Just as Saturnalia was a major Solstice celebration for southern Europe, so was Yuletide in the north. The word Yule was the name of the time period now divided into December & January. It involved bringing into your home: ivy, holly, mistletoe
& a tree to be decorated in honor of Odin.
Odin gained knowledge & transcended death
after being hung from a tree - instead of a cross. A Yule log was burned in honor of Thor. You can't cut a tree down for this; you have to find a fallen log that will burn for days. Over the Yule log's fire is cooked a boar (in honor
of Freyr) for the community to feast upon.
