Editing Lleu Llaw Gyffes (section)

===Lleu and 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 uses an unspecified missile to strike 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|wlm|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:
