Plutus. Aristophanes

The story of ‘Plutus’ concerns Chremylus, a poor but just man, who accompanied by his body-servant Cario, consults the Delphic Oracle concerning his son, whether he ought not to be instructed in injustice and knavery and the other arts whereby worldly men acquire riches. By way of answer the god only tells him that he is to follow whomsoever he first meets upon leaving the temple, who proves to be a blind and ragged old man.
