τὸν μὲν ποιητὴν οἶσθα οἷός τε ἦν καὶ ἡλίκα ἐτραγῴδει παρʼ ὅλον τὸν βίον, ὑπὲρ τὸν Σοφοκλέα καὶ τὸν Αἰσχύλον.
Now, I know what it's supposed to say, but I'm having trouble with the exact force of οἷός τε ἦν. Normally this is idiomatic for "be able" or "be capable" but that doesn't seem really to fit here, since it would normally be followed with an infinitive. This online English translation is not at all helpful in seeing the Greek construction, although I instinctively read it similarly:
I liked the French translation:As to our author, I say nothing: you know the man, you know the sublime utterances that marked his earthly course, outvoicing Sophocles and Aeschylus.
Any suggestions appreciated... .Tu connais le poète, tu sais qu'il a joué la tragédie toute sa vie, à détrôner Sophocle et Eschyle.
