Note 829 — Chapter VII · THE PYTHAGOREANS
Reading edition
In his letter to Pope Paul III., Copernicus quotes Plut. Plac. iii. 13, 2-3 (R. P. 83 a), and adds “Inde igitur occasionem nactus, coepi et ego de terrae mobilitate cogitare.” The whole passage is paraphrased by Dreyer, Planetary Systems, p. 311. Cf. also the passage from the original MS., which was first printed in the edition of 1873, translated by Dreyer, ib. pp. 314 sqq.
