testifies in the first book of the Æneid, where Venus says to Love:
"Oh! son, my virtue, son of the great Father, who takest no heed of
the darts of Typhoeus." And Ovid so testifies in the fifth book of
his Metamorphoses, when he says that Venus said to Love: "Son, my
arms, my power." And there are Thrones which are ordered to the
government of this Heaven in number not great, concerning which the
Philosophers and the Astrologers have thought differently, according
as they held different opinions concerning its revolutions. But all
may be agreed, as many are, in this, as to how many movements it
makes. Of this, as abbreviated in the book of the Aggregation of the
Stars, you may find in the better demonstration of the Astrologers
that there are three: one, according as the star moves towards its
Epicycle; the other, according as the Epicycle moves with its whole
Heaven equally with that of the Sun; the third, according as the whole
of that Heaven moves, following the movement of the starry sphere from
West to East in one hundred years one degree. So that to these Three
Movements there are Three Movers. Again, if the whole of this Heaven
moves and turns with the Epicycle from East to West once in each
natural day, that movement, whether it be caused by some Intelligence
or whether it be through the rapid movement of the Primum Mobile, God
knows, for to me it seems presumptuous to judge. These Movers produce,
caring for that alone, the revolution proper to that sphere which each
one moves. The most noble form of the Heaven, which has in itself the
principle of this passive Nature, revolves, touched by the Moving
Power, which cares for this; and I say touched, not by a bodily touch,
but by a Power which directs itself to that operation. And these
Movers are those to whom I begin to speak and to whom I put my
inquiry.
