Well, the Greeks didn't have the Sybillian books and Rome did. (And Octavian the augar wasn't greek either). They just had their oracle which told them prophecies sometimes, and it said that Athena only picked one or two a GENERATION to go on the quest. I don't get thatthinkg about being on Circe's island but Reyna had been about to explain when Leo fired ballistae.
