Then Math son of Mathonwy took one and baptised him Dylan. The boy grew up to love the sea and became a fisherman, and for that reason he was called Dylan Eil Ton, sea son of the wave. The blow whereby his death came was from his uncle Gofannon, and that at the mouth of the Conway.
Gwydion took the smaller boy and wrapped him in a sheet of silk. Then he carried him to the town, where he knew there was a woman who had breasts, and he made a bargain with the woman to suckle the child.

When he was a big boy and able to go by himself to the court, Gwydion gave heed to him, and the boy grew used to Gwydion and loved him better than any one. Then the boy was reared at court.
