Passage 1.21.5
ἐνταῦθα ἄλλα τε καὶ Σαυροματικὸς ἀνάκειται θώραξ· ἐς τοῦτόν τις ἰδὼν οὐδὲν ἧσσον Ἑλλήνων τοὺς βαρβάρους φήσει σοφοὺς ἐς τὰς τέχνας εἶναι. Σαυρομάταις γὰρ οὔτε αὐτοῖς σίδηρός ἐστιν ὀρυσσόμενος οὔτε σφίσιν ἐσάγουσιν· ἄμικτοι γὰρ μάλιστα τῶν ταύτῃ βαρβάρων εἰσί. πρὸς οὖν τὴν ἀπορίαν ταύτην ἐξεύρηταί σφισιν· ἐπὶ μὲν τοῖς δόρασιν αἰχμὰς ὀστεΐνας ἀντὶ σιδήρου φοροῦσι, τόξα τε κράνινα καὶ ὀιστοὺς καὶ ὀστεΐνας ἀκίδας ἐπὶ τοῖς ὀιστοῖς· καὶ σειραῖς περιβαλόντες τῶν πολεμίων ὁπόσους καὶ τύχοιεν, τοὺς ἵππους ἀποστρέψαντες ἀνατρέπουσι τοὺς ἐνσχεθέντας ταῖς σειραῖς.
Here among other objects is placed a Sarmatian breastplate; whoever sees this will declare that the barbarians are no less ingenious in craftsmanship than the Greeks themselves. The Sarmatians neither have iron ore mined in their own land nor do they import it from abroad; for they are especially isolated among the barbarians in these parts. Therefore they have devised the following solution to this shortage: instead of iron, they fit their spearheads with bone points, and use bows made of horn, arrows, and bone-tipped darts. They also throw ropes around their enemies and, when they catch them, they wheel their horses about and overturn those thus entangled.
