ÒFor the Spirit being one,
and holding the place of light, was between the
water and the heaven, in order that the darkness
might not in any way communicate with the
heaven, which was nearer God, before God
said, ÔLet there be light.Õ The heaven, therefore, being like a dome-shaped covering,
comprehended matter, which was like a
clod.Ó
Theophilus
to Autolycus 2:13
