Mark Antony and Cleopatra are among the most famous pairs of lovers from the ancient world. Following their defeat at the Battle of Actium in 31 B.C., they took their final refuge from the victorious Octavian in Egypt, where Cleopatra was queen. In 30 B.C., Egypt was invaded, and following the Battle of Alexandria, the two lovers lost their lives, under circumstances that most historians believe was suicide (though some maintain it was murder).
Nevertheless, it seems even death could not separate them, as historic sources record that they were laid to rest together. The location of their tomb, however, has never been found. It is a historical mystery that has endured over nearly two millennia.
