Verethragna, known in later Persian as Bahram, is the Zoroastrian yazata of victory and of the smiting of resistance; his name means, quite literally, the breaking or striking-down of defence, the force that overcomes whatever stands in the way. The Avestan hymn dedicated to him, the Bahram Yasht, is one of the most vivid in the collection, for it describes the god appearing to the prophet Zarathustra in ten successive forms, each an image of irresistible power: a strong wind, a bull with golden horns, a white horse, a rutting camel, a fierce boar, a beautiful youth, a swift bird of prey (usually understood as a raptor whose feathers give protection), a wild ram, a fighting buck, and finally an armed warrior with a golden sword.
Through these transformations Verethragna embodies triumphant, aggressive energy in every register of the living world. He grants strength, health, virility and above all victory to those who worship him, and he was especially honoured by warriors and kings. His importance long outlasted the hymn: the name Bahram remained one of the most popular in the Iranian world, borne by kings of the Sasanian dynasty, and the sacred fires of Zoroastrianism of the highest grade are called Atash Bahram, the Victorious Fire, invoking his conquering power. Verethragna is the divine face of the will to overcome, offering the strength to break every obstacle.
