one of the greatest masters of Sanskrit prose, famed principally for his chronicle, Harṣacarita (“Deeds of Harṣa”), depicting the court and times of the Buddhist emperor Harṣa (reigned c. 606–647) of northern India.

Bāṇa gives some autobiographical account of himself in the early chapters of the Harṣacarita. He was born into an illustrious family of Brahmans; his mother died when he was a small child, and he was raised by his father with loving care. His father died, however, when Bāṇa was 14, and for some years he traveled adventurously, visiting various courts and universities with a colourful group of friends (including his two half brothers by a lower caste woman, a snake doctor, a goldsmith, a gambler, and a musician). At last he returned home and married; then one day he was called to the court of Harṣa. Treated coolly at first by the Emperor, perhaps because of some gossip about his wayward youth, in time he won the Emperor's high regard.

Bāṇa's biography of Harṣa provides valuable information about the period, though with some obvious exaggeration in the Emperor's favour. Written in the ornate kāvya (kavya) style, involving extremely lengthy constructions, elaborate descriptions, and poetic devices, the work has great vitality and a wealth of keenly observed detail. His second great work, the prose romance Kādambarī, describes the affairs of two sets of lovers through a series of incarnations. Both works were left unfinished; the second was completed by the author's son, Bhūṣaṇabhaṭṭa.
