With the Big Three, the Greeks viewed them as the three sons of Kronos, and the most powerful of his children. However, at Camp Jupiter they never mention a Big Three. They do however hold Jupiter, Mars, and Bellona in the highest respect, with those three gods having temples at the highest points of temple hill. As far as the Great Prophecy goes, it was spoken by an Oracle, a Greek concept. There was no risk of a Roman demigod reaching 16 as the prophecy didn't apply to them.

Now that I mention it, the Great Prophecy makes no sense. It mentions a half-blood of the eldest gods, but that could refer to any child of the original Olympians. Why didn't Zeus freak out when Katie Gardner started getting close to 16? I mean out of the six original Olympians, Zeus was the youngest. What about Demeter?
