Deity
Aether
The bright upper air born from Nyx and Erebus, paired with Hemera after the first darkness.

Overview
Aether is the bright upper air born from Nyx and Erebus in Hesiod’s Theogony. The name is not the later scientific ether; in the primordial genealogy it marks the high brightness that follows night and darkness. Placing Aether after Chaos, Nyx and Erebus shows how Hesiod arranges the move from dark conditions toward visible light through kinship.
