And the order of the houses is this, that the first that they enumerate is that where the Moon is; the second is that where Mercury is; the third is that where Venus is; the fourth is that where the Sun is; the fifth is that where Mars is; the sixth is that where Jupiter is; the seventh is that where Saturn is; the eighth is that of the Stars; the ninth is that which is not visible except by that movement which is mentioned above, which they designate the great Crystalline sphere, diaphanous, or rather all transparent. Truly, beyond all these, the Catholics place the Empyrean Heaven, which is as much as to say, the Heaven of Flame, or rather the Luminous Heaven; and they assign it to be immoveable, in order to have in itself, according to each part, that which its material desires. And this is why that first moved--the Primum Mobile--has such extremely rapid motion. For, because of the most fervent appetite which each part of it has to be united with each part of that most Divine Heaven of Peace, in which it revolves with so much desire, its velocity is almost incomprehensible. And this quiet and peaceful Heaven is the place of that Supreme Deity who from above beholds the whole. This is the place of the blessed Spirits, according as Holy Church teaches, which cannot speak falsely; and even Aristotle seems to feel this, to him who understands him well, in the first book of Heaven and the World. This is the highest bound of the World, within which the whole World is included, and beyond which there is nothing. And it is in no place, but was formed alone in the First Mind, which the Greeks term Protonoe. This is that magnificence of which the Psalmist spoke when he sang to God: "Thy glory is raised above the Heavens."
