Orpheus and Lot's Wife

... both looked back when they had been expressly told not to.

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. Lot set off, with Eurydice following. But as soon as Orpheus reached the upper world, he turned to look at his wife, forgetting that they both needed to be in the upper world. She vanished for the second time – but now forever.

Lot invited two angels to spend the night at his home. As dawn was breaking, the angels urged Lot to get his family and flee; unknown to Lot and his family, the city of Sodom was about to be destroyed. The angels urged them to flee for their lives, not to look behind them, nor stop anywhere in the plain; to flee to the hills, lest they be swept away. Lot objected to the idea of fleeing to the hills, and requested safe haven at a little town nearby. The request was granted. But Lot's wife, travelling behind her husband, looked back, and was turned into a pillar of salt.
