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 Sétanta, and he took the name Cú Chulainn — Hound of Culann — after killing the smith Culann’s guard dog and offering to stand in its place until a replacement could be trained.
He was given a choice of fates early. A long, unremarkable life, or a short life of surpassing glory and permanent fame. He chose the short life. Everything that follows is what that choice contained.
His most specific supernatural power was the ríastrad — the warp-spasm. In battle his body distorted grotesquely: one eye sucked back into his skull, the other bulging on his cheek, his muscles rearranging, heat rising from his body in visible waves. It made him something other than an ordinary fighter — a different order of being entirely, something that couldn’t be faced by the same means as a man.
He trained under Scáthach on the Isle of Skye, crossing the Bridge of the Leaps to reach her school at Dún Scáith. She gave him the gae bolga — a barbed spear thrown with the foot, delivered underwater, that opened into multiple barbs on entry. No other warrior had one. He used it to kill his closest friend Fer Diad at the ford during the Táin Bó Cúailnge, fighting him for three days before the gae bolga ended it. He mourned over the body. He used it again to kill his own son Connla — not recognising him until the spear had already struck.
The Táin Bó Cúailnge is his defining episode. Medb of Connacht raised her army and marched into Ulster while all of Ulster’s warriors lay under Macha‘s curse — paralysed, unable to fight. Cú Chulainn was exempt, being the son of a god. He held Ulster alone, fighting single combats at the ford against Connacht’s champions, day after day, while the province he was protecting could do nothing to help him.
His divine father Lugh appeared to him during the Táin to tend his wounds while he slept for three days — the god caring for the hero who had inherited his nature and was spending it in the service of a curse he hadn’t caused.
He died bound to a pillar stone. He tied himself upright so he would die on his feet. His enemies waited. When a raven landed on his shoulder, they knew he was gone. The Morrígan — who had offered him her love and been refused, who had attacked him in three animal forms during his combats, who had healed herself from his blows when he unknowingly blessed her — settled on him as a crow at the end. That was the last act of their long, complicated relationship.
His wife was Emer, daughter of Forgall Monach, won through trials her father designed to kill him. His divine lover was Fand, wife of Manannán mac Lir, who drew him into the Otherworld and loved him there until Manannán shook his cloak between them. His charioteer was Láeg. His horses were the Grey of Macha and the Black of Saingliu — both wept blood before he died.
