Θησεύς τινʹ ἡμάρτηκεν ἐς σʹ ἁμαρτίαν; (Euripides, Hippolytus 319)
This is one of the practice problems in my book (which doesn't provide answers). All I can gather is that someone is asking what kind of offense or error was committed by Theseus.
I tried finding it, but i can't distinguish text wrap from actual line breaks on some of the sites I went to.
