Cerball mac Dúnlainge (patronymic sometimes spelled Dúngaile, ) (died 888) was king of Ossory in south-east Ireland. The kingdom of Ossory (Osraige) occupied roughly the area of modern County Kilkenny and western County Laois and lay between the larger provincial kingdoms of Munster and Leinster.
Cerball came to prominence after the death of Fedelmid mac Crimthainn, King of Munster, in 847. Ossory had been subject for a period to the Eóganachta kings of Munster, but Feidlimid was succeeded by a series of weak kings who had to contend with Viking incursions on the coasts of Munster. As a result, Cerball was in a strong position and is said to have been the second most powerful king in Ireland in his later years.Byrne, Irish Kings, p. 266. Upon his death, he was succeeded by his brother Riagan mac Dúnlainge.
Kjarvalr Írakonungr (Old Norse: ; Modern Icelandic: ), a figure in the Norse sagas who appears as an ancestor of many prominent Icelandic families, is identified with Cerball.
Nature of the sources A large body of contemporary and near-contemporary material on early medieval Ireland has survived. From the titles of works mentioned in these sources, it is clear that a great deal of additional material has now been lost. The surviving materials usually exist in the form of much later copies, and it is only from comparison of the various texts that the original documents can be reconstructed.Hughes, Early Christian Ireland, is a general survey of the subject.
The Irish annals which document the ninth century are ultimately derived from the now-lost Chronicle of Ireland which was then being compiled in the midlands of Ireland. All annals include material derived from other sources, or added at a later date. None are complete, although the Annals of Ulster and the Annals of Inisfallen cover Cerball's lifetime. The Annals of Clonmacnoise survive only in an eccentric 17th-century English translation, and the Annals of Tigernach for this period are lost, although Dubhaltach Mac Fhirbhisigh's abbreviated copy known as the Chronicon Scotorum supplies much of the missing material. The Annals of the Four Masters are late, and include some material of doubtful origin. While the annals provide a considerable amount of information, they are generally terse, and most focus their attention on the doings of the Uí Néill, sometimes to the extent of omitting inconvenient events.Hughes, Early Christian Ireland, chapter 4, especially pp. 135–137; Charles-Edwards, Early Christian Ireland, p. xix.
A source which concentrates on Cerball's career is the Fragmentary Annals of Ireland, so called because only fragments remain of a seemingly longer work, these again copied by Mac Fhirbhisigh in the 17th century from a 15th-century manuscript. The fragment which deals with Cerball's lifetime ends in the early 870s, so that the last fifteen years of his life are missing. Joan Radner, editor and translator of the modern edition of the Fragmentary Annals, argues that these were compiled at the court of Cerball's great-great-grandson Donnchad mac Gilla Pátraic. Although called annals, these are closer to narrative history and are derived from a number of sources. The basic framework is from the Chronicle of Ireland, but to this has been added a variety of material whose source is unknown, perhaps including early sagas, which concerns Cerball. The Fragmentary Annals were intended to magnify Cerball's achievements, and to present his dealings with Vikings and Norse–Gaels in a favourable light.For the origins of the annals, see Radner, "Writing history", pp. 321–325. Comparable later works, more polished in style, include Cocad Gáedel re Gallaib (War of the Irish with the Foreigners), written around 1100 for Muirchertach Ua Briain, a great-grandson of Brian Bóruma, and Caithréim Chellacháin Chaisil (Deeds of Cellachán Caisil), written a generation later for Cormac Mac Cárthaig, a great-great-grandson of the eponymous Cellachán Caisil; Ó Corráin, "Afterthoughts", pp. 18–19 [page numbers after etext]; Radner, "Writing history", p. 323; Flanagan, "High-kings with opposition", pp. 916 & 919;
If the various annals are partisan, the remaining sources which concern Cerball are notably unreliable. Perhaps inspired by the Fragmentary Annals, which offer some positive views of Vikings and may have been popular in the Norse-Gael Dublin of the 11th century, many Icelandic genealogies include Cerball—Kjarvalr Írakonungr—as an ancestor.Byrne, p. 162; Ó Corrain, "Viking Ireland – Afterthoughts", pp. 17ff. Lastly, The Prophecy of Berchán, an 11th-century verse history of kings in Ireland and Scotland presented as a prophecy, may include Cerball.Hudson, Prophecy of Berchán, pp. 135–138.
A very large number of genealogies exist, along with geographical and legal texts. Of these last, the Frithfolad Muman, a document purporting to set out the obligations of the Kings of Munster to their allies, clients, and subjects is of interest as it sheds light on the position of Osraige within the provincial kingship of Munster.For discussion of the Frithfolad Muman see Byrne, Irish Kings, pp. 196–199 & Charles-Edwards, Early Christian Ireland, pp. 534–548.
Cerball's Ireland
A memory of the kingdom of Osraige survives today in the name and boundaries of the Roman Catholic Diocese of Ossory. The earliest recorded seat of the bishops was at Saighir, later moved to Aghaboe, and this appears to have been the principal church of the kingdom by the eighth century when the life of Saint Cainnech of Aghaboe was composed.Charles-Edwards, Early Christian Ireland, pp. 262–264; since the place-name Domnach represents a very early church, it is probably that Domnach Mór Roigni—modern Donaghmore, County Laois—was earlier than Aghaboe and that the rise of Aghaboe followed the expulsion of the Corcu Loigde rulers from Osraige and the coming to power of Cerball's ancestors. The name Osraige—the Deer people—is among the oldest group of Irish tribal names. Although genealogists in the Early Christian period explained such names by recourse to eponymous ancestors, the names are likely those of totemic animals or tribal deities.Mac Niocaill, Ireland before the Vikings, pp. 3–4; more ...
Osraige was only one túath among 150 in Ireland. The average túath was small, perhaps 500 square kilometres in area with a population of some three to four thousand. Osraige was atypical, much larger than this, covering perhaps 2000 square kilometres astride the River Barrow in the modern counties of Kilkenny, Laois, and Offaly. In principle, each tuath had its own king and court and bishop, but political power generally rested with the provincial over-kings.Byrne, Irish Kings, pp.46–47; Kelly, Early Irish Law, pp. 1–16; Charles-Edwards, Early Christian Ireland, pp. 102–106. The area given is that of the modern diocese of Ossory.
At the time of Cerball's birth Osraige lay within the province and kingdom of Munster, ruled by the Eóganachta from the royal centre of Cashel. Osraige lay at the extreme eastern edge of Munster bordering the neighbouring province of Leinster. For a period in the seventh century, most of southern Osraige was ruled by the Corcu Loígde, rulers of Munster before the coming of the Eóganachta. The Frithfolad Muman text states that the Osraige had once been kings of Munster and makes it clear that they were a privileged and powerful group, but no longer a major force, "the respectable has-beens of Munster politics".Charles-Edwards, Early Christian Ireland, p. 541.
The period of Cerball's life covered much of the first Viking Age, and he is notably mentioned in later Nordic sources. The Icelandic Landnámabók describes Cearbhall (Kjarvalur) as ruler of Dublin and Earl of Orkney and opens with a list of the most prominent rulers in Viking-age Europe, listing this Ossorian king alongside other well-known rulers of that era, specifically Popes Adrian II and John VIII; Byzantine Emperors Leo VI the Wise and his brother Alexander; Harald Fairhair, king of Norway; Eric Anundsson and his son Björn Eriksson rulers of Sweden; Gorm the Old, king of Denmark; and Alfred the Great, king of England. While several kingdoms in Britain – East Anglia, Fortriu, Mercia, and Northumbria – would collapse under the shock of Viking attacks, their impact in Ireland was very much less immediate. In the first half of the ninth century, raiders appear to have come in small groups, increasing in size until larger forces appear, such as that led by the shadowy Turgéis (Turgesius) in the 840s, and those led by Amlaíb and Ímar from the 850s onwards. Vikings would be both enemies and allies for Cerball and other Irish kings. In the long run, the creation of Norse–Gaelic towns by Vikings operating as traders rather than raiders would change the Irish political landscape, but the results of this were seen in the tenth and eleventh centuries rather than the ninth.Wanting.
Máel Sechnaill and the Danes Cerball succeeded his father Dúnlang (or Dúngal) mac Fergaile as king of Osraige in 842.Hudson, "Cerball"; Dúnlang's death is reported by the Annals of Ulster, s.a. 842. At this time the High King of Ireland was Máel Sechnaill mac Máele Ruanaid who was married to Cerball's sister Land. Cerball in turn was married to a daughter of Máel Sechnaill.Annals of Ulster, s.a. 842, 847; Fragmentary Annals, FA 246; Hudson, "Cerball"; Charles-Edwards, "Máel Sechnaill"; Downham, "Cearbhall", pp. 6–7.
The first report of Cerball is in 846, when Vikings attacked into northern Osraige, destroying a church at Coolcashin (near Galmoy), and plundering an unidentified settlement at Cúl Maine. Here the raiders were besieged for a fortnight by Cerball's army and lost heavily.Annals of the Four Masters, s.a. 844; Downham, "Cearbhall", pp. 9–10. These Vikings may have come from the region of modern County Carlow, then as now in southern Leinster. The following year Cerball defeated an attack by Vikings from the Irish midlands, perhaps from Dublin, led by one Hákon. This battle is said by some sources to have taken place at Carn Brammit, a site which can no longer be identified.Downham, "Cearbhall", p. 10; Downham, Viking Kings, p. 237; Annals of Ulster, s.a. 848; Annals of the Four Masters, s.a. 846; Chronicon Scotorum, s.a. 847.
The late Annals of the Four Masters record an invasion of Osraige in 848 by the Uí Ceinnselaig of southern Leinster, led by their king Echtigern mac Guaire. Cerball played a part in Echtgern's removal in 853. The Annals of Ulster report that Echtigern was killed "deceitfully" by Cerball and one Bruatur of Áed, and that Bruatur was killed by his own household a week later.Downham, "Cearbhall"; Annals of the Four Masters, s.a. 846; Annals of Ulster, s.a. 853.
In 854, the Fragmentary Annals say that Cerball was sent into Munster by his brother-in-law to collect tribute and hostages.Fragmentary Annals, FA 246.
In 855, he is said to have slaughtered a Viking force under a certain Rodolb. In the aftermath of the battle Cerball was captured by other Vikings, but succeeded in escaping. Shortly afterwards Cerball aided a force of Danes led by a chief named Horm in their war with the Norwegians. The Danes may well have settled at what is now Waterford. The Munstermen asked Cerball's help against the Norse, and Cerball with the men of Osraige, Horm's Danes and some of the men of Munster inflicted a heavy defeat on the Norse. His ally Horm was killed raiding in Wales by Rhodri the Great.Fragmentary Annals, FA 249, FA 251 & FA 254; Annals of Ulster, s.a. 856.
