What did Hermes warn Orpheus about leaving Hades? What happened?

Answer 1

Here i will give you the whole story.. but i like this guys answer, but i will still tell you anyway.

Orpheus is best known for his ill-fated marriage to the lovely nymph Eurydice. Soon after the wedding the bride was stung by a viper and died. Overwhelmed with grief, Orpheus determined to go to the underworld and try to bring her back, something no mortal had ever done. Hades, the ruler of the underworld, was so moved by his playing that he gave Eurydice back to Orpheus on the one condition that he not look back until they reached the upperworld. Orpheus could not control his eagerness, however, and as he gained the light of day he looked back a moment too soon, and Eurydice vanished. In his despair, Orpheus forsook human company and wandered in the wilds, playing for the rocks and trees and rivers. Finally a fierce band of Thracian women, who were followers of the god Dionysus, came upon the gentle musician and killed him. When they threw his severed head in the river Hebrus, it continued to call for Eurydice, and was finally carried to the shore of Lesbos, where the Muses buried it. After Orpheus's death his lyre became the constellation Lyra.

and hermes was not there...

Answer 2

There must be a reason that some of the conditioners say not to exceed a certain time frame. Those probably shouldn't be left in your hair. Regular old conditioners won't do any damage, even if left on for a few days. The worst you'd have to worry about is debris getting caught in it, so just take a good look before you leave the house and you'll be fine.

Answer 3

I don't think Hermes was there, but...

Orpheus was told his dead wife Eurydice could follow him back to the land of the living, but only if he did not look behind himself to see if she was there.

He got almost all the way out, but looked back; thus she could not return to the land of the living.
