Here is Homer's Iliad, lines 6-10.
ἐξ οὗ δὴ τὰ πρῶτα διαστήτην ἐρίσαντε
Ἀτρεΐδης τε ἄναξ ἀνδρῶν καὶ δῖος Ἀχιλλεύς.
τίς τ᾽ ἄρ σφωε θεῶν ἔριδι ξυνέηκε μάχεσθαι;
Λητοῦς καὶ Διὸς υἱός: ὃ γὰρ βασιλῆϊ χολωθεὶς
νοῦσον ἀνὰ στρατὸν ὄρσε κακήν, ὀλέκοντο δὲ λαοί...
Here's my unorthodox translation.
In this age when the best stood out,
Atreus' son, leader of men, quarreled with godlike Achilles.
Who among the gods had brought these two to blows?
Leto and Zeus' boy. Mad at the mortal king,
He plagued the army. Agamemnon's troops were perishing.
