Final answer:
Antony speaking to Caesar from his right side likely indicated respect and honor, aligned with Roman cultural norms. Practical reasons such as Caesar's partial hearing loss may have also played a role.
Step-by-step explanation:
The reason Antony would have to speak to Caesar from his right side is not explicitly mentioned in the given passage. However, historically, it is essential to note that in Roman culture, the 'right side' was often considered a place of favor and honor. This cultural perspective might imply that Antony, being a close ally and a loyal subordinate of Caesar, would naturally approach Caesar from this privileged position to show respect and to ensure that he is heard by the most powerful man in Rome during his time. It is also a known fact that Caesar had some degree of hearing loss in his left ear according to historical accounts, so Antony speaking on Caesar's right side could also be practical to ensure he was heard clearly.
The context provided focuses on the political dynamics and the power struggles in Ancient Rome during the era of Caesar, Mark Antony, and Octavian. It touches on the formation of the Second Triumvirate and the consolidation of power following Caesar's assassination, the alliance and eventual conflict between Mark Antony and Octavian, and the historical accounts by Plutarch and Cicero, which give us insight into the lives and actions of these key figures of Roman history.
