The elephant clock was a medieval invention by al-Jazari (1136–1206), consisting of a weight powered water clock in the form of an Asian elephant. The various elements of the clock are in the housing (howdah) on top of the elephant. They were designed to move and make a sound each half hour. In addition to its mechanical innovations, the clock itself is seen as an early example of multiculturalism represented in technology. The elephant represents the Indian and African cultures, the dragon represents Chinese culture, the phoenix represents ancient Egyptian culture, the water work represents ancient Greek culture, and the turban represents Islamic culture.
