Tishtrya

Deities

Tishtrya is the yazata of the star Sirius and of the rains, whose hymn is Yasht 8 of the Avesta: as a shining white horse he fights the drought demon Apaosha, is weakened when the sacrifice is withheld and strengthened by the offering of haoma, and by his victory the waters flow and the harvest is assured.

A note on this entry

Living tradition: Tishtrya is a yazata of the Avesta, worshipped today at Tiragan and invoked for rain, and the tradition's own account is primary. The 'Mercury' correspondence rests on a naming coincidence only - Tir is the later Persian name of Mercury and of the fourth month, while Tishtrya is the star Sirius - and it is not an ancient rulership; the planetary (Mercury/Moon), zodiacal (Cancer/Aquarius), tarot and the litha sabbat values are modern Western overlays. The Egyptian identification of Sirius with Isis (Sothis) is a different tradition's reading and is not a claim of sameness.

Modern Practice

Invoked for rain, for the relief of drought and for the keeping of the agricultural year; modern correspondence work uses him for the timing of seasons, for patience under dry conditions, and for the defeat of what starves a land.

Mythology Summary

Tishtrya is the yazata of the star Sirius and of the rains, whose hymn is Yasht 8 of the Avesta: as a shining white horse he fights the drought demon Apaosha, is weakened when the sacrifice is withheld and strengthened by the offering of haoma, and by his victory the waters flow and the harvest is assured. His festival, Tiragan, is kept in early summer and is bound up with rain and with the arrow-legends of Arash, and the star's cycle is one of the tradition's markers of the year. The Persian name Tir is also the name of the planet Mercury, but Tishtrya's own identity in the Avesta is the star, not a planet.
