Sculpture depicting Alessandro Helios and Cleopatra Selene, twin sons of Cleopatra and Marc Antony
Of the four children by Cleopatra only the female managed to lead a relatively normal existence, while the males were united by a tragic destiny.
The cause of their misfortune was Octavian Augustus, political genius but a treacherous, hypocritical and petty man, ready to do anything in order not to endanger his own power.
To be safe, the princeps he first killed Caesarion, twelve years old son of Caesar, then almost certainly also Alessandro Helios and Ptolemy Filadelfo , sons of Marco Antonio, disappeared into thin air in Rome still children.
It fared better than Alexander's twin, Cleopatra Selene, which she took care of Octavia, second wife of Antonio.
When she became an adult, Octavian gave her in marriage to Juba II , king of Numidia, which consequently made the woman queen of Numidia and Mauretania.
Perhaps three children were born from the marriage, but there is absolute certainty only of the fate of Ptolemy, who reigned over Mauretania until 40 AD, when he was killed by Caligula, which thus ended the long and glorious Ptolemaic dynasty.
Cleopatra Selene, daughter of Cleopatra, was therefore the last woman of the Ptolemies to reign.
