Mythology of Ireland

The oldest body of myths stemming from the Heroic Age is found only from the early medieval period of Ireland. As Christianity began to take over, the gods and goodness were slowly eliminated as such from the culture. What has survived includes material dealing with the Tuatha Dé Danann and theFomorians, which forms the basis for the text Cath Maige Tuireadh (the Battle of Mag Tuireadh), as well as portions of the history-focused Lebor Gabála Érenn (the Book of Invasions). The Tuatha Dé represent the functions of human society such as kingship, crafts and war, while the Fomorians represent chaos and wild nature.
