Tuireann, from Ireland: what it is and what people believe

An Irish legendary father whose three sons, born to Danu or to Brigid, killed Cian, the father of Lugh, and were sent out as an éraic, a fine of recompense, on the quest told in one of Erin's three sorrowful tales. Once Lugh's revenge was complete, Tuireann died of grief at their graves; many read him as a god of the sky.

What it is

Tuireann belongs to the mythic history of Ireland. His part is a father's part: three boys were born to him, Brian, Iuchar and Iucharba, and their mother is given as Danu in one telling, Brigid in another. Those sons killed Cian, the father of Lugh. Blood-price followed. The fine of recompense, the éraic, sent the three out on a quest that fills the tale Oidheadh Chlainne Tuireann, one of Erin's three sorrowful tales. Lugh's revenge, once fully carried out, left none of the sons alive, and their father died of grief at their graves. Because his name and imagery resemble those of the Gaulish god Taranis, Tuireann is thought to have been a deity of the sky.

Where it comes from

The tale of the sons, Oidheadh Chlainne Tuireann, is glossed in English as The Tragedy of the Sons of Tuireann, and holds a place among Erin's three sorrowful tales. Tuireann himself stands as a figure of legend, not a man of record. Attempts were made to anchor him: several passages of Lebor Gabála Érenn declare him identical with Delbáeth mac Ogma, to whom the same three sons are assigned. Likeness of name and of imagery has also joined him to Taranis, a deity of the Gauls, and on that ground many take him for a god of the sky. Early shapes of the name are Tuirenn and Tuirill Biccreo.

What people believe

These stories take for granted that a killing can be paid for. The price is an éraic, a fine of recompense, and the tale has Lugh impose its terms: a quest that carries his three offenders to their deaths. The figures themselves are more than mortal. Tuireann is read as a god of the sky, on the strength of his name and imagery matching those of the Gaulish Taranis, and the mother of his children is given as Danu, or else Brigid.

How scholars and sceptics see it

Two lines of study meet on this figure. Comparison of names and of imagery ties Tuireann to Taranis, a deity of Gaul, and on that basis he is judged to have been a god of the sky. Textual work runs a second path: different passages of Lebor Gabála Érenn state that Tuireann and Delbáeth mac Ogma are one and the same, and Delbáeth receives the same three sons there, so the tradition keeps more than one identity for him. His very existence as a man is a matter of doubt; what stands clear is his role in the tale.

Compare and confuse

Conflation is the main trap. In parts of Lebor Gabála Érenn, Tuireann and Delbáeth mac Ogma are declared one and the same, and that Delbáeth is given the same three sons. The name also varies between texts, appearing as Tuirenn and as Tuirill Biccreo, and the family's tale is known by the father's name rather than the sons'.

Questions people ask about Tuireann

Who is Tuireann?

A father figure of Irish mythology. Three sons, Brian, Iuchar and Iucharba, were born to him by Danu or by Brigid, and those sons killed Cian, the father of Lugh. On the evidence of his name, many read him as a sky god.

Where does his story come from?

From the legendary history of Ireland. The sons' quest is told in Oidheadh Chlainne Tuireann, one of Erin's three sorrowful tales, while Lebor Gabála Érenn takes up the question of who he was.

Why is he thought to be a god?

Because his name and imagery match those of Taranis, a deity of Gaul. On that likeness, readers take Tuireann for a god of the sky rather than a mortal father alone.

What is an éraic?

A fine of recompense. In the story, the killing of Cian was answered with an éraic that sent Tuireann's three sons on a quest, from which none returned; their father then died of grief at their graves.

Is he the same as Delbáeth mac Ogma?

Several passages of Lebor Gabála Érenn say the two are one, and they assign Delbáeth the same three sons as well. The tradition therefore carries two names and one father for this family.
