Ahura Mazda vs Atar

The Wise Lord, uncreated creator of the good world in Zoroastrianism, addressed by Zarathushtra in the Gathas and credited by the Achaemenid kings with their rule; opposed by the Hostile Spirit, Angra Mainyu.

Uncreated in orthodox Zoroastrianism. In the Sasanian-era Zurvanite current, known mainly from Christian and Armenian polemic, Ohrmazd and Ahriman are twin sons of Zurvan, Infinite Time.

Zarathushtra's hymns address Ahura Mazda as the creator who established the earth below and held up the sky, who ordered the paths of sun and stars, and who is the father of the good powers: Truth (*Asha*), Good Mind (*Vohu Manah*), and Devotion (*Armaiti*), whom one hymn calls his daughter. The Gathas are hymns of questioning and devotion rather than narratives; they present a world in which every being must choose between truth and the lie, and in which the Wise Lord will judge by that choice.

Fire as a divine being, 'son of Ahura Mazda', the visible focus of Zoroastrian worship, who in the Zamyad Yasht faces down the three-mouthed dragon Azhi Dahaka in the struggle for the royal Glory.

Son of Ahura Mazda, in the standard Avestan formula.

The Avesta calls Atar, fire, 'the son of Ahura Mazda', and fire is the element through which Zoroastrians approach God: prayers are said facing a fire or another source of light, and consecrated fires are kept burning in fire temples. Fire is not itself worshipped as God, Zoroastrians emphasize, but honored as the purest of creations and the symbol of truth and divine light.
