Lugh is the shining young hero of the Irish gods. He is Lugh Lámfada, “of the long arm,” and Samildánach, “skilled in all the arts.” When he came to the court of the Tuatha Dé Danann at Tara, he was admitted because he alone possessed every skill at once: carpenter, smith, warrior, harper, poet, historian, sorcerer, physician. He led the gods to victory over the monstrous Fomorians and killed his own grandfather, Balor of the Evil Eye. He was the divine father of the hero Cú Chulainn. And he gave his name to Lughnasadh, the great harvest festival of early August, still celebrated in Ireland.
Lugh is also one of the few Irish gods whose worship can be traced across the Celtic world. His name appears in Gaul, Britain, and Spain, in the names of cities and in dedications to a god called Lugus. He may have been one of the most important gods of the ancient Celts.
Birth and Parentage
Lugh was born of a union between the two rival races of Irish myth. His father was Cian, son of the physician-god Dian Cécht, of the Tuatha Dé Danann. His mother was Ethniu (or Eithne), daughter of Balor, the king of the Fomorians.
A later folk tradition tells the story in detail. Balor had been warned by a prophecy that he would be killed by his own grandson. To prevent it, he locked his only daughter Ethniu in a crystal tower on Tory Island off the coast of Donegal, guarded by women, where she would never see a man. But Cian, whose magical cow Balor had stolen, entered the tower disguised as a woman with the help of a druidess, and Ethniu bore triplets. Balor had the babies wrapped in a cloth and thrown into the sea. Two drowned (or became seals), but one fell from the cloth into the bay and was rescued. That child was Lugh.
He was fostered by Manannán mac Lir, the sea god, or in other versions by Tailtiu, a queen of the Fir Bolg, or by the smith Goibniu. He grew up far from the court of the gods.
Master of All Arts
The most famous story of Lugh is his arrival at Tara, told in the Second Battle of Mag Tuired. The doorkeeper would admit no one without a skill. Lugh named each of his skills in turn — and each time the doorkeeper said the Tuatha Dé already had such a person. Finally Lugh asked whether anyone at Tara had all of these skills together. No one did, and he was admitted. (See The Second Battle of Mag Tuired.)
Inside, he proved his gifts. He won at fidchell, a board game like chess. He lifted a flagstone that it took eighty oxen to move and threw it out of the hall. He played the harp’s three great strains — the sorrow strain, the joy strain, and the sleep strain — so that the company wept, laughed, and slept.
King Nuada was so impressed that he stepped aside and let Lugh lead the Tuatha Dé in their war against the Fomorians.
The Death of Balor
At the Second Battle of Mag Tuired, Lugh faced his grandfather Balor, whose single eye destroyed whatever it looked upon. As the eye was opened, Lugh cast a stone from his sling that drove the eye through the back of Balor’s skull, so that its deadly gaze fell upon the Fomorian army. The prophecy was fulfilled, and the Fomorians were defeated.
The Sons of Tuireann
Another major story, Oidheadh Chloinne Tuireann (“The Tragic Death of the Children of Tuireann”), shows a harsher side of Lugh. His father Cian was murdered by three brothers, the sons of Tuireann, who stoned him to death because of an old feud. The earth refused to hide the body, rejecting it six times, and the stones themselves told Lugh who had done the deed.
As compensation, Lugh demanded an extraordinary éiric (blood-price): a series of magical objects from across the world — the apples of the Garden of the Hesperides, the pigskin of the king of Greece that healed all wounds, the poisoned spear of the king of Persia, the horses and chariot of the king of Sicily, the seven pigs of King Asal that could be eaten and returned to life, the hound whelp of the king of Ioruaidh, the cooking spit of the women of Fianchuibhe — and finally, to give three shouts on the hill of Miodhchaoin, whose guardians had sworn that no one should ever shout there.
The brothers achieved every task, but were mortally wounded at the last. When their father Tuireann begged Lugh to lend them the healing pigskin, Lugh refused. The sons died. The tale is one of the “Three Sorrows of Storytelling,” along with the Children of Lir and the story of Deirdre.
Lugh and Cú Chulainn
In the Ulster Cycle, Lugh is the divine father of Cú Chulainn. His mother Deichtine, sister of King Conchobar, swallowed a small creature in a drink, and Lugh appeared to her in a dream to tell her she was carrying his child.
During the Táin Bó Cúailnge, when Cú Chulainn is exhausted and wounded from weeks of fighting, Lugh appears to him as a tall, handsome warrior in a green cloak. He tells Cú Chulainn to sleep for three days and three nights while he fights in his place and heals his wounds with herbs (see The Cattle Raid of Cooley).
The Spear of Lugh
Among the four treasures of the Tuatha Dé was the Spear of Lugh, brought from the city of Gorias. No battle could be sustained against it. In later tradition the spear became fiery and bloodthirsty: it had to be kept with its head in a cauldron of sleeping-draught, or it would burst into flame and kill. Some scholars have connected it with the bleeding lance of the Grail legends (see The Holy Grail).
Lugh Across the Celtic World
Lugh’s name appears in many places across Europe:
- Lugdunum (“fort of Lugus”) was the Roman name of Lyon in France, the capital of Roman Gaul. The Roman emperor Augustus chose August 1st, perhaps the festival of Lugus, for a great assembly of the Gauls there. The same name gave rise to Leiden in the Netherlands and Laon in France.
- Luguvalium, Roman Carlisle in England, may be named after him.
- Inscriptions to the Lugoves (plural) have been found in Spain and Switzerland, some dedicated by shoemakers.
- Julius Caesar, describing the gods of Gaul, said that their chief god was the one he called Mercury, “the inventor of all the arts.” Many scholars believe this was Lugus.
- In Wales, Lleu Llaw Gyffes (“the bright one of the skilful hand”), a hero of the Mabinogi, is a cognate figure.
Lughnasadh
Lugh is honoured in the festival of Lughnasadh (Lúnasa in modern Irish, the name of the month of August), one of the four great seasonal festivals of the Celtic year, held at the beginning of the harvest. It was said to have been founded by Lugh himself as a funeral feast for his foster-mother Tailtiu, who died of exhaustion after clearing the plains of Ireland for agriculture. See Lughnasadh: The Harvest Festival of Lugh.
Symbolism
Lugh represents the ideal of the complete individual — the one who masters every skill, combining warrior prowess with artistic, intellectual, and magical gifts. He is a god of light, youth, and victory, and a bridge between the old and new orders. Born of both the Tuatha Dé and the Fomorians, he reconciles opposites and, in killing Balor, frees the land from oppression.
His story has been compared with that of the Greek Perseus, another hero whose grandfather tried to prevent a prophecy of death by locking up his daughter, and with other young gods who overthrow an older, monstrous generation.
