“According to the best demonstration of the astrologers as we find it summarized in the book of the Constellations of the Stars, these movements are three: one according to which the star moves along its epicycle; a second according to which the epicycle moves together with the whole heaven in concert with that of the Sun; a third according to which that whole heaven moves, following the movement of the starry sphere, from west to east, one degree every one hundred years.” [via]
“These Thrones, who are assigned to govern this heaven, are not great in number, though the philosophers and the astrologers have estimated it diversely according to how diversely they have estimated its rotations, although all are agreed on this point: that there are as many of them as there are movements made by the heaven.” [via]
“That brings me to what is magic. The ordinary man is inclined to laugh at the word. He says that it is a phantom of the morbid and ignorant minds of the ancient and the Middle Ages.
Yet he is superstitious enough to believe in signs and omens, in astrologers and palmists, who claim to read destiny in stars and hands.” [via]
