CLEOPATRA

In 41 BC, Mark Antony, one of the triumvirs who ruled Rome in the power vacuum following Caesar's death, summoned Cleopatra to meet him in Tarsus to answer questions about her loyalty. Cleopatra arrived in great state, and so charmed Antony that he chose to spend the winter of 41 BC–40 BC with her in Alexandria.

To safeguard herself and Caesarion, she had Antony order the death of her sister Arsinoe, who was living at the temple of Artemis in Ephesus, which was under Roman control. The execution was carried out in 41 BC on the steps of the temple, and this violation of temple sanctuary scandalised Rome.[15]

On 25 December 40 BC, Cleopatra gave birth to twin children fathered by Antony, Alexander Helios and Cleopatra Selene II. Four years later, Antony visited Alexandria again en route to make war with the Parthians. He renewed his relationship with Cleopatra, and from this point on Alexandria would be his home. He married Cleopatra according to the Egyptian rite (a letter quoted in Suetonius suggests this), although he was at the time married to Octavia Minor, sister of his fellow triumvir Octavian. He and Cleopatra had another child, Ptolemy Philadelphus
