The myths of Macha
3 myths, each traced to its primary text and corpus sources.
The Death of Nemed’s Macha
The sailors saw a tower of gold on the shore and turned their ships towards it. They hoped to seize its wealth, but the sea resisted them. Every vessel was dashed to pieces except the ship carrying Nemed and his wife, Macha. They survived the wreck and continued towards Ireland.
Nemed, also called Neimheadh, had left Scythia with an armada. The Book of Invasions places him in Ireland’s mythological history as an early settler of the island. He was said to descend from Noah through Japheth and from Magog, the monster god of Britain. His voyage began after the people of Partholón had been destroyed by an unknown plague. Nemed arrived three decades after their disappearance, while the Fomorians still raged through the land.
The journey lasted eighteen months. Nemed and Macha eventually reached Ireland, where the Nemedians settled. Macha died soon after their arrival. Nemed named a height Ard Macha in her memory. The name means “the heights of Macha” and gave its name to Armagh in present-day Northern Ireland.
This Macha is Nemed’s wife. She is distinct from the other figures called Macha in Irish tradition. One Macha lived with the farmer Crunniuc and was forced to race while pregnant, dying after giving birth to twins. Another, Macha Mong Rua, or Red-Haired Macha, was a warrior who took power after her father’s death. Macha is also counted among the three Morrigna, the war goddesses. These figures are connected with Emain Macha, Ulster, and different strands of Irish myth.

Macha’s Race and the Ulster Curse
Heavily pregnant, Macha was summoned by a messenger to race the king’s horses. She pleaded that she might give birth at any moment. The messenger replied that her husband would die if she refused, so she went to the race. Her labour pains had already begun when she arrived.
Macha begged King Conchobar not to make her run. He refused. She appealed to the people gathered there. She reminded them that every one of them had been born from a mother and asked them to wait until her children were born. The crowd remained silent. Macha warned that their treatment of her would bring great evil upon Ulster.
The king asked her name. She answered that she was Macha, daughter of Sainrith mac Imbaith, the wondrous son of the ocean. She declared that her name would be given to the place. The race began. Macha ran around the field with the speed of a horse and passed the king’s chariot. She crossed the finish line just ahead of the team. At the end of the course, she gave birth beside the chariot to twins, a son and a daughter.
Macha then cried out that the men of Ulster who had heard her scream would suffer the same pains in their times of greatest difficulty. The pangs would seize them whenever Ulster was invaded. They would last for five days and four nights, leaving those afflicted with no more strength than a woman in labour. The curse was said to remain for nine generations. The place was thereafter called Emain Macha, the Twins of Macha.

Macha Mong Ruad Claims the Kingship
Áed Ruad drowned in a waterfall. Macha Mong Ruad, his daughter, then attempted to take his place in the succession. Dithorba and Cimbáeth, her father’s colleagues and co-rulers, opposed her claim. Macha waged war against them. She killed Dithorba and defeated Cimbáeth, then joined herself to him through marriage.
Dithorba’s five sons escaped after their defeat. Macha pursued them and disguised herself as an ancient hag. The sons attempted to rape her, but she overcame all five. She brought them back to Emain Macha, where her warriors tried to execute them.
Macha chose another punishment. She forced Dithorba’s sons to dig the great earthworks later known as Navan Fort. The site contains a large artificial mound, several sacred wells, a racecourse, and other ritual places. Macha’s connection with Ulster and Emain Macha links her story with traditions of the Ulster Cycle. In this account, she fights to succeed her father as ruler of Ireland. Her victory over Dithorba and Cimbáeth gives her control of the succession, while her treatment of Dithorba’s sons establishes the earthworks associated with her name. The account presents her as a warrior woman who takes the throne after defeating those who opposed her claim.
