We are women: in some things, we hesitate.
But in others, no one can surpass our courage.

[γυναῖκές ἐσμεν: τὰ μὲν ὄκνῳ νικώμεθα,
τὰ δ᾽ οὐκ ἂν ἡμῶν θράσος ὑπερβάλοιτό τις.]

Euripides (485?-406? BC) Greek tragic dramatist

Auge [Αὐγῃ], frag. 276 (c. 408 BC) [tr. @sentantiq (2014)]

Nauck (TGF) frag. 276, Barnes frag. 18, Musgrave frag. 4. (Source (Greek)). Alternate translations:

Frail women as we are, too oft our fears
Subdue us, but at other times our courage
By none can be exceeded.
[tr. Wodhall (1809)]

We are women, sometimes defeated by fear,
sometimes unsurpassed in courage.
