Plato, Laws 822a

ὃ θαυμαστὸν μὲν λέγεις, προσῆκον δʼ αὖ μαθεῖν τοῖς νέοις, οὐ γιγνώσκειν δὲ ἡμᾶς; πειρῶ περὶ αὐτοῦ τό γε τοσοῦτον φράζειν ὡς σαφέστατα. πειρατέον. οὐ γάρ ἐστι τοῦτο, ὦ ἄριστοι, τὸ δόγμα ὀρθὸν περὶ σελήνης τε καὶ ἡλίου καὶ τῶν ἄλλων ἄστρων, ὡς ἄρα πλανᾶταί ποτε, πᾶν δὲ τοὐναντίον ἔχει τούτου—τὴν αὐτὴν γὰρ αὐτῶν ὁδὸν ἕκαστον καὶ οὐ πολλὰς ἀλλὰ μίαν ἀεὶ κύκλῳ διεξέρχεται, φαίνεται δὲ πολλὰς φερόμενον—τὸ δὲ τάχιστον αὐτῶν ὂν βραδύτατον οὐκ ὀρθῶς αὖ δοξάζεται, τὸ δʼ ἐναντίον

Do try to tell us thus much, at least, about it, with all possible clearness, I must try. The opinion, my friends, that the Sun and Moon and the rest of the stars wander is not correct; the truth is precisely the opposite: each of them always travels in a circle one and the same path,—not many paths, although it appears to move along many paths; and the quickest of the stars is wrongly opined to be the slowest, and vice versa.
