Vishtaspa ( ; ; ; ) is the Avestan-language name of a figure of Zoroastrian scripture and tradition, portrayed as an early follower of Zoroaster, and his patron, and instrumental in the diffusion of the prophet's message. Although Vishtaspa is not epigraphically attested, he is – like Zoroaster – traditionally assumed to have been a historical figure, although obscured by accretions from legend and myth. In Zoroastrian tradition, which builds on allusions found in the Avesta, Vishtaspa is a righteous king who helped propagate and defend the faith. In the non-Zoroastrian Sistan cycle texts, Vishtaspa is a loathsome ruler of the Kayanian dynasty who intentionally sends his eldest son to a certain death. In Greco-Roman literature, Zoroaster's patron was the pseudo-anonymous author of a set of prophecies written under his name. In scripture Vishtaspa is referred to in the Gathas, the oldest texts of Zoroastrianism which were considered to have been composed by Zoroaster himself. In these hymns, the poet speaks of Vishtaspa as his ally (Yasna 46. 14), follower of the path of Vohu Manah (Y. 51. 16), and committed to spreading the prophet's message (Y. 51. 16, 46. 15, 53. 2). In Yasna 28. 1–28. 7, Zoroaster appeals to Mazda for several boons, including the power to vanquish their foes for Vishtaspa and himself. Considered collectively, the Gathas celebrate Vishtaspa as the "patron of Zoroaster and the establisher of the first Zoroastrian community. " The Gathic allusions recur in the Yashts of the Younger Avesta. The appeal to Mazda for a boon reappears in Yasht 5. 98, where the boon is asked for the Haugvan and Naotara families, and in which Vishtaspa is said to be a member of the latter. Later in the same hymn, Zoroaster is described as appealing to Mazda to "bring Vishtaspa, son of Aurvataspa, to think according to Daena (Religion), to speak according to the Religion, to act according to the Religion." (Yt. 5. 104–105). In Yasht 9. 25–26, the last part of which is an adaptation of the Gathic Yasna 49. 7, the prophet makes the same appeal with regard to Hutaosa, wife of Vishtaspa. In Yasht 9. 130, Vishtaspa himself appeals for the ability to drive off the attacks of the daeva-worshipping Arejat.aspa and other members of drujvant Hyaona family. Similarly in Yasht 5. 109, Vishtaspa pleads for strength that he may "crush Tathryavant of the bad religion, the daeva-worshipper Peshana,
