Diarmait mac Cerbaill

From Wikipedia, the free encyclopedia

Diarmait mac Cerbaill (died c. 565) was King of Tara or High King of Ireland. According to traditions, he was the last High King to follow the pagan rituals of inauguration. While many later stories were attached to Diarmait, he was a historical ruler and his descendants were of great significance in Medieval Ireland.

[edit] Historical Background

Diarmait was the son of Fergus Cerrbél mac Conaill Cremthainne (Fergus Crooked Mouth) and a great-grandson of Niall of the Nine Hostages from whom the Uí Néill took their name. Diarmait himself was the apical ancestor of the Southern Uí Néill whose kindreds took their names from Diarmait's sons:

The Annals of Tigernach record that Diarmait celebrated the Feast of Tara, his inauguration as King, in 558 or 560. The previous King of Tara, according to the earliest lists, was Óengarb, an epithet meaning "extremely rough", presumed to refer to Diarmait's kinsman Tuathal Maelgarb. What followed the inauguration was "a surprisingly unpropitious reign for so famous a king.[1]"

Diarmait was defeated at the battle of Cúl Dreimne (near Ben Bulben in modern County Sligo) in 560 or 561. This was the "Battle of the Books", supposedly the result of Diarmait's judgement in a dispute between Columba and Finnian of Moville. Columba, it is said, had secretly copied a book beloning to Finnian, and the matter of ownership of the copy had come to be settled by Diarmait, who adjudged in Finnian's favour, reportedly saying "[t]o every cow its calf and to every book its copy." Columba sought support from his kinsmen among the Cenél Conaill and the Cenél nEógain of the northern Uí Néill who went to war with Diarmait. This is a late tradition, and annalistic accounts claim that the battle was fought over Diarmait's killing of Diarmait of Curnán, son of the King of Connacht who was under Columba's protection.[2]

Following this defeat, Diarmait lost the battle of Cúil Uinsen to Áed mac Brénainn, king of Tethbae in Leinster. Diarmait played no part in the great Uí Néill victory of Móin Daire Lothair in 563. He was killed in 565, at Ráith Bec in Mag Line (Moylinny, near Larne) in Ulster by Áed Dub mac Suibni, king of the cruithne.[3]

According to the later Irish historians, Diarmait was followed as King of Tara by Domnall Ilchegalch and Forguss, sons of Muirchertach mac Ercae, of the Cenél nEógain. More contemporary sources suggest that the Kingship of Tara all but disappeared in the years following Diarmait's death, and that it was not until the time of Domnall mac Áedo, or perhaps of Fiachnae mac Báetáin, that there was a High King of Ireland again.[4]

[edit] Saints and Druids

Adomnán of Iona, writing less than 150 years after Diarmait's death, describes him as "ordained by God's will as king of all Ireland." Given that the annals say that Diarmait celebrated the Feast of Tara, the pagan inauguration ceremony, Adomnán's words represent his view of kingship rather than the reality of Diarmait's life.[5] Most traditions portray Diarmait as in conflict with saints and holy men, notably Columba. A later poet has Diarmait say "Woe to him that contends with the clergy of the churches".[6]

Supernatural features in Diarmait's reign are not limited to prose and verse works or to lives of saints. Even the Irish annals include a reference to druid fences being created at the battle of Cúl Dreimne. The main subject for later writers and poets was not Diarmait's life, but his death.

Diarmait was told by Bec mac Dé that Áed Dub, Diarmait's foster-son, would be his killer. Accordingly, Diarmait banished Áed Dub.[7] Saint Ruadán gave the prophecy that Diarmait would be killed by the roof-beam of his hall at Tara. Diarmait had the beam cast into the sea. Diarmait then asked his druids to find the manner of his death, and they foretold that he would die of slaughter, drowning and burning, and that the signs of his death would be a shirt grown from a single seed of flax and a mantle of wool from a single sheep, ale brewed from one seed of corn, and bacon from a sow which had never farrowed. On a circuit of Ireland, Diarmait comes to the hall of Banbán at Ráith Bec, and there the fate of which he was warned comes to pass. The roof beam of Tara has been recovered from the sea by Banbán and set in his hall, the shirt and mantle and ale and bacon are duly produced for Diarmait. Diarmait goes to leave Banbán's hall, but Áed Dub, waiting at the door, strikes him down and sets fire to the hall. Diarmait crawls into an ale vat to escape the flames and is duly killed by the falling roof beam. Thus, all the prophecies are fulfilled.[8]

Lik tales are told of Muirchertach mac Ercae and Adomnán records that Columba prophecied a similar death, by wounding, falling and drowning, for Áed Dub.[9]
