Iliad 13, 459-461
βῆναι ἐπʼ Αἰνείαν· τὸν δʼ ὕστατον εὗρεν ὁμίλου
ἑσταότʼ· αἰεὶ γὰρ Πριάμῳ ἐπεμήνιε δίῳ
οὕνεκʼ ἄρʼ ἐσθλὸν ἐόντα μετʼ ἀνδράσιν οὔ τι τίεσκεν.
So, what's going on between Aeneas and Priamus? Ameis mentions rivalry. Is something more to be said about this, some other source than Homer for instance?
