Tartarus

TARTAROS (Tartarus) was the primordial god (protogenos) of the stormy pit of Tartaros that lies beneath the foundations of the earth. He was the body of the pit itself rather than an athropomorphic deity.

Tartaros was envisaged as the opposite of the sky, an inverted-dome lying beneath the flat earth. Together the Ouranion-dome and Tartarean-pit enclosed the entire cosmos in an egg-shaped or spherical shell.
