What’s this? –
you, the son of Tydeus, that skilled breaker of horses?
Why cringing here? Gazing out on the passageways of battle!
That was never Tydeus’ way, shy behind the lines –
he’d grapple enemies, bolting ahead of comrades.
…Now there was a man, that Tydeus, that Aetolian.
But he bore a son who’s not the half of him in battle.
– Homer
The Iliad, Book 4, lines 430-434, 465-466. Agamemnon rebukes Diomedes for his timidity in the face of battle, when he finds him standing by in the combat car. In an effort to spur Diomedes on by appealing to his pride, Agamemnon mentions the heroic and glorious feats of Diomedes’s father Tydeus, adding that Diomedes is not half the man he was in battle.
