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.
