below Mars, on the side not shining, and Mars to remain concealed so
long that he re-appeared on the other bright side of the Moon, which
was towards the West.

CHAPTER IV.

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."

So, then, gathering together this which is discussed, it seems that
there may be ten Heavens, of which the Heaven of Venus may be the
third; whereof mention is made in that part which I intend to
demonstrate. And it is to be known that each Heaven below the
Crystalline has two firm poles as to itself; and the ninth has them
firm and fixed, and not mutable in any respect. And each one, the
ninth even as the others, has a circle, which one may term the equator
of its own Heaven; which equally, in each part of its revolution, i
