ἀκαμαντομάχης
From LSJ
Εὐφήμει, ὦ ἄνθρωπε· ἁσμενέστατα μέντοι αὐτὸ ἀπέφυγον, ὥσπερ λυττῶντά τινα καὶ ἄγριον δεσπότην ἀποδράς → Hush, man, most gladly have I escaped this thing you talk of, as if I had run away from a raging and savage beast of a master
Greek (Liddell-Scott)
ἀκᾰμαντομάχης: -ου, ὁ, ἀκάματος ἐν μάχῃ, Πινδ. Π. 4. 304.
