What does death symbolize in the play, Eurydice?

In this play, death does not symbolize a final separation. Instead, it symbolizes a passage from the world above to the underworld. Communication between the two worlds is possible, provided someone who is dead does not lose his or her memories. Eurydice's father writes to her from the underworld when she is in the world above, and Orpheus writes letters to Eurydice while she is in the underworld. This shows a bond of love is strong enough to surmount any barriers separating the world above from the underworld. When Eurydice and her father face a second death that promises a more permanent separation due to their losing their memories, they do so by choice.
