Answer
Ptolemaios Kaisar, also known as Caesarion, was the son of Julius Caesar and Cleopatra VII. His Greek name, Ptolemaios, reflects his lineage as a member of the Ptolemaic dynasty of Egypt, while Kaisar, the Latinized form of Caesar, acknowledges his Roman heritage. Caesarion's dual naming symbolizes the complex political and cultural dynamics of the Mediterranean world during the late Roman Republic.
