Greek proverb: τραγῳδία καὶ κωμῳδία

Here's a saying from Apostolius, C6.92, with a Latin version from Clavis Homerica. The image is from kurto at Flickr. Here are some more Apostolius proverbs.

Ἐκ τῶν αὐτῶν τραγῳδία γίνεται καὶ κωμῳδία γραμμάτων.
Ex iisdem tragedia fit et comedia litteris.
Tragedy and comedy are composed of the same letters.
