Story Summary
Experience the tragic duel of Cú Chulainn and Ferdiad, two brothers-in-arms forced to fight to the death in the epic Celtic myth, the Cattle Raid of Cooley.
During the great Cattle Raid of Cooley, Queen Medb of Connacht found her entire army halted by a single champion: Cú Chulainn. Frustrated, she turned to the only man who could match him, Ferdiad, Cú Chulainn’s own foster-brother and dearest friend. Through bribery and threats of shame, Medb coerced Ferdiad into a duel at the ford. For three days, the heroes fought with unparalleled skill. Each evening, they ceased their combat to exchange food, medicine, and memories of their training under the warrior-woman Scáthach, weeping for the tragedy of their situation. On the fourth day, the duel turned desperate. As they grappled in the river, Cú Chulainn’s battle-frenzy took hold. He called for the Gáe Bulg, his legendary notched spear. It was a weapon of certain death, and with one throw, it pierced Ferdiad’s armor. As Ferdiad fell, the victory tasted like ash; Cú Chulainn took his brother in his arms and lamented, realizing that in winning the battle for Ulster, he had lost his heart's companion.
The Moral
The highest tragedy occurs when duty and honor force us to destroy the ones we love most.
“All play is a fight, all sport is a grief, until Ferdiad comes to the ford.”
Fun Fact
In Irish tradition, the 'horn-skin' of Ferdiad was so thick that no normal weapon could pierce it, which is why Cú Chulainn was forced to use the supernatural Gáe Bulg.
