“Our conversation will be superfluous if
We praise nobility in human birth.
For long ago at the moment we were first created
And the earth produced mortals one could distinguish
She raised us all up with similar appearance.
We have no special trait. One race
Are the well-born and the low-born.
Time makes some haughty with custom.
But god makes some noble with intelligence
and understanding, not wealth….”

περισσόμυθος ὁ λόγος, εὐγένειαν εἰ
βρότειον εὐλογήσομεν.
τὸ γὰρ πάλαι καὶ πρῶτον ὅτ’ ἐγενόμεθα,
διὰ δ’ ἔκρινεν ἁ τεκοῦσα γᾶ βροτούς,
ὁμοίαν χθὼν ἅπασιν ἐξεπαίδευσεν ὄψιν.
ἴδιον οὐδὲν ἔσχομεν• μία δὲ γονὰ
τό τ’ εὐγενὲς καὶ τὸ δυσγενές•
νόμῳ δὲ γαῦρον αὐτὸ κραίνει χρόνος.
τὸ φρόνιμον εὐγένεια καὶ τὸ συνετὸν
ὁ θεὸς δίδωσιν, οὐχ ὁ πλοῦτος.

This is from Euripides’ lost play Alexandros.
