I have read with great attention the last articles of Heraklia and Lucilia about Cleopatra VII and I have seen that them speak togheter also of Cesarion. Perhaps it was the son of Caius Iulius Caesar anyway he has never become a roman citizen because until the conflict between Antonius et Octavianus he was as soon as the mother an enemy of senatus populusque romanus. Naturally nothing of personal motivation but for economical motivations. Rome wants the aegyptian wealth and Cesarion and Cleopatra didn't have any chance to mantein their potestas. Also Marcus Antonius cannot change the voluntas of roman imperialism. The gladium et aquila romana kill not two pharaones but the most ancient reign of the world.
