The celebrations lasted several days. The key ceremony took place in the gymnasion, the usual location for coronations in Alexandria. Like actors on a stage, Antonius and Kleopatra and her four children - three of whom were also Antonius’ children -
performed on an elevated dais before the royal household, the royal guard and members of the Alexandrian citizenry. Kleopatra and her eldest son Ptolemaios XV Caesar (‘Caesarion’), with whom she shared the Ptolemaic kingship, were proclaimed Queen of Kings and King of Kings of the enormous empire outlined above. Antonius’ children by Kleopatra - Alexandros Helios, Kleopatra Selene, Ptolemaios Philadelphos - received lesser, albeit still magnificent royal titles. Kleopatra was dressed as Isis, Antonius presumably as Dionysos; Alexandros Helios wore the attire of an Iranian king, and Ptolemaios Philopator the generic royal dress of a Hellenistic king. The only participant, who was not awarded royal honours, was Antonius, the Roman.
