Bahram also appears as wings, or as a bird of prey, in the crowns of the Sasanian kings. This iconography first appears in the crown of Bahram II which also bears the name of the divinity. A similar image is adopted by Peroz (whose name also means 'victorious') as well as by Khosrau Parwez (again, Parwez meaning 'ever-victorious'). Similarly, boar and eagle heads on caps crown the heads of princes. Boar figures are widespread in Sasanian art, appearing in everything from textiles to stucco and in silver ornaments, coins, and seals. Other animal motifs have been found that recall the aspects of Bahram (see the ten forms of Bahram in the Avesta, above). The bird motif on Sasanian-era fire altars are also believed to represent Bahram.
