AETHER

Aether was the Protogenos (first-born elemental god) of the bright, glowing upper air of heaven - the substance of light. Above him lay the solid dome of the sky-god, Ouranos, and below, the transparent mists of earth-bound air. In the evening his mother Nyx drew her veil of darkness between the aither and the aer to bring night to man. In the morn his sister-wife Hemera dispersed these mists, revealing the shining blue aither of day. Night and day were regarded as quite independent of the sun in the ancient cosmogonies. Aither was one of the three "airs".
