why does hades at first agree to return eurydice to orpheus
Orpheus and Eurydice Orpheus played his lyre, melting even Hades' cold heart. Hades told Orpheus that he could take Eurydice with him but under one condition; Eurydice would follow him while walking out to the light from the caves of the Underworld, but he should not look at her before coming out to the light because he would lose her forever and ever. If Orpheus was patient enough he would have Eurydice as a normal woman again by his side.
