Hesiod, Works and Days
729-732 (tr. Thomas Cooke):
When you would have your urine pass away,
Stand not upright before the eye of day;
And scatter not your water as you go,
Nor let it, when you're naked, from you flow:
In either case 'tis an unseemly sight:
The gods observe alike by day and night:
The man that we devout and wise may call
Sits in that act, or streams against a wall.
μήτ' ἐν ὁδῷ μήτ' ἐκτὸς ὁδοῦ προβάδην οὐρήσῃς
μηδ' ἀπογυμνωθείς· μακάρων τοι νύκτες ἔασιν· 730
ἑζόμενος δ' ὅ γε θεῖος ἀνήρ, πεπνυμένα εἰδώς,
ἢ ὅ γε πρὸς τοῖχον πελάσας ἐυερκέος αὐλῆς.
