Yazd Mehregan Festival in Yazd
Mehregan, the Zoroastrian autumn equinox festival honoring Mithra, survives most prominently in Yazd, where fire-temple hymns, an autumn sofreh table set with seasonal fruit and incense, and, in some villages, a Mehr-dedicated sheep sacrifice mark a celebration once ranked second in importance only to Nowruz.
Mehregan falls at the start of the Persian month of Mehr, on or near the autumn equinox, honoring the ancient Zoroastrian deity Mithra, associated with friendship, covenant, and light, in a celebration that under the Achaemenid and Sasanian empires ranked second in importance only to Nowruz.
