"After that, Ailill's household and the Dagdae's people rose up against the sid and destroyed it; they brought out three score heads and confined the king to Cr˙achu. Ailill said to Ethal Anb˙ail 'Give your daughter to the son of the Dagdae.' 'I cannot,' he said, 'for her power is greater than mine.' 'What great power does she have?' Ailill asked. 'Being in the form of a bird each day of one year and in human form each day of the following year,' Ethal said. 'Which year will she be in the shape of a bird?' Ailill asked. 'It is not for me to reveal that,' Ethal replied. 'Your head is off,' said Ailill, 'unless you tell us.' 'I will conceal it no longer, then, but will tell you, since you are so obstinate,' said Ethal. 'Next Samuin she will be in the form of a bird; she will be at Loch BÈl Dracon, and beautiful birds will be seen with her, three fifties of swans about her, and I will make ready for them.' 'No matter that,' said the Dagdae, 'since I know the nature you have brought upon her.'
Peace and friendship were made among Ailill and Ethal and the Dagdae, then, and the Dagdae bade them farewell and went to his house and told the news to his son. 'Go next Samuin to Loch BÈl Dracon,' he said, 'and call her to you there.' The Macc Oc went to Loch BÈl Dracon, and there he saw the three fifties of white birds, with silver chains, and golden hair about their heads. Oengus was in human form at the edge of the lake, and he called to the girl, saying 'Come and speak with me, C·er!' 'Who is calling to me?' sked C·er. 'Oengus is calling,' he replied. 'I will come,' she said, 'if you promise me that I may return to the water.' 'I promise that,' he said. She went to him, then: he put his arms round her, and they slept in the form of swans until they had circles the lake three times. Thus, he kept his promise. They left in the form of two white birds and flew to Bruig ind Maicc Oic, and there they sang until the people inside fell asleep for three days and three nights. The girl remained with Oengus after that. This is how the friendship between Ailill and Medb and the Macc Oc arose, and this is why Oengus took three hundred to the cattle raid of C˙ailnge. "
