Zoroaster probably lived in northwestern Persia possibly in the 7th century B.C. and possibly as early as 1200 B.C. The beliefs of Zoroaster, the religious prophet and founder of Zoroastrianism, were written down in a book called the "Zend Avesta."
The name Zoroaster is the Persian version of the name of this religious prophet. The Greek name of Zoroaster is Zarathushtra or Zarathustra. Zoroastrianism was the main religion of the Persian Empire around 600 B.C.
Zoroastrianism is still practiced, especially in India and Iran.
