Arsinoe IV of Egypt

Arsinoë IV was the fourth of six children and the youngest daughter of Ptolemy XII Auletes. Queen and co-ruler of Ptolemaic Egypt with her brother Ptolemy XIII from 48 BC – 47 BC, she was one of the last members of the Ptolemaic dynasty of ancient Egypt. Arsinoë IV was also the half sister of Cleopatra VII. For her role in conducting the siege of Alexandria against her sister Cleopatra, Arsinoë was taken as a prisoner of war to Rome by the Roman triumvir Julius Caesar following the defeat of Ptolemy XIII in the Battle of the Nile. Arsinoë was then exiled to the Temple of Artemis at Ephesus in Roman Anatolia, but she was executed there by orders of triumvir Mark Antony in 41 BC at the behest of his lover Cleopatra VII.
