Passage 7.10.6
Περσεῖ τῷ Φιλίππου πρὸς Ῥωμαίους ἄγοντι εἰρήνην κατὰ συνθήκας, ἃς ὁ πατήρ οἱ Φίλιππος ἐποιήσατο, ἐπῆλθεν ὑπερβῆναι τοὺς ὅρκους καὶ ἐπί τε Σαπαίους καὶ Σαπαίων τὸν βασιλέα Ἀβρούπολιν στράτευμα ἀγαγὼν ἐποίησεν ἀναστάτους Ῥωμαίων συμμάχους ὄντας· Σαπαίων δὲ τούτων καὶ Ἀρχίλοχος ἐν ἰάμβῳ μνήμην ἔσχε.
Perseus, the son of Philip, having peace with the Romans according to the treaty that his father Philip had made, was led to violate his oaths; he marched an army against the Sapaeans and their king Abrupolis, and laid waste their territory, though they were allies of the Romans. Of these Sapaeans even Archilochus made mention in one of his iambic poems.
