“It is very pleasant, and you shall have all the gold and jewels you wish. […] If before you reach the upper world you look back to see her, you must lose her. […] Moreover I have brought you the sandals of Mercury, to help you on your way, and the helmet of Pluto, to make you invisible. […] I must leave you to-day, and you must care for our child alone. […] But you shall not, stranger, for I will save you from this danger also.”
