Greek Mythology

Greek Mythology (ギリシャ神話) is the mythology of the ancient Greeks. A large part of Roman mythology is derived from Greek mythology and it forms the foundation of what is known as Classical Mythology.

Principles
As a mythology with a pantheon of gods, it operates similarly with Norse Mythology. As gods of polytheistic religion, they have emotions similar to those of humans such as love, justice, fear, and jealousy, and having doubts and failures like any one else. These gods aren't perfect, and such as when combined in a single group, complemented each other's weaknesses, creating a single flexible system, a sturdy defense system that could not be overcome by any foe.

Like a number of other mythologies, the primary deities of Greek mythology are a younger generation of gods who fought against an older, more chaotic generation of gods, in this case the Titans, conquering them and taking their place.

Background
Though Greek mythology-based Magic has yet to appear in the main story of Toaru Majutsu no Index, it has been mentioned as a potential magical format, and as one of the many religions and mythologies which have caused Phases to be created over the world.
