The Iliad 23.658–663
Let him to whom Apollo shall grant strength to endure, and all the Achaeans have knowledge thereof, go his way to his hut leading the sturdy muIe; but he that is worsted shall bear as his prize the two-handled cup.
Ἀτρεΐδη τε καὶ ἄλλοι ἐϋκνήμιδες Ἀχαιοὶ
ἄνδρε δύω περὶ τῶνδε κελεύομεν, ὥ περ ἀρίστω,
πὺξ μάλʼ ἀνασχομένω πεπληγέμεν· ᾧ δέ κʼ Ἀπόλλων
δώῃ καμμονίην, γνώωσι δὲ πάντες Ἀχαιοί,
ἡμίονον ταλαεργὸν ἄγων κλισίην δὲ νεέσθω·
αὐτὰρ ὃ νικηθεὶς δέπας οἴσεται ἀμφικύπελλον.
