The Tuatha Dé Danann

In Irish and Celtic mythology the Tuatha Dé Danann were a supernatural race who were known to interact with and form relationships with humans.  They had a reputation for being adept in the sciences, arts, magic and necromancy. Their name translates as the people of the goddess Dana or Danu and they are seen as being the main gods of Ireland before the arrival of Christianity.   Along with the Fir Bolg they were the descendents of Nemed, who ruled the third wave of invaders of Ireland and was reputedly descended from the Biblical Noah. They were believed to have come from Falias, Gorias, Murias and Finias which were four cities  located somewhere to the north of Ireland. They brought with them four magical treasures; the Dagda’s Cauldron, the Spear of Lugh, The Stone of Fal, and the Sword of Light of Nuada.

Each individual of the Tuatha Dé Danann was seen as being a representation of certain aspects of the natural world and some of them were associated with more than one.  Some individuals were also known by other names which may vary from region to region. The Tuatha Dé Danann were the traditional enemies of the Fomorians who appear to represent the dark destructive forces of nature.  They were personifications of drought, pestilence, chaos, darkness and death, whereas the Tuatha Dé Danann were gods of civilisation and growth. 

Christian Records

It was the Christian monks that recorded and wrote down Irish mythology and in doing so altered and rewrote some of it to a degree.  They often saw the Tuath Dé Danann as kings, queens and heroes from a bygone era and credited them with having supernatural powers. Another view was that they were fallen angels being neither good or evil. Other medieval writers  saw them as being gods or spirits because some characters are found in tales that are from different times often separated by centuries. This lent to the belief that they were divine or immortal beings. For example, Manannán mac, Aengus, Morrígan and Lugh all appear in tales from different eras which many see as supporting the idea of their immortality.

The Lebor Gabála Érenn

The Lebor Gabála Érenn  is a collection of poetry and writing collected in the Middle Ages.  It claims to tell the history and origin of the Irish and Ireland up to the time it was written.  Many versions exist but the earliest were believed to have been written in the 11th century. According to this work the Tuatha Dé Danann arrived in Ireland in ships bringing,  “dark clouds”.  They were said to have landed on the mountains of Connachta bringing three days and nights of darkness.  Another later version says that they burnt their ships on arrival so there was no way they could go back. The smoke from the ships filled the air and was the cause of the dark clouds and darkness.  

King Nuada

Their leader was King Nuada who led them in the First Battle of Magh Tuireadh where they defeated the Fir Bolg, the native inhabitants of Ireland.  Although they won, King Nuada lost an arm fighting Sreng, the Fir Bolg champion. Despite this Sreng and his three hundred followers were losing the battle and facing defeat  vowed to fight to the death. The Tuatha Dé Danann were so impressed with their valor and fighting ability they offered them a one fifth of Ireland if they pulled out of the fight.   This was agreed and they chose Connacht and the people there were said to be able to trace their ancestry from Sreng up to the 17th century.

However, Nuada had been badly wounded, losing an arm and this meant that he was no longer unblemished.  According to Tuatha Dé Danann tradition this meant he had to relinquish the kingship.   Bres, who was half-Fomorian became king and he demanded tribute from the Tuatha Dé and enslaved them.

Dian Cecht, a great healer, replaced the lost arm of Nuada with a fully functioning silver one which allowed him to take back the kingship.   Miach, the son of Dian Cecht was not satisfied with the replacement arm of Nuada and cast a spell saying which made flesh grow over the artificial silver arm in nine days and nine nights.  Jealous at the skill and success of his son Dian Cecht murdered his him.

Bres was forced to hand back the crown to Nuada and consulted with Elatha, his father who would have no part in any scheme to win back the kingship. Instead he advised him to seek help from Balor the king of the Fomorians.  Balor agreed to help Bres and from this came the Second Battle of Magh Tuireadh where the Tuatha Dé Danann fought the Fomorians led by Balor, who killed Nuada with his poisonous eye. Then the Tuatha Dé, champion, Lugh killed Balor and became king of the Tuatha Dé Danann.

The Invasion of the Milesians

The arrival of invaders to Ireland from what today is known as Galicia in  Portugal on the Iberian Peninsula brought further conflict. These invaders were believed to be Goidelic Celts, who were believed to be descendants of Míl Espáine and known as Milesians.

They met three of the Tuatha Dé Danann, goddesses;  Ériu, Banba and Fodla who requested them to name the island after them which is where the modern name Éire came from.  The husbands of these three goddesses were Mac Cuill, Mac Cecht and Mac Gréine who were kings of the Tuatha Dé Danann requested a three day  truce with the Milesians. During these three days the Milesian fleet would anchor nine waves distance from the coast. They agreed and complied with the truce but the Tuatha Dé Danann using magic summoned up a storm hoping to sink the enemy fleet or drive their ships out to sea.   

Tir na nOg

The Milesians called on their  poet Amergin for help. He calmed the seas with his poetry and they managed to safely land.  This resulted in a battle with the Tuatha Dé Danann at Tailtiu which the Milesians won. Amergin was tasked with dividing the island up between the two sides and in a stroke of genius gave the part above ground to his own folk while allotting the underground part to the Tuatha Dé Danann.  According to this tradition this is where the Tuatha Dé Danann took up their residence and is called Tir na nOg, which was a paradisaical place and often an island. It was one of the Celtic Otherworlds that could be reached in several ways including by entering ancient burial mounds or sidhe, going either over or under water, or by traveling through mist. In later times the Tuatha Dé Danann became known as the Aos Si or fairies.
