhaṭa himself states (*Gaṇitapāda* 1) that he wrote the *Āryabhaṭīya* in Kusumapura (= Pāṭalipura, modern Patna) and that he was twenty-three years old in Kali 3600 (= A.D. 499) (*Kālakriyā* 10). The statement of Nīlakaṇṭha (b. 1443) that he was born in the Āśmakajanapada (on *Gaṇitapāda* 1) probably refers to his predecessor as commentator, Bhāskara (fl. 629). He wrote two works: the *Āryabhaṭīya* influenced particularly South India, his *ārdharātrika* system North-west India, Īrān, and the early ‘Abbāsid caliphate.
