Blodeuwedd was created out of flowers by Gwydion to wed Llew Llaw Gyffes. She betrayed Llew, either because she had no soul, being non-human, or because she resented being his chattel, or because the triplet of one woman and two men must play itself out in Welsh myth, and Llew Llaw Gyffes must die. At any rate, she fell in love with Goronwy and, wishing to be rid of Llew, she tricked out of him the clearly supernatural and ritual manner in which only he could be killed: neither by day nor night, indoors nor out of doors, riding nor walking, clothed nor naked, nor by any weapon lawfully made. She asked him to explain this, and he did: he could be killed only if it were twilight, wrapped in a fish net, with one foot on a cauldron and the other on a goat, and if the weapon had been forged during sacred hours when such work was forbidden. Blodeuwedd convinced him to demonstrate how impossible such a position was to achieve by chance, and when he was in it, het lover Goronwy leapt out and struck. Llew was transformed into an eagle and eventually restored to human form, after which he killed Goronwy. Blodeuwedd was transformed into an owl, to haunt the night in loneliness and sorrow, shunned by all other birds.
