The Plant Dôn: the Children of Dôn, are introduced in the Fourth Branch of the Mabinogi. Who is Dôn, though? I have heard prominent people in contemporary Druidry describe Dôn as an earth goddess; I believe that they are mistaken, and that she is something quite different.
“There are the angels, and there are men, who Allah made from mud, and then there are the people of the fire, the jinn”, said Salim.

I wrote in an earlier post about the significance of red and green when we consider Gwyn ap Nudd. The green element in the clothes worn by his courtiers represents one of his domains: the forest. The red represents the Tylwyth Teg: the Fair Folk. The red is referred to in the Mabinogi, when Peredur finds the same symbolism in the Burning Tree. Here, we see the fire of Annwn – the flame of Awen that lights up our creativity, the hearth-fire that brings the Cauldron of Inspiration to the boil.
