The obscure religion that shaped the West
It is generally believed by scholars that the ancient Iranian prophet Zarathustra (known in Persian as Zartosht and Greek as Zoroaster) lived sometime between 1500 and 1000 BC. Prior to Zarathustra, the ancient Persians worshipped the deities of the old Irano-Aryan religion, a counterpart to the Indo-Aryan religion that would come to be known as Hinduism. Zarathustra, however, condemned this practice, and preached that God alone - Ahura Mazda, the Lord of Wisdom – should be worshipped. In doing so, he not only contributed to the great divide between the Iranian and Indian Aryans, but arguably introduced to mankind its first monotheistic faith.
