In Iranian mythology, the lion is a symbol of courage and monarchy. It is portrayed standing beside the kings in artifacts and sitting on the graves of knights. Imperial seals were also decorated with carved lions. The lion and sun motif is based largely on astronomical configurations, and the ancient zodiacal sign of the sun in the house of Leo. Lion and sun is a symbol of royalty in Iranian flag and coins. Goddess Anahita was sometimes shown standing on a lion. Lion is also title of the fourth grade of mithraism.
