Greek proverb: τὸ σιγᾶν

Here's a saying from Apostolius, C4.9, with a Latin version from Clavis Homerica. The image is from Black Country Museums at Flickr. Here are some more Apostolius proverbs.

Ἀσφαλέστερον γὰρ τοῦ λέγειν τὸ σιγᾶν.
Tutius est tacere quam loqui.
It is safer to keep quiet than to speak.
