Question

Why did orpheus look back to see if eurydice is following him

Answer 1

Answer:

For lack of trust.

Explanation:

The myth of Orpheus, one of the very few and select mythological heroes that get to descend into Hades and come back to the world of the living, tells the story of how this hero went to the underworld to rescue his wife from death and bring her back to life, a favor that, through his beautiful music, is granted to him. However, there is only one condition, that he does not look back to corroborate if Eurydice is in fact walking behind him, back to the world of the living. He looks back, perhaps worried that she is not behind him, perhaps doubting her and her determination, perhaps doubting the fate that the gods have granted him; and in looking back, she loses her forever.

Answer 2

Orpheus is the son of one of the Muses and a Thracian Prince. His wife, Eurydice, was stung by a viper and died after their wedding. Orpheus went to the underworld to bring his dead wife back. He stroke his lyre there in the underworld which took the madness of all creatures, the reason why Hades permitted him to take his wife back but in one condition: as he and his wife ascend to heaven, he must never look back down to his wife or he'll lose her forever. 
So as they went up, Orpheus was just so afraid that Eurydice wasn't with him and he had to look back to his wife.Because he didn't believe Eurydice was behind him. And there, he lost her forever indeed.Source(s):my senior high school notes from mythology class. :D
