Here's a saying from
Apostolius, C4.45, with a Latin version from
Clavis Homerica. The image is of the god Hermes/Mercury at
Wikipedia. Here are some
more Apostolius proverbs. The words allude to the fable of
Mercury and the Fishermen.
Αὐτοὶ χελώνας ἐσθίετε.
Ipsi testudines edite.
Eat the turtles yourselves.
