When King Uther saw him, he said he was welcome.

Sir, said Merlin, I know all your heart every deal; so ye will be sworn unto me as ye be a true king anointed, to fulfil my desire, ye shall have your desire.

Then the king was sworn upon the Four Evangelists.

Sir, said Merlin, this is my desire: the first night that ye shall lie by Igraine ye shall get a child on her, and when that is born, that it shall be delivered to me for to nourish there as I will have it; for it shall be your worship, and the child's avail, as mickle as the child is worth.

I will well, said the king, as thou wilt have it.
