In Persian mythology, the Peri (Persian: پری pari) are descended from fallen angels who have been denied paradise until they have done penance. In earlier sources they are described as agents of evil; later, they are benevolent. They are exquisite, winged, fairy-like creatures ranking between angels and evil spirits. They sometimes visit the realm of mortals.
In Persian mythology and literature
At the start of Ferdowsi's epic poem Shahnameh, "The Book of Kings", the divinity Sorush appears in the form of a peri to warn Keyumars (the mythological first man and shah of the world) and his son Siamak of the threats posed by the destructive Ahriman. Peris also form part of the mythological army that Kaiumers eventually draws up to defeat Ahriman and his demonic son. In the Rostam and Sohrab section of the poem, Rostam's paramour, the princess Tahmina, is referred to as "peri-faced". Peris were the target of a lower level of evil beings called دیوسان divs (دَيۋَ daeva), who persecuted them by locking them in iron cages. This persecution was brought about by, as the divs perceived it, the peris' lack of sufficient self-esteem to join the rebellion against perversion.
