Various stories were told of the first peopling of Ireland. Banba, with two other daughters of Cain, arrived with fifty women and three men, only to die of the plague. Three fishermen next discovered Ireland, and "of the island of Banba of Fair Women with hardihood they took possession." Having gone to fetch their wives, they perished in the deluge at Tuath Inba.103 A more popular account was that of the coming of Cessair, Noah's granddaughter, with her father, husband, a third man, Ladru, "the first dead man of Erin," and fifty damsels. Her coming was the result of the advice of a laimh-dhia, or "hand-god," but their ship was wrecked, and all save her husband, Finntain, who survived for centuries, perished in the flood.104 Cessair's ship was less serviceable than her grandparent's! Followed the race of Partholan, "no wiser one than the other," who increased on the land until plague swept them away, with the exception of Tuan mac Caraill, who after many transformations, told the story of Ireland to S. Finnen centuries after.105 The survival of Finntain and Tuan, doubles of each other, was an invention of the chroniclers, to explain the survival of the history of colonists who had all perished. Keating, on the other hand, rejecting the sole survivor theory as contradictory to Scripture, suggests that "aerial demons," followers of the invaders, revealed all to the chroniclers, unless indeed they found it engraved with "an iron pen and lead in the rocks."106
Two hundred years before Partholan's coming, the Fomorians had arrived,107 and they and their chief Cichol Gricenchos fought Partholan at Mag Itha, where they were defeated. Cichol was footless, and some of his host had but one arm and one leg.108 They were demons, according to the chroniclers, and descendants of the luckless Ham. Nennius makes Partholan and his men the first Scots who came from Spain to Ireland. The next arrivals were the people of Nemed who returned to Spain, whence they came (Nennius), or died to a man (Tuan). They also were descendants of the inevitable Noah, and their sojourn in Ireland was much disturbed by the Fomorians who had recovered from their defeat, and finally overpowered the Nemedians after the death of Nemed.109 From Tory Island the Fomorians ruled Ireland, and forced the Nemedians to pay them annually on the eve of Samhain (Nov. 1st) two-thirds of their corn and milk and of the children born during the year. If the Fomorians are gods of darkness, or, preferably, aboriginal deities, the tribute must be explained as a dim memory of sacrifice offered at the beginning of winter when the powers of darkness and blight are in the ascendant. The Fomorians had a tower of glass in Tory Island. This was one day seen by the Milesians, to whom appeared on its battlements what seemed to be men. A year after they attacked the tower and were overwhelmed in the sea.110 From the survivors of a previously wrecked vessel of their fleet are descended the Irish. Another version makes the Nemedians the assailants. Thirty of them survived their defeat, some of them going to Scotland or Man (the Britons), some to Greece (to return as the Firbolgs), some to the north, where they learned magic and returned as the Tuatha Dé Danann.111 The Firbolgs, "men of bags," resenting their ignominious treatment by the Greeks, escaped to Ireland. They included the Firbolgs proper, the Fir-Domnann, and the Galioin.112 The Fomorians are called their gods, and this, with the contemptuous epithets bestowed on them, may point to the fact that the Firbolgs were the pre-Celtic folk of Ireland and the Fomorians their divinities, hostile to the gods of the Celts or regarded as dark deities. The Firbolgs are vassals of Ailill and Medb, and with the Fir Domnann and Galioin are hostile to Cúchulainn and his men,113 just as Fomorians were to the Tuatha Dé Danann. The strifes of races and of their gods are inextricably confused.
The Tuatha Dé Danann arrived from heaven—an idea in keeping with their character as beneficent gods, but later legend told how they came from the north. They reached Ireland on Beltane, shrouded in a magic mist, and finally, after one or, in other accounts, two battles, defeated the Firbolgs and Fomorians at Magtured. The older story of one battle may be regarded as a euhemerised account of the seeming conflict of nature powers.114 The first battle is described in a fifteenth to sixteenth century MS.,115 and is referred to in a fifteenth century account of the second battle, full of archaic reminiscences, and composed from various earlier documents.116 The Firbolgs, defeated in the first battle, join the Fomorians, after great losses. Meanwhile Nuada, leader of the Tuatha Dé Danann, lost his hand, and as no king with a blemish could sit on the throne, the crown was given to Bres, son of the Fomorian Elatha and his sister Eri, a woman of the Tuatha Dé Danann. One day Eri espied a silver boat speeding to her across the sea. From it stepped forth a magnificent hero, and without delay the pair, like the lovers in Theocritus, "rejoiced in their wedlock." The hero, Elatha, foretold the birth of Eri's son, so beautiful that he would be a standard by which to try all beautiful things. He gave her his ring, but she was to part with it only to one whose finger it should fit. This was her child Bres, and by this token he was later, as an exile, recognised by his father, and obtained his help against the Tuatha Dé Danann. Like other wonderful children, Bres grew twice as quickly as any other child until he was seven.117 Though Elatha and Eri are brother and sister, she is among the Tuatha Dé Danann.118 There is the usual inconsistency of myth here and in other accounts of Fomorian and Tuatha Dé Danann unions. The latter had just landed, but already had united in marriage with the Fomorians. This inconsistency escaped the chroniclers, but it points to the fact that both were divine not human, and that, though in conflict, they united in marriage as members of hostile tribes often do.
The second battle took place twenty-seven years after the first, on Samhain. It was fought like the first on the plain of Mag-tured, though later accounts made one battle take place at Mag-tured in Mayo, the other at Mag-tured in Sligo.119 Inconsistently, the conquering Tuatha Dé Danann in the interval, while Bres is their king, must pay tribute imposed by the Fomorians. Obviously in older accounts this tribute must have been imposed before the first battle and have been its cause. But why should gods, like the Tuatha Dé Danann, ever have been in subjection? This remains to be seen, but the answer probably lies in parallel myths of the subjection or death of divinities like Ishtar, Adonis, Persephone, and Osiris. Bres having exacted a tribute of the milk of all hornless dun cows, the cows of Ireland were passed through fire and smeared with ashes—a myth based perhaps on the Beltane fire ritual.120 The avaricious Bres was satirised, and "nought but decay was on him from that hour,"121
