Kinnara
A kinnara is a paradigmatic lover, a celestial musician, half-human and half-horse (India) or half-bird (south-east Asia). Their character is clarified in the Adi parva of the Mahabharata
Kinnaras are one of the exotic tribes of Ancient India mentioned along with Devas , the word Kinnara is related to the word Kimpurusha (meaning "what man?" i.e. hermaphrodite, half man-half woman). Legends have it that the original Kinnaras were the troops of Ila, the unfortunate King who was transformed into a woman by means of a curse. Later he/she became a wife of the divine hermit and god of the planet Mercury, Budha, while his former soldiers were turned into kinnara by the hermit Budha.
The epic Mahabharata mentions Kinnaras, not as horse-headed beings but as beings who were half-man and half-horse i.e. like a Centaur. Mahabharata and the Puranas describe regions north to Himalayas as the abode of Kinnaras. Another reference in the epic considers them as a sub-group of Gandharvas.
The Kinnari, (usually spelt 'Kinnaree' as noted below) in Thai literature originates from India, but was modified to fit in with the Thai way of thinking. The Thai Kinnari is depicted as a young woman wearing an angel-like costume. The lower part of the body is similar to a bird, and should enable her to fly between the human and the mystical worlds.
