The Gathas of Zarathustra
The Hymns of Zoroaster
The Gathas of Zarathustra are seventeen hymns composed by the prophet Zarathustra (Zoroaster), possibly in the 2nd millennium BC — making them among the oldest religious poetry in any Indo-European language. They describe a cosmic struggle between Ahura Mazda (the Wise Lord, truth) and Angra Mainyu (the Destructive Spirit, lie) — a dualistic framework that directly influenced Jewish apocalypticism
