Cú Chulainn Was Told the Boy Was His Son

The fight on the strand

On the strand at Tracht Eisi, the champion of Ulster is losing a wrestling match in the sea. His opponent is a boy who will not say his name. Cú Chulainn reaches for the Gáe Bulg, the barbed spear that Scáthach taught to him and to no one else, and the boy dies.

The popular version summarised on Wikipedia frames this as a tragedy of ignorance: a father who could not have known whom he was fighting. The oldest surviving version does not allow that excuse. In Aided Óenfhir Aífe, "The Tragic Death of Aífe's Only Son," the father is told who the boy is before the fight begins. He also wrote the rules that kept the boy silent.

Aífe and the price of mercy

The story starts in Scotland. Cú Chulainn has gone to Dún Scáith on the Isle of Skye to train under the warrior woman Scáthach, because Emer's father hopes the ordeal will kill him. While he is there, Scáthach goes to war against Aífe, her rival. Some versions make Aífe her twin sister. The Connla tale calls her simply Scáthach's sister. The family tree shifts between texts.

Cú Chulainn fights Aífe alone and finds her his equal. So he cheats. He shouts that her horses and chariot, the things she values most, have fallen off a cliff. When she turns, he seizes her and sets a sword at her throat. He spares her on two conditions: she ends her feud with Scáthach, and she bears him a son.

Three rules for an unborn son

Before he leaves for Ireland, Cú Chulainn gives Aífe a gold thumb-ring. When the boy is old enough to wear it, she is to send him to Ireland. Then Cú Chulainn puts three geasa, binding prohibitions, on the unborn child. The boy may not turn back once he has set out. He may not refuse a challenge. He may never tell anyone his name.

Each rule sounds like a champion's code. Put together, they guarantee that the boy will reach Ulster as a nameless stranger who cannot back down from a fight. In the Yellow Book of Lecan, these rules come from the father.

Ulster sends its men

Eight years later, by the reckoning in the Cú Chulainn tradition, the boy comes ashore at Tracht Eisi and practises his feats on the sand. The Ulaid watch and grow afraid. King Conchobar reasons that any land producing boys this skilled must hold warriors who would pound the Ulaid to dust.

They send Condere son of Echu to ask the boy his name and lineage. The boy refuses both. Condere praises him anyway and invites him to meet the Ulaid. The boy answers with an offer: Ulster can fight him one at a time or all together. Condere, he adds, is not worth fighting.

Conall Cernach goes next, the hero raised in the same house as Cú Chulainn on Muirthemne Plain. He boasts that the Ulaid will not be shamed while he lives. The boy sends a sling stone into the air so hard that the sound alone knocks Conall off his feet. Then he disarms him. Conall walks back shamed.

Emer names the boy

This is the scene the popular version summarised on Wikipedia leaves out. As Cú Chulainn moves toward the shore, his wife Emer tells him not to fight. The boy, she says, is his own son, Connla, and his mother is Aífe.

Cú Chulainn rebukes her. In Wikipedia's summary of the Yellow Book text, he says heroic deeds "are not performed with a woman's assistance." For the sake of the Ulaid, he would fight any intruder, whoever the intruder was. So he goes down to the water having heard the name. He asks the boy to identify himself and warns him he will die if he refuses. The boy, bound by his father's rule, refuses.

The spear and the calves

They wrestle in the water, and Connla gains the upper hand. Therefore Cú Chulainn uses the Gáe Bulg, the barbed spear thrown with the foot that has to be cut out of its victim. Connla is fatally wounded.

Cú Chulainn carries him to the shore and names him to the Ulaid as his son. Connla greets each hero of Ulster in turn, then bids his father farewell, then dies. A marker is raised over his grave. The text closes on cattle rather than speeches: "for three days not a calf of the cattle of the Ulaid was left alive after him."

What the popular version changed

The version summarised in Wikipedia's main Cú Chulainn article tells a gentler story about the father. There, Aífe binds the boy to silence and combat as revenge for being replaced by another woman. Connla learns mid-fight who his opponent is and misses his spear throw on purpose. His last words say they would have carried "the flag of Ulster to the gates of Rome and beyond."

None of that appears in the Yellow Book narrative. In the old text the father sets the bonds, the wife names the son, and the son does not spare anyone; he simply wins the wrestling until the spear comes. W. B. Yeats moved further still. His 1892 poem "Cuchulain's Fight with the Sea" makes Emer the mother, which removes Aífe from the story altogether.

Manuscripts, lawyers, and other fathers

The Yellow Book text is late Old Irish, dated to the ninth or tenth century. Scholarly references include Kuno Meyer's "The Death of Conla" in Ériu in 1904, and Jeffrey Gantz's Early Irish Myths and Sagas in 1981. A second version survives in the manuscript TCD 1336, and someone appended legal commentary to it about accountability and compensation. One way to read that commentary is as treating the killing like a case with a liable party. The story also appears in the place-lore of Lechtán Óenfhir Aífe, in Geoffrey Keating's History of Ireland, and in an Early Modern Irish version, Oidheadh Chonlaoich.

The pattern is shared across traditions. In the Shahnameh, Rostam kills his son Sohrab in a closely matched wrestling duel, with a jewel token between them. In the lost Greek Telegony, the pattern runs the other way: Telegonus, son of Circe, kills his father Odysseus with a spear tipped with a stingray's spine. The scholar Edward Petit argued that this spine may lie behind the Gáe Bulg, which some texts make from a sea monster's bone. That is one scholar's argument, not a consensus. The Germanic Hildebrandslied sets Hildebrand against his son Hadubrand, but its ending is lost. The Mahabharata pairs Arjuna with his son Babhruvahana.

The Irish text adds something that the summaries of the other stories do not mention: a wife who says the son's name aloud before the fight. In the oldest version, Cú Chulainn heard it and went down to the water anyway.
