For this reason the altar, as representative of the universe, is built in five layers, representing earth, air and heaven, and the intermediate regions; and in the centre of the altar-site, below the first layer, on a circular gold plate (the sun), a small golden man (purusha) is laid down with his face looking upwards.
He too is chiefly a creative or demiurgic being, answering to Purusha in the Rig Veda.
Ptah is the Egyptian Hephaestus; he is represented as a dwarf; men are said to have come out of his eye, gods out of his mouth - a story like that of Purusha in the Rig Veda.
The " Purusha Sukta," the 90th hymn of the tenth book of the Rig Veda, gives us the Indian version of the theory that all things were made out of the mangled limbs of Purusha, a magnified non-natural man, who was sacrificed by the gods.
A being named Purusha was alone in the world.
