The “Arab mistress Messalina” never existed as a single person. She is a ghost, a composite of Roman scandal and Orientalist myth. Whether in ancient Rome or the medieval Arab court, the specter of Messalina has always been used to demonize powerful women. To invoke her name alongside “Arab” is not to identify a real figure, but to perpetuate a centuries-old fear of the woman who dares to rule through both desire and intellect.
