Whether the Tuatha Dé Danann came from earth or heaven, they landed in a dense cloud upon the coast of Ireland on the mystic first of May without having been opposed, or even noticed by the people whom it will be convenient to follow the manuscript authorities in calling the “Fir Bolgs”.[[104]] That those might still be ignorant of their coming, the Morrígú, helped by Badb and Macha, made use of the magic they had learned in Findias, Gorias, Murias, and Falias. They spread “druidically-formed showers and fog-sustaining shower-clouds” over the country, and caused the air to pour down fire and blood upon the Fir Bolgs, so that they were obliged to shelter themselves for three days and three nights. But the Fir Bolgs had druids of their own, and, in the end, they put a stop to these enchantments by counter-spells, and the air grew clear again.

The Tuatha Dé Danann, advancing westward, had reached a place called the “Plain of the Sea”, in Leinster, when the two armies met. Each sent out a warrior to parley. The two adversaries approached each other cautiously, their eyes peeping over the tops of their shields. Then, coming gradually nearer, they spoke to one another, and the desire to examine each other’s weapons made them almost friends.

The envoy of the Fir Bolgs looked with wonder at the “beautifully-shaped, thin, slender, long, sharp-pointed spears” of the warrior of the Tuatha Dé Danann, while the ambassador of the tribe of the goddess Danu was not less impressed by the lances of the Fir Bolgs, which were “heavy, thick, pointless, but sharply-rounded”. They agreed to exchange weapons, so that each side might, by an examination of them, be able to come to some opinion as to its opponent’s strength. Before parting, the envoy of the Tuatha Dé Danann offered the Fir Bolgs, through their representative, peace, with a division of the country into two equal halves.

The Fir Bolg envoy advised his people to accept this offer. But their king, Eochaid, son of Erc, would not. “If we once give these people half,” he said, “they will soon have the whole.”

The people of the goddess Danu were, on the other hand, very much impressed by the sight of the Fir Bolgs’ weapons. They decided to secure a more advantageous position, and, retreating farther west into Connaught, to a plain then called Nia, but now Moytura, near the present village of Cong, they drew up their line at its extreme end, in front of the pass of Balgatan[[105]], which offered a retreat in case of defeat.

The Fir Bolgs followed them, and encamped on the nearer side of the plain. Then Nuada, King of the Tuatha Dé Danann, sent an ambassador offering the same terms as before. Again the Fir Bolgs declined them.

“Then when”, asked the envoy, “do you intend to give battle?”

“We must have a truce,” they said, “for we want time to repair our armour, burnish our helmets, and sharpen our swords. Besides, we must have spears like yours made for us, and you must have spears like ours made for you.”

The result of this chivalrous, but, to modern ideas, amazing, parley was that a truce of one hundred and five days was agreed upon.

It was on Midsummer Day that the opposing armies at last met. The people of the goddess Danu appeared in “a flaming line”, wielding their “red-bordered, speckled, and firm shields”. Opposite to them were ranged the Fir Bolgs, “sparkling, brilliant, and flaming, with their swords, spears, blades, and trowel-spears”. The proceedings began with a kind of deadly hurley-match, in which thrice nine of the Tuatha Dé Danann played the same number of the Fir Bolgs, and were defeated and killed. Then followed another parley, to decide how the battle should be carried on, whether there should be fighting every day or only on every second day. Moreover, Nuada obtained from Eochaid an assurance that the battles should always be fought with equal numbers, although this was, we are told, “very disagreeable to the Fir Bolg king, because he had largely the advantage in the numbers of his army”. Then warfare recommenced with a series of single combats, like those of the Greeks and Trojans in the “Iliad”. At the end of each day the conquerors on both sides went back to their camps, and were refreshed by being bathed in healing baths of medicinal herbs.
