Cleopatra Selene was the only daughter of Greek Ptolemaic Queen Cleopatra VII of Egypt and Roman Triumvir Mark Antony. In the Donations of Antioch and of Alexandria, she was made ruler of Cyrenaica and Libya. After Antony and Cleopatra's defeat at Actium and their suicides in Egypt in 30 BC, Selene and her brothers were brought to Rome and placed in the household of Octavian's sister, Octavia the Younger, a former wife of her father.
