ATAR.
This is the god of fire. He was called the “most great Yazata,” and as such he commanded the undying worship of the Persian devotee.
The first duty of each Pārsī householder was to cherish the sacred fire upon his own hearth, feeding it only with delicate bits of fragrant sandal wood, while the fires in the temples were committed to the care of the priests. Atar is the Persian form of the Hindū Agni, the guardian of the home, and the symbol of social union.
The cypress tree was planted in front of their fire temples, and when it had reached a towering height, it was surrounded by a gilded palace like a sheath of flame,[[137]] while more simple altars arose from their mountain tops and blazed with the sacred symbol.
