Jain art refers to religious works of art associated with Jainism. Even though Jainism spread only in some parts of India, it has made a significant contribution to Indian art and architecture. In general Jain art broadly follows the contemporary style of Indian Buddhist and Hindu art, though the iconography, and the functional layout of temple buildings, reflects specific Jain needs. The artists and craftsmen producing most Jain art were probably not themselves Jain, but from local workshops patronized by all religions. This may not have been the case for illustrated manuscripts, where many of the oldest Indian survivals are Jain.
