White horses in mythology
White horses have a special significance in the mythologies of cultures around the world. They are often associated with the sun chariot, with warrior-heroes, with fertility (in both mare and stallion manifestations), or with an end-of-time saviour, but other interpretations exist as well. Both truly white horses and the more common grey horses, with completely white hair coats, were identified as "white" by various religious and cultural traditions. Portrayal in myth From earliest times, white horses have been mythologised as possessing exceptional properties, transcending the normal world by having wings (e.g. Pegasus from Greek mythology), or having horns (the unicorn). As part of its legendary dimension, the white horse in myth may be depicted with seven heads (Uchaishravas) or eight feet (Sleipnir), sometimes in groups or singly. There are also white horses which are divinatory, who prophesy or warn of danger. As a rare or distinguished symbol, a white horse typically bears the hero- or god-figure in ceremonial roles or in triumph over negative forces. Herodotus reported that white horses were held as sacred animals in the Achaemenid court of Xerxes the Great (ruled 486–465 BC), while in other traditions the reverse happens when it was sacrificed to the gods. In more than one tradition, the white horse carries patron saints or the world saviour in the end times (as in Judaism, Christianity, and Islam), is associated with the sun or sun chariot (Ossetia) or bursts into existence in a fantastic way, emerging from the sea or a lightning bolt. Though some mythologies are stories from earliest beliefs, other tales, though visionary or metaphorical, are found in liturgical sources as part of preserved, on-going traditions (see, for example, "Iranian tradition" below). Mythologies and traditions European Celtic In Welsh mythology, Rhiannon, a mythic figure in the Mabinogion collection of legends, rides a "pale-white" horse. Because of this, she has been linked to the Romano-Celtic fertility horse goddess Epona and other instances of the veneration of horses in early Indo-European culture. In Irish Myth Donn "god of the dead" portrayed as a phantom horseman riding a white horse, is considered an aspect of The Dagda "the great God" also known as "the horseman" and is the origin of the Irish "Loch nEachach" for Loch Neagh. In Irish myth horses are said to be symbols of sovereignty and the sovereignty goddess Macha is associated with them. One of Cúchulainn's chariot-horses was called Liath Macha or "Macha's Grey" The La Tène style hill figure in England, the Uffington White Horse dates back to the Bronze Age and is similar to some Celtic coin horse designs. In Scottish folklore, the kelpie or each uisge, a deadly supernatural water demon in the shape of a horse, is sometimes described as white, though other stories say it is black. Greek In Greek mythology, the white winged horse Pegasus was the son of Poseidon and the gorgon Medusa. Poseidon was also the creator of horses, creating them out of the breaking waves when challenged to make a beautiful
