Ptolemy XII Auletes
Caesar was either horrified, or pretended to be horrified, at the murder of Pompey, and wept for his one-time ally and son-in-law. In an effort to mitigate the damage done to Rome's government and to Caesar's reputation, he planned to pardon all former Pompeians who surrendered to his forces, and the crown jewel of that would have been to pardon Pompey, which was now impossible. He demanded the money Ptolemy's father Ptolemy XII Auletes had been lent by Rome and agreed to settle the dispute between Ptolemy and his sister and co-regent Cleopatra VII. Caesar chose to favor Cleopatra over her brother.
