For decades, scholars have believed that a skeleton discovered by archaeologists in the ruins of the ancient city of Ephesos in 1929 belonged to Cleopatra’s half-sister, Arsinoe IV. However, recent analysis reveals the remains actually belonged to a young boy, overturning the long-held speculation.

By the 1990s, researchers proposed that the unusual burial might have belonged to Cleopatra’s half-sister, who some believed was executed in Ephesus in 41 BCE at the demand of Mark Antony.

A mystery dating back nearly a century about a skull believed to belong to Cleopatra's murdered half-sister has been solved using modern DNA analysis and radiocarbon dating.

Austrian archaeologist Josef Keil and his team discovered a sarcophagus completely filled with water in the ruins of the ancient “Octagon,” a splendid building on the main street of Ephesus (Turkey).

Scientists have learned that a skull that long-believed to be that of Cleopatra’s sister Arsinoë IV actually belonged to a young boy. A team from the University of Vienna and Austrian Academy of Sciences analyzed the skull and found that the boy was likely between 11 and 14-years-old and suffered from an unknown developmental disorder.
