What is "charmion"

Laverie Vallee née Cooper (July 18, 1875 – February 6, 1949), best known by her stage name Charmion, was an American vaudeville trapeze artist and strongwoman whose well-publicized suggestive performance was captured on film in 1901.

Charmion , alternatively Charmian, was a trusted servant and advisor to the historical Cleopatra VII of Egypt.
