Cú Chulainn

Lore & Background

Cú Chulainn's childhood began with miraculous origins. In one version, his mother Deichtine assisted a host who was actually the god Lug; after the child she raised died, Lug placed his son in her womb. In another, Deichtine herself gave birth to Sétanta under Lug's roof. Raised alongside Conall Cernach by Amergin and Findchóem on Muirthemne Plain, he joined the boy-troop at Emain Macha and immediately demonstrated his power by defeating them single-handedly after a misunderstanding regarding protection customs. At age seven, overhearing a prophecy that taking arms that day would bring everlasting fame but a short life, he demanded weapons from Conchobar, eventually receiving the king's own set when others shattered. He also requested a chariot, only for the king's to survive his strength. His training took him to Alba (Scotland) under the warrior-woman Scáthach at Dún Scáith. There, he mastered all arts of war and received the Gáe Bulg, a terrible barbed spear thrown with the foot that must be cut from its victim. He formed a close bond with fellow trainee Ferdiad, sharing bed and words of love, though this relationship remains controversial.

In Their Own Story

The narrative of Cú Chulainn is punctuated by moments of extreme violence and supernatural intensity. As a child, he killed Culann's hound either by smashing it against a standing stone or driving a sliotar down its throat with his hurley, leading the druid Cathbad to name him Cú Chulainn. Later, after taking up arms at age seven, he went on a foray and slew the three sons of Nechtan Scéne who had boasted they killed more Ulstermen than remained alive. Returning in his ríastrad, he terrified the people until women bared their breasts to distract him; even then, he required three barrels of water—first exploding from heat, second boiling, and third warming—to cool his body. During the Táin Bó Cúailnge, he faced Queen Medb's armies alone. His wife Emer was his primary partner, though he had other lovers, including Aífe, with whom he fathered a son named Connla, whom he tragically killed without recognizing him as his own.

Reader's Guide

To understand Cú Chulainn, one must look to the Ulster Cycle of Irish mythology. His name translates to 'Culann's Hound,' though 'cú' also serves as a figurative term for warrior, potentially meaning 'Culann's Warrior.' Folklorist Dáithí Ó hÓgáin suggested it might derive from an old word for chariot, implying 'chariot-warrior.' His birth name Sétanta may link to the Setantii tribe of Celtic Britain. In modern culture, his image is immortalized in Oliver Sheppard's bronze sculpture of the dying hero at the Dublin General Post Office (GPO), commemorating the Easter Rising of 1916, and a stained glass panel at St. Enda's School. Lady Gregory retold these legends in her 1902 book 'Cuchulain of Muirthemne,' though she paraphrased originals and omitted much violent content.
