Irish God of the Earth, Magic, and Abundance
The Dagda is the supreme elder of the Tuatha Dé Danann. He has many names. Dagda itself means “the Good God” — not good as in kind or gentle, but good as in supremely excellent at everything. A second name is Eochaid Ollathair — “the Great Father.” No matter who the official king was, the Dagda was the main guide and elder of the Tuatha Dé Danann during their greatest years. Another interesting name for him is Ruad Rofhessa (Lord of Great Knowledge), indicating the Dagda’s role as chief druid of the Tuatha
His three possessions tell you a lot about him.
His cauldron, the Undry, was one of the Four Treasures of the Tuatha Dé Danann, brought from the mythological city of Murias. It was completely inexhaustible — no matter how many people came to it, no one ever left hungry.
His harp, Uaithne, played three strains of music: sorrow, laughter, and sleep. When he played, the seasons changed. When the Fomorians stole the harp during the Battle of Mag Tuired and hung it on a wall, the Dagda went to take it back. He called it from the wall — and it flew to him, killing nine Fomorians on the way.
The Dagda doesn’t look like what you’d expect. He is enormous and rough, wearing a short tunic that barely covers him, dragging his great club on a wheel. He looks like a massive ungainly farmer. That’s the point. His power is not in his appearance.
Before the Second Battle of Mag Tuired, the Dagda meets the Morrígan at a river crossing, where they agree that she will support the Tuatha Dé Danann. After the battle, she declares their victory and foretells what will happen next, showing her role in war and fate.
The Fomorians tried to humiliate him by making him eat a pit-sized cauldron of porridge — oatmeal, fat, and whole animals. He ate it all, scraped the pot with his finger and then lay down (probably pretending) to sleep. The attempted mockery became a demonstration of exactly how much he could hold.
After the Milesians defeated them, he divided the síde — the Otherworld mounds beneath Ireland’s hills — among his people, keeping Brú na Bóinne (now known as Newgrange) for himself. Aengus eventually took Brú na Bóinne from him. Aengus asked to stay at there “for a day and a night.” In Irish that phrase covers all possible time — every moment is either a day or a night. When the Dagda tried to reclaim it, Aengus pointed out he’d been given it forever. The Dagda couldn’t find a way around it. Aengus kept the Brú.
He is also the father of Brigid, goddess of poetry, healing, and smithcraft; Bodb Derg, king of the Otherworld; Cermait; and Aed Lámderg.
