Wolf-teeth on the bridle for speed
On the speed of horses. The speed of horses is blunted and it increases. [The text is damaged here.] a wolf as a counter-charm stands to each, and the two feet go numb; more quickly it comes to earth under a wolf. Wolf-feet are a possession horsemen seek after, and an astragalus of the same beast, hung on, also checks a runner. Rare, then, is the wounding and thinning that can happen.
We found another way the wolf can help toward swiftness, without harm to the horse. The canine teeth, taken out of a living wolf, are woven into the neck-pieces and contribute to both: they are an unsuspected help, and an ornament of contest-trappings. It is a fine thing if a man attach it to the whole four-horse team; if not, even the lead horse alone, having this wrapping, is enough to make the co-runners faster.
Greek
1.10 Περὶ ἵππων τάχουσ Ἵππων τάχος ἀμβλύνεται καὶ αὔξει· † λύκος ἀντιπαθὲς ἑκάστη ἵσταται καὶ ναρκᾷ τὼ πόδε θᾶττον δὲ αὐτοῦ χθονὶ ὑπὸ λύκου γίγνεται †. Περισπούδαστον ἱππόταις κτῆμα λύκου πόδες, καὶ ἀπαρτηθεὶς δὲ ἀστράγαλος τοῦ αὐτοῦ θηρίου ἐπιστομίζει τρέχοντα. Σπάνιον μὲν οὖν, τὸ τρωθῆναι καὶ ἀραιῶσαι συμβῆναι δυνάμενον. Εὕρομεν δ' ἑτέρως τὸν λύκον συνεργῆσαι δυνάμενον εἰς ὠκύτητα, δίχα τῆς τοῦ ἵππου βλάβης. Οἱ γάρ τοι κυνόδοντες ζῶντος ἐξαιρεθέντες τοῖς περιδεραίοις συμπλέκονται καὶ εἰς ἀμφότερα συμβάλλονται· ἀνύποπτός τε εἶναι βοήθεια καὶ φαλάρων κόσμος ἐναγωνίων. Καλὸν μὲν οὖν, εἰ τῷ τετραόρῳ τις παντὶ προσαρτήσειεν· εἰ δ' οὖν, κἂν ὁ ἡγεμὼν μόνος ἵππος τὸ περίθεμα ἔχων τοῦτο θάττονας ποιῆσαι τοὺς συντρέχοντας ἀρκεῖ.
