Lugh/Lug

The god appearing most frequently in the tales is Lugh. He is evidently a residual of the earlier, more widespread god Lugus, whose diffusion in Celtic religion is apparent from the number of place names in which his name appears, occurring across the Celtic world. The most famous of these are the cities of Lugdunum (the modern French city of Lyon), Lugdunum Batavorum (the modern city of Katwijk, 10 kilometers to the west of Leiden in the Netherlands) and Lucus Augusti or Λοuκος Λuγούστον (the modern Galician city of Lugo). Lug is described in the Celtic myths as the last to be added to the list of deities. In Ireland a festival called the Lughnasa (Modern Irish lúnasa) was held in his honour.

The Morrígan

The Morrígan was a tripartite battle goddess of the Celts of Ancient Ireland. She was known as the Morrígan, but the different sections she was divided into were also referred to as Nemhain, Macha, and Badb (among other, less common names), with each representing different aspects of combat. She is most commonly known for her involvement in the Táin Bó Cúailnge.

The Dagda

The leader of the gods for the Irish pantheon appears to have been the Dagda. The Dagda was the figure after which male humans and other gods were based due to his embodiment of the ideal Irish traits. Celtic gods were also considered to be a clan due to their lack of specialization and unknown origins. The particular character of the Dagda describes him as a figure of burlesque lampoonery in Irish mythology, and some authors even conclude that he was trusted to be benevolent enough to tolerate jokes at his own expense.
Irish tales depict the Dagda as a figure of power, armed with a spear. In Dorset there is a famous outline of an ithyphallic giant known as the Cerne Abbas Giant with a club cut into the chalky soil. While this was probably produced in relatively modern times (English Civil War era), it was long thought to be a representation of the Dagda. This has been called into question by recent studies which show that there may have been a representation of what looks like a large drapery hanging from the horizontal arm of the figure, leading to suspicion that this figure actually represents Hercules (Heracles), with the skin of the Nemean Lion over his arm and carrying the club he used to kill it. In Gaul, it is speculated that the Dagda is associated with Sucellos, the striker, equipped with a hammer and cup.

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.
