In 
Greek mythology, 
Menippe and 
Metioche were daughters of 
Orion.  They were extremely beautiful and talented, equals of 
Aphrodite and 
Artemis.  Their homeland, 
Aonia[?], at the base of 
Mt. Helicon[?] was struck by a plague and the sisters volunteered to be sacrificed to end it.  As a reward, they were placed among the stars.
