read the below quote from Betty Bonham Lies retelling of the myth of Orpheus and Eurydice

"Orpheus loved Eurydice more than anything in the world. He could not imagine living without her. When she died, he felt like his heart had been ripped out of his chest. He couldn't bear the thought of never seeing her again. So, he made the dangerous journey to the underworld to beg Hades to return Eurydice to him. With his music, Orpheus swayed the hearts of Hades and Persephone, and they agreed to let Eurydice go. However, there was one condition: Orpheus must not look back at Eurydice until they had reached the world above. As they climbed the steep path, Orpheus couldn't resist the urge to look back and make sure she was still there. But in that instant, Eurydice vanished forever, swallowed back into the underworld."
