A wolf’s right-fore ankle-bone stops horses
On making horses unmovable from the same place. Laboring at the exposition of the present writing, I read in Neptunianus's Physica that a wolf's ankle-bone of the right forefoot, thrown before a four-horse team, stops the chariot. If then it stops four, how much more when in battle-line we give one each to a few slingers? When they have thrown these into the enemy's horse, not only will the one ankle-bone harm one horse, but as many as happen to ride past through it.

2.4 Περὶ τοῦ τοὺς ἵππους ἐκ τοῦ αὐτοῦ τόπου ἀμετακινήτους ποιεῖν Φιλοπονῶν περὶ τὴν τοῦ παρόντος συγγράμματος ἔκθεσιν, ἀνέγνων ἐν τοῖς Νεπτουνιανοῦ «Φυσικοῖς» ὅτι λύκου ἀστράγαλος δεξιοῦ ποδὸς τοῦ ἐμπροσθίου ῥιφεὶς πρὸ τετραόρου ἵστησι τὸ ἅρμα. Εἴπερ οὖν τέσσαρας ἵστησι, πόσῳ μᾶλλον ὅτ' ἐν παρατάξει καθ' ἕνα δώσομεν ὀλίγοις σφενδονήταις; Τούτους ῥιψάντων αὐτῶν εἰς τὴν τῶν πολεμίων ἵππον, οὐ μόνον ὁ εἷς ἀστράγαλος ἵππον ἕνα κακοποιήσει, ἀλλ' ὅσους <ἂν> συμβῇ δι' αὐτοῦ παριππάζειν.
