The many different varieties of Buddhist art often show buddhas and bodhisattvas, as well as depictions of the historical Buddha, known as Gautama Buddha (or Siddhārtha Gautama, Śākyamuni, or Tathāgata).
Especially in Mahayana Buddhism, the main image in a temple or shrine often does not represent the historical Buddha, although the situation is complicated by Buddhist teachings such as trikaya beliefs by which buddhas, including the historical buddha, have different manifestations.
Depictions could be Gautama, or a bodhisattva, guardian, protector, disciple, or saint. Clues to a figure's identity are found in, for example, the physical characteristics of the Buddha, the objects the figure is holding, its mudra (hand gesture), and asana (sitting or standing position of the body).[1] There may be an image in the figure's crown,[2] or the figure could be holding a book, thunderbolt, vase, jewel, or lotus flower or stem.[3]
Mandalas created for Japanese Shingon Buddhism and Tibetan Buddhism can contain hundreds of different figures that may need interpretation.[1][4] In his paper on the mudrās of bodhisattvas, Carl B. Becker, Kyoto University professor, describes the situation:
When the uninitiated observer first confronts the Buddhist pantheon [of Japan], his reaction may border on bewilderment or dismay. Far from the ascetic agnosticism taught by Gautama, Buddha-like deities are available to answer every material or spiritual need. They wear regal robes or deerskins; they sit, stand, or fly; they have their own sūtras, temples, and guardians....[5]
