The story opens with a conversation between Mève, queen of Connacht, and Oilioll her husband, which ends in a dispute as to which of them is the richest. There was no modern Married Women's Property Act in force, but Irish ladies seem to have been at all times much more sympathetically treated by the Celtic tribes than by the harder and more stern races of Teutonic and Northern blood, and Irish damsels seem to have been free to enjoy their own property and dowries.[2] The story, then, begins with this dispute as to which, husband or wife, is the richer in this world's goods, and the argument at last becomes so heated that the pair decide to have all their possessions brought together to compare them one with another and judge by actual observation which is the most valuable. They collected accordingly jewels, bracelets, metal, gold, silver, flocks, herds, ornaments, etc., and found that in point of wealth they were much the same, but that there was one great bull called Finn-bheannach or White-horned, who was really calved by one of Mève's cows, but being endowed with a certain amount of intelligence considered it disgraceful to be under a woman, and so had gone over to Oilioll's herds. With him Mève had nothing that could compare. She made inquiry, however, and found out from her chief courier that there was in the district of Cuailgne in Louth (Mève lived at Rathcroghan in Roscommon) a most celebrated bull called the Dun Bull of Cuailgne belonging to a chieftain of the name of Darè. To him accordingly she sends an embassy requesting the loan of the bull for one year, and promising fifty heifers in return. Darè was quite willing, and promised to lend the animal. He was in fact pleased, and treated the embassy generously, giving them good lodgings with plenty of food and drink—too much drink in fact. The fate of nations is said to often hang upon a thread. On this occasion that of Ulster and Connacht depended upon a drop more or less, absorbed by one of the ten men who constituted Mève's embassy. This man unfortunately passed the just limit, and Darè's steward coming in at the moment heard him say that it was small thanks to his master to give his bull "for if he hadn't given it we'd have taken it." That word decided the fate of provinces. The steward, indignant at such an outrage, ran and told his master, and Darè swore that now he would lend no bull, and what was more, but that the ten men were envoys he swore he would hang them. With indignity they were dismissed, and returned empty-handed to Mève's boundless indignation. She in her turn swore she would have the bull in spite of Darè. She immediately sent out to collect her armies, and invited Leinster and Munster to join her. She was in fact able to muster most of the three provinces to march against Ulster to take the bull from Darè, and in addition she had Fergus mac Roy and about fifteen hundred Ulster warriors who had never returned to their homes nor forgiven Conor for the murder of the sons of Usnach. She crossed the Shannon at Athlone, and marched on to Kells, within a few miles of Ulster, and there she pitched her standing camp. She was accompanied by her husband and her daughter who was the fairest among women. Her mother had secretly promised her hand to every leader in her army in order to nerve them to do their utmost.
At the very beginning Mève is forewarned by a mysterious female of the slaughter which is to come. She had driven round in her chariot to visit her druid and to inquire of him what would come of her expedition, and is returning somewhat reassured in her mind by the druid's promise which was—
"'Whosoever returneth or returneth not, thou shalt return,' and," says the saga, "as Mève returned again upon her track she beheld a thing which caused her to wonder, a single woman (riding) beside her, upon the pole of her chariot. And this is how that maiden was. She was weaving a border with a sword of bright bronze[3] in her right hand with its seven rings of red gold, and, about her, a spotted speckled mantle of green, and a fastening brooch in the mantle over her bosom. A bright red gentle generous countenance, a grey eye visible in her head, a thin red mouth, young pearly teeth she had. You would think that her teeth were a shower of white pearls flung into her head. Her mouth was like fresh coral? [partaing]. The melodious address of her voice and her speaking tones were sweeter than the strings of curved harp being played. Brighter than the snow of one night was the splendour of her skin showing through her garments, her feet long, fairy-like, with (well) turned nails. Fair yellow hair very golden on her. Three tresses of her hair round her head, one tress behind falling after her to the extremities of her ankles.
"Mève looks at her. 'What makest thou there, O maiden?' said Mève.
"'Foreseeing thy future for thee, and thy grief, thou who art gathering the four great provinces of Ireland with thee to the land of Ulster, to carry out the Táin Bo Chuailgne.'
"'And wherefore doest thou me this?" said Mève.
"'Great reason have I for it,' said the maiden. 'A handmaid of thy people (am I),' said she.
"'Who of my people art thou?' said Mève.
"'Féithlinn, fairy-prophetess of Rathcroghan, am I,' said she.
"'It is well, O Féithlinn, prophetess,' said Mève, 'and how seest thou our hosts?'
"'I see crimson over them, I see red,' said she.
"'Conor is in his sickness[4] in Emania,' said Mève, 'and messengers have reached me from him, and there is nothing that I dread from the Ultonians, but speak thou the truth, O Féithlinn, prophetess,' said Mève.
"'I see crimson, I see red,' said she.
"'Comhsgraidh Meann ... is in Innis Comhsgraidh in his sickness, and my messengers have reached me, and there is nothing that I fear from the Ultonians, but speak me truth, O Féithlinn, prophetess, how seest thou our host?'
"'I see crimson, I see red.'
"'Celtchar, son of Uitheachar, is in his sickness,' said Mève, 'and there is nothing I dread from the Ultonians, but speak truth, O Féithlinn, prophetess.'
"'I see crimson, I see red,' said she.
"' ...?' said Mève, 'for since the men of Erin will be in one place there will be disputes and fightings and irruptions amongst them, about reaching the beginnings or endings of fords or rivers, and about the first woundings of boars and stags, of venison, or matter of venery, speak true, O Féithlinn, prophetess, how seest thou our host? said Mève.
"'I see crimson I see red,' said she."
After this follows a long poem, wherein "she foretold Cuchulain to the men of Erin."
The march of Mève's army is told with much apparent exactness. The names of fifty-nine places through which it passed are given; and many incidents are recorded, one of which shows the furious, jealous, and vindictive disposition of the amazon queen herself. She, who seems to have taken upon herself the entire charge of the hosting, had made in her chariot the full round of the army at their encamping for the night, to see that everything was in order. After that she returned to her own tent and sat beside her husband Olioill at their meal, and he asks her how fared the troops. Mève then said something laudatory about the Gaileóin,[5] or ancient Leinstermen, who were not of Gaelic race, but appear to have belonged to some early non-Gaelic tribe, cognate with the Firbolg.
"'What excellence perform they beyond all others that they be thus praised?' said Oilioll.
"'They give cause for praise,' said Mève, 'for while others were choosing their camping-ground, they had made their booths and shelters; and while others were making their booths and shelters, they had their feast of meat and ale laid out; and while others were laying out their feasts of bread and ale, these had finished their food and fare; and while others were finishing their food and fare, these were asleep. Even as their slaves and servants have excelled the slaves and servants of the men of Erin, so will their good heroes and youths excel the good heroes and youths of the men of Erin in this hosting.'
"'I am the better pleased at that,' said Oilioll, 'because it was with me they came, and they are my helpers.'[6]
"'They shall not march with thee, then,' said Mève, 'and it is not before me, nor to me, they shall be boasted of.'
"'Then let them remain in camp,' said Oilioll.
"'They shall not do that either,' said Mève.
"'What shall they do, then?' said Findabar, daughter of Oilioll and Mève, 'if they shall neither march nor yet remain in camp.'
"'My will is to inflict death and fate and destruction on them,' said Mève."
It is with the greatest difficulty that Fergus is enabled to calm the furious queen, and she is only satisfied when the three thousand Gaileóins have been broken up and scattered throughout the other battalions, so that no five men of them remained together.
Thereafter the army came to plains so thickly wooded, in the neighbourhood of the present Kells, that they were obliged to cut down the wood with their swords to make a way for their chariots, and the next night they suffered intolerably from a fall of snow.
"The snow that fell that night reached to men's legs and to the wheels of chariots, so that the snow made one plain of the five provinces of Erin, and the men of Ireland never suffered so much before in camp, none knew throughout the whole night whether it was his friend or his enemy who was next him, until the rise early on the morrow of the clear-shining sun, glancing on the snow that covered the country."
They are now on the borders of Ulster, and Cuchulain is hovering on their flank, but no one has yet seen him. He lops a gnarled tree, writes an Ogam on it, sticks upon it the heads of three warriors he had slain, and sets it up on the brink of a ford. That night Oilioll and Mève inquire from the Ultonians who were in her army more particulars about this new enemy, and nearly a sixth part of the whole Táin is taken up by the stories which are then and there related about Cuchulain's earliest history and exploits, first by Fergus, and, when he is done relating, by Cormac Conlingeas, and when he has finished, by Fiacha, another Ultonian. This long digression, which is one of the most interesting parts of the whole saga, being over, we return to the direct story.
