In short: Arsinoe IV, the younger sister of Cleopatra VII, once commanded the Egyptian army and forced Julius Caesar to flee for his life. Despite her military success, she was eventually betrayed, paraded in a Roman triumph, and murdered in a sacred temple at the behest of her own sister.

Arsinoe IV was the daughter of Ptolemy XII Auletes and a key figure in the power struggles of the late Ptolemaic dynasty. When her father died in 51 BC, he left the throne to his eldest children, Cleopatra VII and Ptolemy XIII. However, after Cleopatra was ousted, Julius Caesar arrived in Alexandria in 48 BC and sided with her. Arsinoe escaped the palace, declared herself queen, and took command of the Egyptian army alongside her mentor, the eunuch Ganymedes. Her forces successfully trapped Caesar in the city, nearly securing a victory that would have changed the course of Roman history.

The conflict turned when Egyptian officers negotiated to exchange Arsinoe for her brother, Ptolemy XIII, to secure peace. Following the Roman victory, Arsinoe was taken to Rome in 46 BC, where she was paraded in Caesar's triumph. While she was granted sanctuary at the Temple of Artemis in Ephesus, her freedom was short-lived. Cleopatra, viewing her sister as a persistent threat to her authority, pressured Mark Antony to order Arsinoe's execution in 41 BC. The murder, carried out on the temple steps, was a profound violation of sanctuary that shocked the Roman world.

For years, researchers debated whether a skeleton found in an octagonal tomb at Ephesus belonged to the queen. Archaeologist Hilke Thür hypothesized in the 1990s that the remains were Arsinoe's, citing the tomb's shape and the age of the individual. However, these claims faced significant skepticism from scholars like Mary Beard, who noted the lack of inscriptions and the unavailability of the skull for analysis. A definitive 2025 study by the University of Vienna finally resolved the mystery: DNA analysis of the cranium and femur confirmed the remains were those of a male, proving the tomb did not belong to Arsinoe IV.
