It was in a mist the Tuatha de Danaan, the people of the gods of Dana, or as some called them, the Men of Dea, came through the air and the high air to Ireland.
It was from the north they came; and in the place they came from they had four cities, where they fought their battle for learning: great Falias, and shining Gorias, and Finias, and rich Murias that lay to the south. And in those cities they had four wise men to teach their young men skill and knowledge and perfect wisdom: Senias in Murias; and Arias, the fair-haired poet, in Finias; and Urias of the noble nature in Gorias; and Morias in Falias itself. And they brought from those four cities their four treasures: a Stone of Virtue from Falias, that was called the Lia Fail, the Stone of Destiny; and from Gorias they brought a Sword; and from Finias a Spear of Victory; and from Murias the fourth treasure, the Cauldron that no company ever went away from unsatisfied.
It was Nuada was king of the Tuatha de Danaan at that time, but Manannan, son of Lir, was greater again. And of the others that were chief among them were Ogma, brother to the king, that taught them writing, and Diancecht, that understood healing, and Neit, a god of battle, and Credenus the Craftsman, and Goibniu the Smith. And the greatest among their women were Badb, a battle goddess; and Macha, whose mast-feeding was the heads of men killed in battle; and the Morrigu, the Crow of Battle; and Eire and Fodla and Banba, daughters of the Dagda, that all three gave their names to Ireland afterwards; and Eadon, the nurse of poets; and Brigit, that was a woman of poetry, and poets worshipped her, for her sway was very great and very noble. And she was a woman of healing along with that, and a woman of smith's work, and it was she first made the whistle for calling one to another through the night. And the one side of her face was ugly, but the other side was very comely. And the meaning of her name was Breo-saighit, a fiery arrow. And among the other women there were many shadow-forms and great queens; but Dana, that was called the Mother of the Gods, was beyond them all.
And the three things they put above all others were the plough and the sun and the hazel-tree, so that it was said in the time to come that Ireland was divided between those three, Coll the hazel, and Cecht the plough, and Grian the sun.
And they had a well below the sea where the nine hazels of wisdom were growing; that is, the hazels of inspiration and of the knowledge of poetry. And their leaves and their blossoms would break out in the same hour, and would fall on the well in a shower that raised a purple wave. And then the five salmon that were waiting there would eat the nuts, and their colour would come out in the red spots of their skin, and any person that would eat one of those salmon would know all wisdom and all poetry. And there were seven streams of wisdom that sprang from that well and turned back to it again; and the people of many arts have all drank from that well.
It was on the first day of Beltaine, that is called now May Day, the Tuatha de Danaan came, and it was to the north-west of Connacht they landed. But the Firbolgs, the Men of the Bag, that were in Ireland before them, and that had come from the South, saw nothing but a mist, and it lying on the hills.
Eochaid, son of Erc, was king of the Firbolgs at that time, and messengers came to him at Teamhair, and told him there was a new race of people come into Ireland, but whether from the earth or the skies or on the wind was not known, and that they had settled themselves at Magh Rein.
They thought there would be wonder on Eochaid when he heard that news; but there was no wonder on him, for a dream had come to him in the night, and when he asked his Druids the meaning of the dream, it is what they said, that it would not be long till there would be a strong enemy coming against him.
Then King Eochaid took counsel with his chief advisers, and it is what they agreed, to send a good champion of their own to see the strangers and to speak with them. So they chose out Sreng, that was a great fighting man, and he rose up and took his strong red-brown shield, and his two thick-handled spears, and his sword, and his head-covering, and his thick iron club, and he set out from Teamhair, and went on towards the place the strangers were, at Magh Rein.
But before he reached it, the watchers of the Tuatha de Danaan got sight of him, and they sent out one of their own champions, Bres, with his shield and his sword and his two spears, to meet him and to talk with him.
So the two champions went one towards the other slowly, and keeping a good watch on one another, and wondering at one another's arms, till they came near enough for talking; and then they stopped, and each put his shield before his body and struck it hard into the ground, and they looked at one another over the rim. Bres was the first to speak, and when Sreng heard it was Irish he was talking, his own tongue, he was less uneasy, and they drew nearer, and asked questions as to one another's family and race.
And after a while they put their shields away, and it was what Sreng said, that he had raised his in dread of the thin, sharp spears Bres had in his hand. And Bres said he himself was in dread of the thick-handled spears he saw with Sreng, and he asked were all the arms of the Firbolgs of the same sort. And Sreng took off the tyings of his spears to show them better, and Bres wondered at them, being so strong and so heavy, and so sharp at the sides though they had no points. And Sreng told him the name of those spears was Craisech, and that they would break through shields and crush flesh and bones, so that their thrust was death or wounds that never healed. And then he looked at the sharp, thin, hard-pointed spears that were with Bres. And in the end they made an exchange of spears, the way the fighters on each side would see the weapons the others were used to. And it is the message Bres sent to the Firbolgs, that if they would give up one half of Ireland, his people would be content to take it in peace; but if they would not give up that much, there should be a battle. And he and Sreng said to one another that whatever might happen in the future, they themselves would be friends.
Sreng went back then to Teamhair and gave the message and showed the spear; and it is what he advised his people, to share the country and not to go into battle with a people that had weapons so much better than their own. But Eochaid and his chief men consulted together, and they said in the end: "We will not give up the half of the country to these strangers; for if we do," they said, "they will soon take the whole."
Now as to the Men of Dea, when Bres went back to them, and showed them the heavy spear, and told them of the strong, fierce man he had got it from, and how sturdy he was and well armed, they thought it likely there would soon be a battle. And they went back from where they were to a better place, farther west in Connacht, and there they settled themselves, and made walls and ditches on the plain of Magh Nia, where they had the great mountain, Belgata, in their rear. And while they were moving there and putting up their walls, three queens of them, Badb and Macha and the Morrigu, went to Teamhair where the Firbolgs were making their plans. And by the power of their enchantments they brought mists and clouds of darkness over the whole place, and they sent showers of fire and of blood over the people, the way they could not see or speak with one another through the length of three days. But at the end of that time, the three Druids of the Firbolgs, Cesarn and Gnathach and Ingnathach, broke the enchantment.
The Firbolgs gathered their men together then, and they came with their eleven battalions and took their stand at the eastern end of the plain of Magh Nia.
And Nuada, king of the Men of Dea, sent his poets to make the same offer he made before, to be content with the half of the country if it was given up to him. King Eochaid bade the poets to ask an answer of his chief men that were gathered there; and when they heard the offer they would not consent. So the messengers asked them when would they begin the battle. "We must have a delay," they said; "for we want time to put our spears and our armour in order, and to brighten our helmets and to sharpen our swords, and to have spears made like the ones you have. And as to yourselves," they said, "you will be wanting to have spears like our Craisechs made for you." So they agreed then to make a delay of a quarter of a year for preparation.
It was on a Midsummer day they began the battle. Three times nine hurlers of the Tuatha de Danaan went out against three times nine hurlers of the Firbolgs, and they were beaten, and every one of them was killed. And the king, Eochaid, sent a messenger to ask would they have the battle every day or every second day. And it is what Nuada answered that they would have it every day, but there should be just the same number of men fighting on each side. Eochaid agreed to that, but he was not well pleased, for there were more men of the Firbolgs than of the Men of Dea.
So the battle went on for four days, and there were great feats done on each side, and a great many champions came to their death. But for those that were alive at evening, the physicians on each side used to make a bath of healing, with every sort of healing plant or herb in it, the way they would be strong and sound for the next day's fight.
And on the fourth day the Men of Dea got the upper hand, and the Firbolgs were driven back. And a great thirst came on Eochaid, their king, in the battle, and he went off the field looking for a drink, and three fifties of his men protecting him; but three fifties of the Tuatha de Danaan followed after them till they came to the strand that is called Traigh Eothaile, and they had a fierce fight there, and at the last King Eochaid fell, and they buried him there, and they raised a great heap of stones over his grave.
And when there were but three hundred men left of the eleven battalions of the Firbolgs, and Sreng at the head of them, Nuada offered them peace, and their choice among the five provinces of Ireland. And Sreng said they would take Connacht; and he and his people lived there and their children after them. It is of them Ferdiad came afterwards that made such a good fight against Cuchulain, and Erc, son of Cairbre, that gave him his death. And that battle, that was the first fought in Ireland by the Men of Dea, was called by some the first battle of Magh Tuireadh.
And the Tuatha de Danaan took possession of Teamhair, that was sometimes called Druim Cain, the Beautiful Ridge, and Liathdruim, the Grey Ridge, and Druim na Descan, the Ridge of the Outlook, all those names were given to Teamhair. And from that time it was above all other places, for its king was the High King over all Ireland. The king's rath lay to the north, and the Hill of the Hostages to the north-east of the High Seat, and the Green of Teamhair to the west of the Hill of the Hostages. And to the north-east, in the Hill of the Sidhe, was a well called Nemnach, and out of it there flowed a stream called Nith, and on that stream the first mill was built in Ireland.
And to the north of the Hill of the Hostages was the stone, the Lia Fail, and it used to roar under the feet of every king that would take possession of Ireland. And the Wall of the Three Whispers was near the House of the Women that had seven doors to the east, and seven doors to the west; and it is in that house the feasts of Teamhair used to be held. And there was the Great House of a Thousand Soldiers, and near it, to the south, the little Hill of the Woman Soldiers.
