The slave girl is an enslaved person who plays the harp for Cleopatra in Act IV. When Cleopatra expresses interest in learning to play, the girl’s teacher, an old musician, informs her that the undertaking requires learning the philosophy of Pythagoras and will take years to master. The enslaved girl, in contrast, has not had a proper musical education and only “learns as a dog learns.” Cleopatra retorts that the enslaved girl plays more beautifully than her teacher despite her rudimentary education. Cleopatra’s admiration for the enslaved girl’s practical skills over the old musician’s structured approach to music education shows that she has internalized Caesar’s pragmatism.
