Cleopatra was a sex-crazed roman-egyptian witchqueen, who disapeared mysteriously under the roman civil war, who broke out after her lover, Julius Caesar, was killed by assasins in his own senate.
Cleopatras faction lost the war eventually.
I like to think that she tried to blend in with the peasants under her escape, and got captured by the legionaires, taken for a common woman.
Nothing could be more becoming for her than a largescale gangrape, followed up with a lifelong sexslavery in the brothels of Rome.
