Merope
One of the Pleiades; a daughter of Atlas and Pleïone.
Of all the Pleiades, only Merope had a mortal husband or lover: Sisyphus, king of Corinth. Merope was the mother of Glaucus, Ornytion, Thersander and Almus.
On her husband's instructions, Merope did not perform the proper funeral rites for him at his death. Hades had no choice but to send him back to the surface of the living, on the condition that he returned after making proper arrangements with the customary rites. Of course, Sisyphus did no such thing. Sisyphus did not return to the Underworld until he died of old age.
When the Pleiades were in the night sky as stars, Merope was the faintest star. Hyginus said that she blushed, because she had married a mortal. Each of her other sisters had an affair with the gods.
