ZOROASTER
Zoroaster
Zoroaster, also known as Zarathustra, was the founder of Zoroastrianism. Though he was a native speaker of Old Avestan and lived in the eastern part of the Iranian Plateau, his birthplace is uncertain. He is credited with the authorship of the Yasna Haptanghaiti as well as the Gathas, hymns which are at the liturgical core of Zoroastrianism. Most of his life is known through the Zoroastrian texts. Avestan, the language spoken by Zoroaster and used for composing the Yasna Haptanghaiti and the Gathas, on archaeological and linguistic grounds, is dated to have been spoken probably in the first half of the 2nd millennium BCE.The above text is a snippet from Wikipedia: Zoroaster
