Aratus says that there are in the sky revolving, that is, gyrating stars, because from east to west, and west to east, they journey perpetually, (and) in an orbicular figure. And he says that there revolves towards “The Bears” themselves, like some stream of a river, an enormous and prodigious monster, (the) Serpent; and that this is what the devil says in the book of Job to the Deity, when (Satan) uses these words: “I have traversed earth under heaven, and have gone around (it),” that is, that I have been turned around, and thereby have been able to survey the worlds. For they suppose that towards the North Pole is situated the Dragon, the Serpent, from the highest pole looking upon all (the objects), and gazing on all the works of creation, in order that nothing of the things that are being made may escape his notice. For though all the stars in the firmament set, the pole of this (luminary) alone never sets, but, careering high above the horizon, surveys and beholds all things, and none of the works of creation, he says, can escape his notice.
