Brihatkatha

Bṛhatkathā (बृहत्कथा) (Sanskrit, "the Great Narrative") is an ancient Indian epic, said to have been written by Guṇāḍhya (गुणाढ्य) in a poorly-understood language known as Paiśācī. The work no longer exists but several later adaptations — the Kathāsaritsāgara (कथासरित्सागर), Bṛhatkathāmañjarī (बृहत्कथामंजरी) and Bṛhatkathāślokasaṃgraha (बृहत्कथाश्लोकसंग्रह) in Sanskrit, as well as the Peruṅkatai and Vasudevahiṃḍi in vernaculars — make commentary on the piece.

The date of its composition is uncertain. According to testimonials by later Sanskrit poets such as Daṇḍin, the author of the Kavyadarsha, Subandhu, the author of Vasavadatta, and Bāṇabhaṭṭa, the author of the Kadambari, the Bṛhatkathā existed in the 6th century CE. According to other estimates it predates that period by several more centuries. For example, if the story of Udayana by poet Bhāsa (and also later by Harsha in Ratnavali) was inspired by Brihatkatha, it had to be older than the time of Bhāsa — itself uncertain, but before the 3rd century CE.
