Cú Chulainn: The Hound of Ulster, Greatest Hero of Irish Mythology

Every heroic literature has its supreme figure, and Ireland's is a boy who never saw his eighteenth year old age. Cú Chulainn, the Hound of Ulster—centerpiece of the Ulster Cycle and of its great epic, the Táin Bó Cúailnge, the Cattle Raid of Cooley—is the perfected form of the Indo-European champion: superhumanly gifted, catastrophically radiant, and priced from birth. Son of the god Lugh the many-skilled by a mortal mother, nephew of King Conchobar, he was small, dark, and beautiful—the texts insist on the beauty with un-warlike tenderness—and he carried within him a thing the tradition regarded with equal parts reverence and horror: the ríastrad, the warp-spasm, the battle-frenzy that unmade his lovely form into a monster when combat took him. His legend is built of vows, single combats at fords, a divine father, an offended goddess, and a death met standing up, lashed to a pillar-stone so that he might die on his feet—and running through all of it, like the one string of a terrible harp, the theme Ireland assigned him to carry: the economics of glory, stated by the boy himself in the most famous sentence of Irish heroic literature. Overhearing the druid Cathbad say that whoever took arms on that day would be famous forever but short-lived, the boy demanded his weapons at once, and answered all remonstrance with: I care not though I were but one day and one night in the world, provided that my fame and my deeds live after me. Everything else in the cycle is the working-out of that contract.

The Hound's Name and the Warp-Spasm

He was born Sétanta, and won his true name at seven, in the episode that contains his whole character. Arriving late to a feast at the fort of Culann the smith, he found the smith's monstrous watch-hound loosed against him—and killed it bare-handed, driving his playing-ball down its throat. The company rejoiced; the smith grieved: who now would guard his herds and hall? And the child gave judgment against himself: he would rear the hound's replacement, and until it was grown, he himself would be Culann's hound—patrolling the smith's lands, guarding his goods. The druid Cathbad pronounced the sentence a naming: Cú Chulainn—the Hound of Culann—he would be called forever. Note what Ireland put into its supreme hero's name: not victory, not lineage—restitution. The greatest of the Gael is named for the debt he assumed at seven, for taking upon himself, as a person, the office his strength had destroyed. He was bound by it ever after in the strictest Irish form, the geis, the sacred prohibition: the Hound must never eat the flesh of a dog. Hold that clause; the death is already loaded in it.

The ríastrad deserves its notoriety. When the frenzy took him, say the texts in a passage of ecstatic monstrosity, he revolved within his own skin; his hair stood in spikes tipped with sparks of fire; one eye swallowed itself into his skull while the other bulged huge upon his cheek; his mouth widened to meet his ears; the hero-light rose in a column from his crown; and in that state he knew neither friend nor foe—returning from his first boyhood foray, he had to be plunged into three vats of cold water (the first burst, the second boiled, the third warmed) before Ulster dared let him indoors, and the women of Emain Macha were sent out bare-breasted to shame the boy's eyes down while the vats were readied. The tradition is explicit and the esoteric reader should receive it exactly: the supreme gift and the supreme deformity are one energy. The warp-spasm is the divine father's fire arriving without negotiation—power in a quantity the human vessel cannot hold and remain human—and Ulster's protocol (the shame, the vats, the graded cooling) is the oldest extant manual for the management of possession: the berserk state, the artist's fury, every seizure of more-than-personal force, must be met at the gates with humbling and cooled by degrees, or it will not distinguish friend from foe, for at full heat it has no friends.

The Ford, the Foster-Brother, and the Táin

His great ordeal is the Táin: Queen Medb of Connacht invades Ulster to seize the Brown Bull of Cooley at the precise season when the Ulstermen lie prostrate under an old curse—and the seventeen-year-old Hound, alone exempt, holds the province single-handed, invoking the right of single combat to meet Medb's champions one per day at the ford. The ford-fights of the Táin are the tradition's high altar of threshold-lore—the hero as the boundary itself, the province's whole sovereignty narrowed to one boy standing in running water—and their summit is the three-day duel with Ferdiad: his own foster-brother, his equal and beloved, trained with him by the warrior-woman Scáthach in Alba, sent against him by Medb's bribes and taunts. Each evening of the first two days the two embrace, share food and healing herbs across the ford, send each other physicians; on the third day Cú Chulainn kills him—with the gáe bolga, the terrible barbed spear of his secret training, delivered through the water—and then breaks over the body into the greatest lament in the epic: All play, all sport, until Ferdiad came to the ford. Ireland placed at the center of its national epic not a triumph but this: the recognition that the deepest duty of the boundary may one day require of its keeper the person most like himself, and that glory's full price is paid not in one's own blood but in one's brother's, and mourned forever.

His women complete the portrait: Emer of the six gifts, won by riddling courtship; Scáthach the trainer and Aífe her rival, on whom he begot the son, Connla, whom—by the machinery of geis and honor that the cycle winds tighter than any tragedy of the Greeks—he would one day kill unknowing at the shore, the boy under his own vow not to name himself. And against the women stands the goddess: the Morrígan, sovereign crow of battle, who offered the Hound her love at the ford and was refused—and who repaid the refusal by opposing him as eel, wolf, and heifer in mid-combat, and, at the end, by settling on his shoulder—the sovereign carrion-queen of the battlefield performing in person the office her diminished daughters would keep for the old families ever after, as the wailing herald of the great houses.

The Death Standing and the Esoteric Sum

For the end came as the geasa closed like a weir. His enemies, arrayed by the children of men he had slain, met him on the road with the one hospitality he could neither accept nor refuse: an old woman roasting dog-flesh, and the twin obligations—never refuse hospitality; never eat hound—ground against each other and broke him. He ate; his old debt-name turned in him; half his strength left through the violated geis. Speared mortally by Lugaid, he bound himself upright to the pillar-stone at Knockbridge with his own belt, that he might die standing, facing his enemies, sword in hand—and for three days, says the tradition, no man dared approach him, until the crow settled on his shoulder: the Morrígan, in her raven form, alighting to certify what no warrior would test. Then Lugaid took his head; and the hero-light, the texts say, went out of the sky of Ulster. The dying-standing image—cast in bronze by Oliver Sheppard, it stands today in the General Post Office in Dublin, the shrine of another rising—became the emblem of the nation's own theory of noble defeat.

Even his weapons kept the doctrine. The gáe bolga, the belly-spear of his secret training, entered as one barb and opened into thirty within the wound—it could not be withdrawn, only cut out—and Scáthach taught it to him alone: the unanswerable stroke reserved for the boundary's last necessity, and used, in the whole tradition, chiefly on the two he loved best, foster-brother and son. The tradition placed the unbeatable weapon and the unbearable griefs in the same hand deliberately; that is its entire theory of ultimate force.

The esoteric sum of the Hound is the contract read whole. He is the soul's champion-function in its purest recorded form: the faculty fathered by radiance—Lugh of every art, master of the shining ones—named for a debt, bound by vows that are also vulnerabilities, stationed alone at the ford of the sleeping province—and priced, from the day it chooses, at brevity for brightness. Every clause instructs: the gift arrives as deformity and must be cooled in stages; the vows that focus power are the exact channels by which power is finally drained—whoever would bind a champion, in any age, studies his geasa, not his sword-arm; the boundary-keeper's costliest combat is always against the foster-brother, the too-similar other; and the end, when the vows converge, is not escape but posture: the belt, the stone, the standing death, the fame that was the agreed fee collected in full. He got, to the letter, what the boy demanded of the druid: one blazing interval, and the deeds alive after him—alive enough that a modern republic put his dying body in its holiest public room. The contract, the tradition wants every reader to notice, was honored on both sides. It always is. That is the warning, and the glory.
