These sayings come from the Gnomologium Vaticanum
168 “Diogenes, when he saw a small city with big gates, said “Lock the gates so the city can’t escape!”
Διογένης θεασάμενος μικρὰν πόλιν μεγάλας πύλας ἔχουσαν ἔφη· „κλείσατε τὰς πύλας, μὴ ἡ πόλις ἐξέλθῃ”.
189 “When [Diogenes] was asked what is evil in life, he said “A pretty woman.”
῾Ο αὐτὸς ἐρωτηθεὶς τί κακὸν ἐν βίῳ ἔφη· „γυνὴ καλὴ τῷ εἴδει”.
201 “[Diogenes] to say that he had everything that happened in the tragedies: for he was a beggar, a wanderer, and he had an ephemeral life.”
῾Ο αὐτὸς ἔφη πάντα ἔχειν τὰ ἐν ταῖς τραγῳδίαις· εἶναί τε γὰρ πτωχός, πλανήτης, βίον ἔχων ἐφήμερον·
