Artemis in Ephesus, against her older hostile sister Cleopatra and perhaps even wanted to make her new queen of Egypt. When Cleopatra had won the favour of Mark Antony after the victory of the Caesarians she used the power of the triumvir to take revenge on her enemies (41 BC). Not only Arsinoe IV, but also Serapion were among her victims. He had taken refuge in Tyre but Antony ordered that he had to be handed over to Cleopatra. Some scholars suggest it's very probable that she had him executed. Notes References Michael Grant, Cleopatra, 1972 and 1974, German edition 1998, pp. 102, 146, 172.
