Peshotanu (Avestan Pəšōtanu, Middle Persian Peshyotan, Peshotan) is an eschatological figure of the medieval texts of Zoroastrian tradition, in particular in the apocalyptic Zand-i Wahman yasn.
In these texts, Peshotanu is also one of the Zoroastrian "immortals" (anoshag-ruwan, "of immortal soul"), and the name peshotanu is an allusion to this idea; the Avestan language word literally means "of surrendered (pesh-) body (-tan)", and is also used as a common adjective as a euphemism for "deceased" (also in a derogatory sense of "of forfeited body" in the context of capital offenses).
(Denkard 4.81) In the genealogy of the legendary Kayanians, Peshotanu is the youngest son of Vishtaspa (Wistasp, Goshtasp, the patron of Zoroaster), and brother of Spentodata (Spandadat, Esfandiyar).
[2] In various texts, Peshotanu is portrayed as one of seven "immortal rulers", residing in Kangdez[3] — a mythical "Fort of Kang" that was initially in the other world (at "star level") but invited down to earth where it landed in eastern Turan (Pahlavi Rivāyat 49).
At the fort, Peshotanu and Hvarchithra (Khwarshedchehr), respectively the younger sons of Vishtaspa and Zoroaster, together with their righteous (ahlav) army, await the final battle against Ahriman and his creatures.
