πολλὰ τὰ δεινὰ κοὐδὲν ἀν- θρώπου δεινότερον πέλει. τοῦτο καὶ πολιοῦ πέραν πόντου χειμερίῳ νότῳ χωρεῖ, περιβρυχίοισιν περῶν ὑπ’ οἴδμασιν
Sophocles, Antigone
Many things are formidable, and none more formidable than man! He crosses the gray sea beneath the winter wind, passing beneath the surges that surround him; and he wears away the highest of the gods, Earth, immortal and unwearying, as his ploughs go back and forth from year to year, turning the soil with the aid of the breed of horses.
