Ἀπολλοδώρου. Ἀπολλόδωρος ἐν τῇ Φυσικῇ τέχνῃ κίνησιν εἶναι μεταβολὴν κατὰ τόπον ἢ σχῆμα ἢ ὅλῳ ἢ [τοῖς] μέρεσι· σχέσιν δὲ συνοχὴν κατὰ τόπον ἢ σχῆμα καὶ τὸ ἴσχεσθαι τοιοῦτο· γένη δὲ κινήσεως εἶναι πρῶτα δύο, τήν τε κατ’ εὐθεῖαν καὶ τὴν ἐγκύκλιον. Τούτων δὲ εἴδη γίνεσθαι πλείονα.
5 ⟨Ἀρείου Διδύμου⟩ · 2
Περὶ τὸ αὐτὸ δὲ κινήσεις γίνεσθαι πολλὰς καὶ ἐν τῷ αὐτῷ τόπῳ, οἷον περιπατεῖν καὶ τρέχειν μὴ ἐκβαίνοντα τὸν αὐτὸν τόπον, καὶ ἅμα κινεῖσθαι τήν τε ἐπ’ εὐθεῖαν καὶ τὴν εἰς τὰ πλάγια καὶ τὴν ἔμπροσθεν καὶ τὴν ὄπισθεν καὶ τὴν εἰς δεξιὰν καὶ ἀριστερὰν καὶ ἐγκύκλιον, καὶ ταχέως ἅμα καὶ βραδέως, καθάπερ ἐπὶ τῶν πλεόντων καὶ τῶν ὁμοίως τούτοις διακειμένων συντυγχάνειν.
Stobaeus, Volume I: Book I Chapter 19
p. 4455 ⟨Arius Didymus⟩: Apollodorus
Of Apollodorus. Apollodorus, in his Treatise on Physics, says that motion is a change in place or shape, in a whole or in [the] parts. Disposition is a holding together in place or shape, and being held in such a way.547 There are two primary kinds of motion, straight and circular; these have a number of species.548
5 Apollodorus: Simultaneous motions
Many motions can occur in the same thing and in the same place: for example, someone can walk and run without leaving that same place, and can move at once straight ahead, sideways, forward, backward, right, left, and in a circle, and both quickly and slowly at once, as happens with people sailing and others in similar circumstances.549
