Kanthaka (in Pali and Sanskrit) (6th century BC, in Bihar and Uttar Pradesh, India) was a favourite white horse of length eighteen cubits that was a royal servant of Prince Siddhartha, who later became Gautama Buddha. Siddhartha used Kanthaka in all major events described in Buddhist texts prior to his renunciation of the world. Following the departure of Siddhartha, Kanthaka died of a broken heart.
