For Lir and Bove Derg had vowed that henceforth they would live their years by the shores of Darvra, where they might converse with their dear ones, and where they might listen to the sweet oblivious songs which Fionula and her brothers sang to the easing of the heart, and the silence of all pain and weariness.

But so great was the rumour of this marvel that all Erin heard of it. The Milesians in the south agreed to a long truce of three hundred years; and came and dwelt in amity with the Dedannans, for they too loved the sweet and wonderful music of the white swans that were the children of Lir.

“Three hundred years yet may we live,” said Bove Derg to Lir, “and as I am a king, I swear never to leave the lough of Darvra while the four swans that are thy sons and daughter inhabit it. The heavy years shall pass for us, listening to their beautiful sweet singing; and therein we shall know peace and joy.”

“So be it,” said Lir, and he spoke the truth, for in that day the Dedannans lived to a great age; some say to three hundred, some to five, some to seven hundred years.

The years went by, one after the other, and by tens and by scores, and still Lir and Bove Derg and the Dedannans and Milesians dwelled by the shores of Lake Darvra. For never in the world’s history has there been chronicle of so sweet a singing as that of the four children of Lir. All day the swans discoursed lovingly with their father and Bove Derg, and their kith and kin, and all who sought them; and each night they sang their slow, sweet, fairy music—a music so wonderful and passing sweet, that all who listed to it forgot weariness and pain and bitter memories and the burden of years, and fell into a deep restful slumber, whence they awoke each morrow as though they had drunken overnight of the Fountain of Youth.

The hair of Lir and Bove Derg was long and white, and almost had the Dedannans and the Milesians forgotten their ancient enmity, when a day of the days came whereon Fionula called aside her three brothers.

“Dear brothers,” she said, as she looked sadly at the three beautiful white swans, and at the four drifting shadow-swans in the depths of the lake, “dear brothers, do you know that the time has come when we must put away our happiness as a dream that has been dreamed? For now the three hundred years of our sojourn here are at an end, and at dawn to-morrow we must arise and wing our sad flight across the dear lands of Erin, till we come to the wild and stormy waters of the sea-stream of the Moyle.”

Aed and Fiachra and Conn made so loud and bitter lamentation at this that all heard, and soon the whole host that was encamped there filled the region with long keening cries of grief, and a sorrowful mourning strain as of the melancholy wind among the hills.

But once more all were soothed that night into deep slumber and happy peace, because of the slow, sweet, fairy music of the chanting swans.

At dawn, the four swans arose, and with their white pinions circled high above the lake, glittering as they soared into the sunflood as it swept across the summits of the eastern hills.
