Avestan

Liturgical language of Zoroastrianism originating in the Old Iranian period

Avestan ( ə-VESS-tən) is the liturgical language of Zoroastrianism. It belongs to the Iranian branch of the Indo-European language family and was originally spoken during the Avestan period (c. 1500 – c. 400 BCE) by the Iranians living in eastern Greater Iran as evidenced from names in Avestan geography. After Avestan became extinct, its religious texts were transmitted orally, then collected and put into writing during the Sasanian period (c. 400 – c. 500 CE).
