It seems that pagan is just a word that encompasses many of the earth religions such as wicca, celtic pagan, druids. There are more but I'm just learning.
In some pagan tales the oak king and the holly king fight for supremacy over the seasons. The Oak King rules the the Holly king represents the darkness of the old year where the Oak King represents the light of the new year. Each year they fight the battle to rule the seasons, but ofcourse the Oak King always wins!
Some say that the image of Santa Clause comes from the image of the green man.
I've always felt an affinity with the oak tree. For many years cezannes 'great oak' was my very favourite painting. After my mum died I would go for walks by ninewells and sit under the oak trees. It makes me feel so much better. Under any oak tree is my special place for consideration. It seems like the Oak king could be responsible for my wellbeing :) LINK TO ARTICLE
Druids and Wiccans speak of the horned god of the forest Cernunnos, the male partner of Earth Mother. Apparently he was such an important deity to celtic pagans that the christian church has adopted his horns and his status of guardian of the underworld as being the Christian devil.
"He is perhaps best known to us now in his Celtic aspects of the untamed Horned God of the Animals and the leaf-covered Green Man, Guardian of the Green World, but He is much older. Cernnunos worked his magic when the first humans were becoming. Our prehistoric ancestors knew him as a shape-shifting, shamanic god of the Hunt."

I found a nice page on Scottish (orkney) Yule traditions. Easy to read and cover quite a variety of stuff
