Dio Chrysostom, Discourses
12.51 (on Phidias' statue of Zeus; tr. J.W. Cohoon):
Of men, whoever is sore distressed in soul, having in the course of his life drained the cup of many misfortunes and griefs, nor ever winning sweet sleep — even this man, methinks, if he stood before this image, would forget all the terrors and hardships that fall to our human lot.
ἀνθρώπων δέ, ὃς ἂν ᾖ παντελῶς ἐπίπονος τὴν ψυχήν, πολλὰς ἀναντλήσας συμφορὰς καὶ λύπας ἐν τῷ βίῳ μηδὲ ὕπνον ἡδὺν ἐπιβαλλόμενος, καὶ ὃς δοκεῖ μοι κατ' ἐναντίον στὰς τῆσδε τῆς εἰκόνος ἐκλαθέσθαι ἂν πάντων ὅσα ἐν ἀνθρωπίνῳ βίῳ δεινὰ καὶ χαλεπὰ γίγνεται παθεῖν.
