Great Prophecy

The Great Prophecy was a predictions made by the Oracle of Delphi that foretold the rise or fall of Olympus by a child of the Big Three.

The Great Prophecy
The First Great Prophecy is a prophecy given by the Oracle seventy years ago. Around World War II, when the sons of Zeus (America), Poseidon (Great Britain and Soviet Union), and Hades (Nazi Germany, Fascist Italy, and Imperial Japan) fought each other, the Oracle foretold of a future event that would end their affairs with mortal women for the next seventy years. The prophecy is revealed in The Last Olympian:


 * A half-blood of the eldest gods
 * shall reach sixteen against all odds
 * And see the world in endless sleep
 * The hero's soul, cursed blade shall reap
 * A single choice shall end his days
 * Olympus to preserve or raze

Unraveling the Prophecy

 * 1) Percy is a half-blood child of Poseidon, one of the eldest gods.
 * 2) Percy turns 16 at the climax of the Battle of Manhattan, despite all his near death experiences.
 * 3) Morpheus (the god of dreams/sleep) put every mortal in Manhattan to sleep.
 * 4) "The hero" does not refer to Percy, but to Luke, whose soul was reaped by Annabeth's knife, cursed because of Luke's broken promise to Annabeth.
 * 5) Percy's choice was to give Luke the knife allowing Luke to kill himself and therefore killing Kronos ended his days.
 * 6) Olympus was preserved because Percy chose to give Luke Annabeth's knife so that Luke could destroy Kronos by slicing his Achilles heel (under his arm).

The Prophecy of Seven
After the completion of the first Great Prophecy, Rachel Elizabeth Dare took on the spirit of the Oracle of Delphi and spoke a new prophecy, which was declared as the second Great Prophecy. This prophecy would later be known as the Prophecy of Seven as the Romans called it.

"Seven half-bloods shall answer the call,

to storm or fire the world must fall.

An oath to keep with a final breath,

And foes bear arms to the Doors of Death."

''1. Piper, Leo, Jason, Percy, Annabeth, Frank and Hazel are the seven half-bloods''
