Yes though that can be considered a hint. It is shown in the Son of Neptune that the Romans knew more about the Greeks than the Greeks did about the Romans. For instance Reyna knew about the Civil War and Octavian suspected the existence of Greeks too. The Greeks had never heard of the Romans. The Romans knew about the Greek demigods, they just didn't know about the existence of Camp Half-Blood.
