Editing Gwydion (section)

==Mythological exploits==

===War with the South===
[[Gilfaethwy]], nephew to the [[Kingdom of Gwynedd|Venedotian]] king, [[Math fab Mathonwy]], becomes obsessed with his uncle's [[virgin]] foot-holder, [[Goewin]]. His brother Gwydion conspires to start a war between the [[North Wales|north]] and the [[South Wales|south]]. To this end, Gwydion employs his magic powers to steal a number of [[Annwn|otherworldly]] pigs from the [[Kingdom of Dyfed|Demetian]] king, [[Pryderi]], who retaliates by marching on Gwynedd. During the war, while Math is distracted, the brothers return home and Gilfaethwy rapes Goewin.<ref>{{Cite web|url=http://www.maryjones.us/jce/gwydion.html|title = Gwydion}}</ref>

Pryderi and his men march north and fight a battle between Maenor Bennardd and Maenor Coed Alun, but are forced to retreat. He is pursued to Nant Call, where more of his men are slaughtered, and then to Dol Benmaen, where he suffers a third defeat. To avoid further bloodshed, it is agreed that the outcome of the battle should be decided by [[single combat]] between Gwydion and Pryderi. The two contenders meet at a place called ''Y Velen Rhyd'' in [[Ardudwy]], and "because of strength and valour and magic and enchantment", Gwydion triumphs and Pryderi is killed. The men of Dyfed retreat back to their own land, lamenting over the death of their lord.

===Birth of Lleu===
When Math hears of the assault on Goewin, he [[Shapeshifting|turns]] his nephews into a series of mated pairs of animals: Gwydion becomes a [[stag]] for a year, then a [[pig|sow]] and finally a [[wolf]]. Gilfaethwy becomes a [[deer|hind]], a [[wild boar]] and a she-wolf. Each year they produce an offspring which is sent to Math: [[Hyddwn]], [[Hychddwn]] and [[Bleiddwn]]. After three years, Math releases his nephews from their punishment and begins the search for a new foot-holder. Gwydion suggests his sister [[Arianrhod]], who is magically tested for virginity by Math. During the test, she gives birth to a "sturdy boy with thick yellow hair" whom Math names [[Dylan ail Don|Dylan]] and who takes on the nature of the seas until his death at his uncle [[Gofannon]]'s hands.

Ashamed, Arianrhod runs to the door, but on her way out something small drops from her, which Gwydion wraps up and places in a chest at the foot of his bed. Some time later, he hears screams from within the chest, and opens it to discover a baby boy. Some scholars have suggested that in an earlier form of the Fourth Branch, Gwydion was the father of Arianrhod's sons.<ref name="MacKillop">MacKillop, ''Oxford Dictionary of Celtic Mythology'', p. 24.</ref>

===The ''tynghedau'' of Arianrhod===
Some years later, Gwydion accompanies the boy to Caer Arianrhod, and presents him to his mother. The furious Arianrhod, shamed by this reminder of her loss of virginity, places a ''[[tynged]]'' on the boy: that only she could give him a name. Gwydion however tricks his sister by disguising himself and the boy as cobblers and luring Arianrhod into going to them in person in order to have some shoes made for her. The boy throws a stone and strikes a wren "between the tendon and the bone of its leg", causing Arianrhod to make the remark "it is with a skillful hand that the fair-haired one has hit it ". At that Gwydion reveals himself, saying {{lang|mga|'''Lleu Llaw Gyffes'''}}; "the fair-haired one with the skillful hand," is his name now". Furious at this trickery, Arianrhod places another ''tynged'' on Lleu: he shall receive arms from no one but Arianrhod herself. Gwydion tricks his sister once again, and she unwittingly arms Lleu herself, leading to her placing a third ''tynged'' on him: that he shall never have a human wife.

So as to counteract Arianrhod's curse, Math and Gwydion:

{{cquote|[take] the flowers of the oak, and the flowers of the broom, and the flowers of the meadowsweet, and from those they conjured up the fairest and most beautiful maiden anyone had ever seen. And they baptized her in the way that they did at that time, and named her [[Blodeuwedd]].}}

===Lleu's death and resurrection===
Blodeuwedd has an affair with [[Gronw Pebr]], the lord of [[Penllyn (cantref)|Penllyn]], and the two conspire to murder Lleu. Blodeuwedd tricks Lleu into revealing how he may be killed, since he can not be killed during the day or night, nor indoors or outdoors, neither riding nor walking, not clothed and not naked, nor by any weapon lawfully made.  He reveals to her that he can only be killed at dusk, wrapped in a net with one foot on a cauldron and one on a goat and with a spear forged for a year during the hours when everyone is at mass.  With this information she arranges his death.

Struck by the spear thrown by Gronw's hand, Lleu transforms into an [[eagle]] and flies away. Gwydion tracks him down and finds him perched high on an oak tree. Through the singing of an [[englyn]] (known as [[englyn Gwydion]]) he lures him down from the [[oak]] tree and switches him back to his human form.  Gwydion and Math nurse Lleu back to health before reclaiming his lands from Gronw and Blodeuwedd. In the face-off between Lleu and Gronw, Gronw asks if he may place a large stone between himself and Lleu's spear. Lleu allows him to do so, then throws his spear which pierces both the stone and Gronw, killing him. Gwydion corners Blodeuwedd and turns her into an [[owl]], the creature hated by all other birds. The tale ends with Lleu ascending to the throne of Gwynedd.

===The Battle of the Trees===
A large tradition seems to have once surrounded the [[Cad Goddeu|Battle of the Trees]], a mythological conflict fought between the sons of Dôn and the forces of [[Annwn]], the Welsh [[Otherworld]]. [[Amaethon]], Gwydion's brother, steals a white [[Roe Deer|roebuck]] and a [[Puppy|whelp]] from [[Arawn]], king of the otherworld, leading to a great battle.

Gwydion fights alongside his brother and, assisted by Lleu, enchants the "elementary trees and sedges" to rise up as warriors against Arawn's forces. The [[alder]] leads the attack, while the [[aspen]] falls in battle, and heaven and earth tremble before the [[oak]], a "valiant door keeper against the enemy". The [[Hyacinthoides non-scripta|bluebells]] combine and cause a "consternation" but the hero is the [[holly]], tinted with green.

A warrior fighting alongside Arawn cannot be vanquished unless his enemies can guess his name. Gwydion guesses the warrior's name, identifying him from the sprigs of alder on his shield, and sings two [[englyn]]s:

:"Sure-hoofed is my steed impelled by the spur;
:The high sprigs of alder are on thy shield;
:[[Bendigeidfran|Bran]] art thou called, of the glittering branches."

:Sure-hoofed is my steed in the day of battle:
:The high sprigs of alder are on thy hand:
:Bran by the branch thou bearest
:Has Amathaon the good prevailed."

===Other traditions===
Caer Wydion, the castle of Gwydion, was the traditional Welsh name for the [[Milky Way]].<ref>{{Cite book|title=The Druid Magic Handbook: Ritual Magic Rooted in the Living Earth|last=Greer|first=John Michael|publisher=Weiser Books|year=2007|isbn=978-1-57863-397-5|location=San Francisco, CA}}</ref>

In the 10th century, Old Welsh "Harleian" genealogies (Harleian MS 3859), mention is made of Lou Hen ("Lou the old") map Guidgen, who most scholars identify with Lleu and Gwydion (who is implied to be Lleu's father in the Mabinogi of Math, though this relationship is not explicitly stated). In the genealogy they are made direct descendants Caratauc son of Cinbelin son of Teuhant (''recte Tehuant''), who are to be identified with the historical [[Catuvellauni]]an leaders [[Caratacus]], [[Cunobelinus]] and [[Tasciovanus]].

A number of references to Gwydion can be found in early [[Welsh language|Welsh]] poetry. The poem ''Prif Gyuarch Taliessin'' asks "Lleu and Gwydion / Will they perform magics?", while in the same corpus, the poem ''Kadeir Cerridwen'' relates many familiar traditions concerning Gwydion, including his creating of a woman out of flowers and his bringing of the pigs from the south. This poem also refers to a lost tradition concerning a battle between Gwydion and an unknown enemy at the [[Nant Ffrancon Pass|Nant Ffrangon]]. Another [[Taliesin]] poem, ''Echrys Ynys'' refers to [[Gwynedd]] as the "Land of Gwydion" while in the ''Ystoria Taliesin'', the legendary bard claims to have been present at Gwydion's birth "before the court of Don".

[[File:Dinas Dinlle 01 977.PNG|thumb|right|210px|[[Dinas Dinlle]], Gwydion's final resting place.]]
The [[Welsh Triads]] name Gwydion as one of the "Three Golden Shoemakers of the Island of Britain" alongside [[Manawydan|Manawydan fab Llyr]] and [[Caswallawn|Caswallawn fab Beli]], and records that Math taught him one of the "Three Great Enchantments". The ''[[Englynion y Beddau|Stanzas of the Graves]]'' record that he was buried at [[Dinas Dinlle]], the city of Lleu.

A reference to Gwydion is also made in the ''Dialogue of Taliesin and Ugnach'', a dialogue-poem found in the [[Black Book of Carmarthen]]. Within the narrative, the character of [[Taliesin]] states:

:"When I return from [[Jerusalem|Caer Seon]]
:From contending with Jews
:I will come to the city of Lleu and Gwydion."
