Aonghus held splendid court at Newgrange. But one night he was visited in a dream by a beautiful maiden, who vanished when he put out his arms to embrace her. All the next day Aonghus took no food. Upon the following night, the fair apparition came again, and played and sang to him. That following day he also fasted. So things went on like that for a year, while Aonghus pined and wasted for love. Eventually the physicians of the Tuatha prevailed upon him to act, his mother the goddess Bóinn was sent for, and she persuaded the Dagdha, his father, to send to all the lesser deities of Ireland, charging them to search for her. After a year she was found by Aonghus's brother, Bodbh the Red, who brought him to see her. Her name was Caer Ibormeith, meaning Yew Berry; and when Aonghus saw her, she was standing by a lake surrounded by thrice fifty maidens linked together by a silver chain. But when Aonghus asked her Father for her hand in marriage he revealed that there was nothing he could do, as his daughter was a swan-maiden, and every year as soon as summer was over, she went with her companions to a lake called Lough Dragan, 'The Mouth of Sloes', and all of them became swans. On the advice of the Dagdha, Aonghus went to the shore of the lake and waited in patience until "Samhain", the day of the magical change, and called to her. Caer appeared along with thrice fifty swans, herself a swan surpassing all the rest in beauty and whiteness, and promised to be his bride, if he too would become a swan. He agreed , and with aword she changed him into a swan. Together they flew three times around the lake, and took off sideby side for Brugh na Bóinne where they put the dwellers of that place to sleep for three days and three nights with the magic of their singing. At Aonghus's palace they retook the human form, and theyhave lived happily there ever since.
