Orpheus and Eurydice

The most famous story in which Orpheus figures is that of his wife Eurydice (also known as Agriope). While walking among her people, the Cicones, in tall grass at her wedding, Eurydice was set upon by a satyr. In her efforts to escape the satyr, Eurydice fell into a nest of vipers and she suffered a fatal bite on her heel. Her body was discovered by Orpheus who, overcome with grief, played such sad and mournful songs that all the nymphs and gods wept. On their advice, Orpheus traveled to the underworld and by his music softened the hearts of Hades and Persephone (he was the only person ever to do so), who agreed to allow Eurydice to return with him to earth on one condition: he should walk in front of her and not look back until they both had reached the upper world. He set off with Eurydice following, and, in his anxiety, as soon as he reached the upper world, he turned to look at her, forgetting that both needed to be in the upper world, and she vanished for the second time, but now forever.

In our opinion the Myth of Orpheus and Eurydice is a quite representation of the dichotomy between the Resistance and Weakness: the inability of Orpheus to respect the Hades' condition.
