Diod. Sic. lib. iii.
Ουκ εστιν ουδεν πιςτον, ουτ ευδοξια,
Ουτ' αν καλως πρασσοντα μη πραξειν κακως.
Φυρουσι δ'αυθ'οι θεοι παλιν τε και προσω,
Ταραγμον εντιθεντες, ως αγνωσια
Σεβωμεν αυτους. Hecuba.
There is nothing secure in the world; no glory, no prosperity. The gods toss all life into confusion; mix every thing with its reverse; that all of us, from our ignorance and uncertainty, may pay them the more worship and reverence.
