Orpheus

While walking among her people, at her wedding to Orpheus, Eurydice was set upon by a satyr. In her efforts to escape the satyr, Eurydice fell into a nest of vipers and suffered a fatal bite on her heel. Her body was discovered by Orpheus; overcome with grief, he played such sad and mournful songs that all the nymphs and gods wept. On their advice, Orpheus travelled to the underworld. His music softened the hearts of Hades and Persephone (King and Queen of the Underworld), who agreed to allow Eurydice to return with him to Earth, but only on condition that he should walk in front of her and not look back until they had both reached the upper world. Orpheus set off, with Eurydice following. But as soon as he reached the upper world, Orpheus turned to look at his wife, forgetting that they both needed to be in the upper world. She vanished once more – this time forever.

In the Bible, Lot's wife made the same mistake. Her fate was possibly even worse than Eurydice's: she was turned into a pillar of salt.
