c. 68/63–41 BCE
Arsinoe IV was a Ptolemaic princess, a younger sister of Cleopatra VII, who became a rival claimant during the Alexandrian War. In 48 BCE Julius Caesar arrived in Egypt amid a civil conflict between Cleopatra and their brother Ptolemy XIII. Arsinoe escaped from the royal quarter controlled by Caesar and joined the opposing Egyptian forces, where she was proclaimed queen. Her position gave the anti-Caesarian side a member of the dynasty around whom resistance could be organised.
Arsinoe soon became entangled in disputes among her own commanders, including the general Achillas and the eunuch Ganymedes. After Caesar’s forces prevailed and Ptolemy XIII died, Arsinoe was taken to Rome and displayed in Caesar’s triumph, but her life was spared. She later lived in sanctuary at the Temple of Artemis at Ephesus. In 41 or 40 BCE, at Cleopatra’s request and with Mark Antony’s authority, Arsinoe was executed there, removing a surviving dynastic rival to Cleopatra’s rule.
In Simon Turney’s Marius’ Mules XII, Caesar arrives in Egypt after Pompey’s murder and becomes entangled in the struggle between Cleopatra and Ptolemy XIII. In Margaret George’s The Memoirs of Cleopatra, Told as Cleopatra VII’s own memoir, the novel follows the last Ptolemaic queen from childhood in an unstable royal household to her struggle for sole control of Egypt.
