Banabhatta wrote Harshacharita, one of the greatest master piece in Sanskrit prose. This biography provides valuable information about the period of Harshavardahana. It is written in kavya style.

His second great work, the prose romance Kadambari, is named for the heroine of the novel. The book 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, Bhusanabhatta.
