94:1.3
The polytheism of these Aryans represented a degeneration of their earlier monotheism occasioned by their separation into tribal units, each tribe having its venerated god. This devolution of the original monotheism and trinitarianism of Andite Mesopotamia was in process of resynthesis in the early centuries of the second millennium before Christ. The many gods were organized into a pantheon under the triune leadership of Dyaus pitar, the lord of heaven; Indra, the tempestuous lord of the atmosphere; and Agni, the three-headed fire god, lord of the earth and the vestigial symbol of an earlier Trinity concept.
