Long ago there dwelt in Ireland the race called by the name of De Danaan, or People of the Goddess Dana. They were a folk who delighted in beauty and gaiety, and in fighting and feasting, and loved to go gloriously apparelled, and to have their weapons and household vessels adorned with jewels and gold. They were also skilled in magic arts, and their harpers could make music so enchanting that a man who heard it would fight, or love, or sleep, or forget all earthly things, as they who touched the strings might will him to do. In later times the Danaans had to dispute the sovranty of Ireland with another race, the Children of Miled, whom men call the Milesians, and after much fighting they were vanquished. Then, by their sorceries and enchantments, when they could not prevail against the invaders, they made themselves invisible, and they have dwelt ever since in the Fairy Mounds and raths of Ireland, where their shining palaces are hidden from mortal eyes. They are now called the Shee, or Fairy Folk of Erinn, and the faint strains of unearthly music that may be heard at times by those who wander at night near to their haunts come from the harpers and pipers who play for the People of Dana at their revels in the bright world underground.

At the time when the tale begins, the People of Dana were still the lords of Ireland, for the Milesians had not yet come. They were divided it is said, into many families and clans; and it seemed good to them that their chiefs should assemble together, and choose one to be king and ruler over the whole people. So they met in a great assembly for this purpose, and found that five of the greatest lords all desired the sovranty of Erin. These five were B—v the Red, and Ilbrech of Assaroe, and Lir from the Hill of the White Field, which is on Slieve Fuad in Armagh; and Midir the Proud, who dwelt at Slieve Callary in Longford; and Angus of Brugh na Boyna, which is now Newgrange on the river Boyne, where his mighty mound is still to be seen. All the Danaan lords saving these five went into council together, and their decision was to give the sovranty to B—v the Red, partly because he was the eldest, partly because his father was the Dagda, mightiest of the Danaans, and partly because he was himself the most deserving of the five.

All were content with this, save only Lir, who thought himself the fittest for royal rule; so he went away from the assembly in anger, taking leave of no one. When this became known, the Danaan lords would have pursued Lir, to burn his palace and inflict punishment and wounding on himself for refusing obedience and fealty to him whom the assembly had chosen to reign over them. But B—v the Red forbade them, for he would not have war among the Danaans; and he said, "I am none the less King of the People of Dana because this man will not do homage to me."

Thus it went on for a long time. But at last a great misfortune befell Lir, for his wife fell ill, and after three nights she died. Sorely did Lir grieve for this, and he fell into a great dejection of spirit, for his wife was very dear to him and was much thought of by all folk, so that her death was counted one of the great events of that time.
