Heroes of the Ulster Cycle
The Ulster Cycle is the oldest and most complex of the four cycles of Irish mythology. Its central text — the Táin Bó Cúailnge, the Cattle Raid of Cooley — is the longest narrative in early Irish literature and one of the great epic texts of medieval Europe. The cycle is set in the Iron Age, in a world of chariot warriors and heroic single combat, centred on the court of King Conchobar mac Nessa at Emain Macha in Ulster.
At its heart is Cú Chulainn — the greatest hero in Irish tradition — and his lone defence of Ulster against the armies of Connacht while the other Ulster warriors were paralysed by Macha’s curse. But the cycle is far larger than Cú Chulainn. It contains the tragedy of Deirdre and the sons of Uisneach, the scheming of Medb and Ailill, the complex loyalty of Fergus mac Róich, and dozens of figures whose stories intersect across a generation of war.
The figures here represent the major players of the Ulster Cycle — kings, warriors, druids, and the women whose choices shaped everything that followed.
Ulster Cycle Heroes
Ailill mac Máta
King of Connacht Ailill mac Máta was the king of Connacht and the husband of Medb — the man whose possession of the white-horned bull Finnbennach, the one item in which he exceeded his wife, was the direct cause of the Táin Bó Cúailnge. Finnbennach had originally been born in Medb’s herd. It transferred itself […]
Ainnle
Son of Uisneach Ainnle mac Uisneach was the second of the three sons of Uisneach — the middle brother who went into exile in Scotland when Naoíse took Deirdre from Conchobar mac Nessa‘s court, and who was killed with his brothers when they came back. The sons of Uisneach acted as one. They went together, […]
Ardan
Son of Uisneach Ardan mac Uisneach was the youngest of the three sons of Uisneach — the third brother who went into exile in Scotland when Naoíse took Deirdre from Conchobar mac Nessa‘s court, and who was killed with his brothers on their return. He lived in Scotland with his brothers in honourable service to […]
Cathbad
Chief Druid of Ulster Cathbad was the chief druid of Conchobar mac Nessa‘s Ulster. His authority was equal to the king’s in anything involving the supernatural. He made two prophecies that shaped everything in the Ulster Cycle. The first was about Deirdre. At a feast, an unborn child cried out from inside her mother’s womb. […]
Celtchar mac Uthechair
The Dark Champion Celtchar mac Uthechair was one of the great champions of Conchobar mac Nessa’s Ulster — a warrior of the first rank whose career was shaped by blood-debt, penance, and a death that came from his own weapon. He killed the husband of a woman who had shamed him. The killing required three […]
Conall Cernach
The Victorious Conall Cernach was the second champion of Ulster — ranked directly behind Cú Chulainn in the Ulster warrior hierarchy — and the man who avenged Cú Chulainn’s death before sundown on the day it happened. He had sworn an oath: if Cú Chulainn were killed before him, he would avenge it before the […]
Conchobar mac Nessa
King of Ulster Conchobar mac Nessa was the king of Ulster, lord of Emain Macha, and the ruler whose court was the setting for the entire Ulster Cycle. He was not the greatest warrior of the court — that was Cú Chulainn. He was the king whose decisions caused the catastrophes, and who lived to […]
Cú Chulainn
The Hound of Ulster Cú Chulainn is the greatest hero of the Ulster Cycle and the most celebrated warrior in all of Irish myth. He was the son of Lugh — the god who mastered every art — and the mortal woman Deichtine, sister of Conchobar mac Nessa. He grew up at Emain Macha as […]
Cú Roí mac Dáire
The Wizard King of Munster Cú Roí mac Dáire was the king of Munster and one of the most powerful supernatural figures in the Ulster Cycle — a warrior and sorcerer who stood outside the Ulster-Connacht conflict that dominated everything else, and whose castle rotated nightly so that no enemy could find its door. His […]
Deirdre
Deirdre of the Sorrows The druid Cathbad prophesied from inside Deirdre’s mother’s womb — before she was even born, from the sound of her first cry — that she would be the most beautiful woman in Ireland, that kings and lords would go to war over her, and that great ruin would come to Ulster […]
Fer Diad
Champion of the Ford Fer Diad mac Damáin was the foster-brother-in-arms of Cú Chulainn — they had trained together under Scáthach on the Isle of Skye, learning the same techniques, facing the same trials, becoming in the tradition’s assessment the one warrior who could genuinely match Cú Chulainn as an equal. His skin had hardened […]
Fergus mac Róich
The Exiled King Fergus mac Róich was the king of Ulster before Conchobar mac Nessa. He gave up the throne, became the greatest warrior at the court of the king who replaced him, and was eventually driven out when that king broke his word. He gave up the kingship himself. Conchobar’s mother Nessa negotiated with […]
Láeg mac Riangabra
Charioteer of Cú Chulainn Láeg mac Riangabra was the charioteer of Cú Chulainn — the man who drove the Grey of Macha and the Black of Saingliu through every battle of the Táin Bó Cúailnge, who stood at the ford while Cú Chulainn fought, who handed weapons across at need, who managed two supernatural horses […]
Lóegaire Buadach
The Triumphant Laoghaire Buadhach — “Laoghaire the Triumphant” — was the third champion of Ulster, ranked behind Cú Chulainn and Conall Cernach in the explicit Ulster warrior hierarchy. He was a genuine warrior of the first rank — present throughout the Ulster Cycle’s set-piece warrior-ranking episodes, consistently significant, never first. His clearest moment is the […]
Medb
Queen of Connacht Medb was the queen of Connacht, and the greatest war in the Ulster Cycle began because her husband had a bull she didn’t. She and Ailill mac Máta were lying in bed comparing their possessions — cataloguing their wealth item by item — and found themselves exactly equal in everything except one […]
Naoise
Lover of Deirdre Naoíse mac Uisneach was the eldest of the sons of Uisneach and the man Deirdre chose over the king who had raised her. She described him to his face in three colours: his hair the black of a raven, his body the white of snow, his cheeks the red of blood. She […]
Scáthach
The Shadow, Warrior-Teacher of Skye Scáthach — “the Shadowy One” — was the warrior-woman of the Isle of Skye who trained Cú Chulainn in the arts of war, gave him the gae bolga, and made him the greatest fighter in Ireland. Without Scáthach, Cú Chulainn has no gae bolga. Without the gae bolga, Fer Diad […]
