το της ανάγκης εστί αδήριτον σθένος – μοχθείν ανάγκη τους θέλοντας ευτυχείν / The first saying is found in the play of Prometheus Desmotis by the tragic poet Aeschylus (525-456 BC), where it is stated that the need creates irresistible vigor. A few years later, the tragic poet Euripides (480-406 BC) points out, in his play Telephos, that the people who seek happiness are those who toil and struggle out of necessity. The depiction is the ancient theatre of Aigeira with view to the Corinthian gulf (280-250 BC).
