Agni, the god of fire, was an ancient Aryan deity who was often exalted as the head of the Vedic pantheon. [1]
Around 16,000 BC India was almost conquered to the idea of the Trinity but then in five thousand years it degenerated into the triune symbol of the fire god, Agni. In the early second millennium BC the Aryan gods organized themselves under the leadership of Dyaus pitar, of the sky, Indra, of the air, and Agni, of the fire. Agni, the three-headed god of fire, was long one of the few remnants of the ideas about the Trinity that Adam and Eve and later Melchizedek began to spread in ancient times. [2]
