Editing Dylan ail Don (section)

==Biography==
In ''Math fab Mathonwy'' it is told that Dylan's great uncle [[Math fab Mathonwy|Math]] would die if he did not keep his feet in the lap of a virgin when not at war. Math's original foot-holder, [[Goewin]], is raped by [[Gilfaethwy]] who is punished severely when Math returns, turning Gilfaethwy and [[Gwydion]] into a series of mated pairs of animals. Math then marries Goewin to alleviate her shame, but must find a new virgin to hold his feet. Gwydion suggests his sister, [[Arianrhod]].  Math magically tests Arianrhod to confirm that she is a virgin, at which point she gives birth to twin sons.<ref name=":1">{{Cite book |last=Unknown |title=The Mabinogion |publisher=[[Gutenberg press]] |year=2002 |others=eBook #5160 |edition=Trans.

===Dylan's baptism===
One of the sons, [[Lleu Llaw Gyffes]], is borne away by Gwydion as a "lump of flesh" and concealed in a chest until maturity, but the other, a sturdy blonde boy, was immediately forsaken by his mother yet was acknowledged by his great uncle Math and given the name Dylan.  As soon as Dylan comes in contact with his baptismal waters, he plunges into the sea and takes on characteristics of a sea creature, moving through the seawater as perfectly as any fish:<ref name=":1" />
<blockquote>
'So they had the boy baptised, and as they baptised him he plunged into the sea. And immediately when he was in the sea, he took its nature, and swam as well as the best fish that was therein.  And for that reason was he called Dylan, the son of the Wave<ref name="Guest, 1877: Ch. 9">Guest, 1877: Chapter 9</ref>'
