Kathasaritsagara
The Kathāsaritsāgara ("Ocean of the Streams of Stories") (Devanagari: कथासरित्सागर) is a famous 11th-century collection of Indian legends and folk tales as retold in Sanskrit by the Shaivite Somadeva from Kashmir. Kathāsaritsāgara contains multiple layers of story within a story and is said to have been adopted from Guṇāḍhya's Bṛhatkathā ("the Great Narrative"), which was written in a poorly-understood language known as Paiśāchī.
