Plato on Mercury (planet)

“As the whorls differ from one another in respect of “ breadth of rim”, the first and outermost whorl is that which has its circular rim the broadest, and the sixth whorl comes next to it in regard to breadth of rim; and, proceeding in order of breadth, the fourth whorl comes third, and the eighth fourth, and the seventh fifth, and the fifth sixth, and the third seventh, and the second eighth.' Thus we have now a new classification of the heavenly bodies, in the following sequence: 1. The Fixed Stars. 2. Venus. 3. Mars. 4. The Moon. 5. The Sun. 6. Mercury. 7. Jupiter. 8. Saturn.”

“The Spirits survey the heavens and the earth and all the harmonious motions of the universe. They see the heavenly bodies set in revolving whorls, which, whorl within whorl, combine to form the Spinning-whorl on the Spindle of Necessity; and the Goddess holds the spindle on her knee, and spins the thread which the Fates wind, unwind and cut. The heavenly bodies, or the spheres or whorls in which they lie, are arranged one within another in the following order: 1. The Fixed Stars. 2. Saturn. 3. Jupiter. 4. Mars. 5. Mercury. 6. Venus. 7. The Sun. 8. The Moon. This order is as good as any other that can be framed under a geocentric hypothesis.”
