Various information about Parameśvara is available from Nīlakaṇṭha's *Āryabhaṭīyabhāṣya* and from later works also. He belonged to the Alattūr village (Sanskritised as *aśvathagrāma*) and that his house was situated on the northern bank of the river Nīlā⁸. The name of his house Vaṭaśśeri (Sanskritised as *vaṭaśreṇi*¹ ) occurs in his name as usual in the Southern India. A meagre information is available about his parents. In his own work it is given that his grandfather was the pupil of Govinda (different from the author of *Mahābhāskarīyabhāṣya* who lived much earlier), the famous author of *Muhūrtaratna*. He came of the Bhṛgugotra and belonged to the Āśvalāyana school.
