“How dark lies honour hid! And what turmoil
In all things human: sons of mighty men
Fallen to naught, and from ill seed again
Good fruit: yea, famine in the rich man's scroll
Writ deep, and in poor flesh a lordly soul.
As, lo, this man, not great in Argos, not
With pride of house uplifted, in a lot
Of unmarked life hath shown a prince's grace.”
Orestes in Electra by Euripides
