The representation of "khwarrah" as a ram reappears on Sassanid seals and as an ornament in Sassanid architecture. "Khwarrah" also appears in Sassanian crowns as a bird with a pearl in its beak. Depictions of "khwarrah" as a bird are allusions to the Avestan myth of "Yasht" 19.35-36, 19.82 in which "khvarenah" takes the shape of a bird as it leaves Yima (MP: Jamshid), a metamorphosis similar to that of the yazata of victory, Verethragna. The crown as a repository of "khwarrah" is also attested in the Paikuli inscription of Narseh, which describes the punishment meted out to an individual who has been "driven by Ahriman and the "dev"s" to steal "khwarrah" by placing the crown on the head of a false ruler. Another ubiquitous motif in Sassanian art is the symbol of a boar, which is a representation of the protection of the "yazata" Verethragna (MP: Wahram) given to rulers that hold "khwarrah".
