I'm dragging through my old files, something I wrote down as I researched CH XIII: this is my place-holder, apologies. I dimly recall finding some Hermetic material on this.
CH 13.17: μέλλω γὰρ ὑμνεῖν τὸν κτίσαντα τὰ πάντα͵ τὸν πήξαντα τὴν γῆν καὶ οὐρανὸν κρεμάσαντα ...
For I am going to praise him who created all things, the One who established the earth and suspended heaven, ...
For I will sing the praise of Him who founded all; who fixed the Earth, and hung up Heaven ...
Proclus quotes Julian the Theurgist at several points, which
Lewy (1956), pp.123–25 assembles and translates as follows: ‘The Demiurge bent heaven into a curved shape, and attached to it the great multitude of the fixed stars, forcing fire to fire, so that they may not move through wearisome strain, but by a fixture that is not subject to vagaries. He sent underneath six planets, and in their midst the seventh: the fire of the Sun;
and he suspended their disorder on the well-ranged girdles of the spheres.’
