As a mythology and literature expert, I can provide you with an explanation of why Eurydice went to the underworld according to Greek mythology.

Eurydice was a nymph and the wife of Orpheus, a legendary musician. The story of Eurydice's descent to the underworld is a tragic one. According to the most common version of the myth, Eurydice was bitten by a venomous snake and died as a result. In her death, she was taken to the underworld, which in Greek mythology is ruled by Hades and is the place where the souls of the dead reside.

Orpheus, in his deep love and grief, decided to venture into the underworld to bring Eurydice back to life. His music was so beautiful and moving that it softened the hearts of both Hades and Persephone, the queen of the underworld. They agreed to allow Eurydice to return to the world of the living on one condition: Orpheus must lead the way out of the underworld and Eurydice must follow behind him, and he must not look back at her until they had both reached the surface.

However, as they were nearing the exit, Orpheus, in his anxiety and doubt, looked back to see if Eurydice was indeed following him, which was the one thing he was told not to do. As a result, Eurydice was pulled back into the underworld, and Orpheus lost her forever.
