The modern Christmas tree can easily be traced back to seventeenth century Germany; branches of holly and mistletoe were likewise displayed. Not only did these plants remain green through the winter months, but they also bore fruit at that time, thus symbolizing life in an otherwise dead season.
So you appear to admit that Christmas trees are a development far too late for any ancient pagan customs to have any influence on them. I'm glad you were apparently willing to admit that.
However, you then pivot to something new, which has its own new problems:
Many of our present Christmas traditions and symbols have historical roots in ancient paganistic rites related to Celtic, Druid, Roman or Nordic. Druid ceremonies were based on an eight-fold year. Four were solar and the other four were lunar. The Yule celebration is Dec. 22 or Winter Solstice. Yule is one of the eight festival days of the pagans. The Roman and Nordic invaders of Ireland had an influence on the prominence and significance of Yule. Yule, in both old Roman paganism and in Norse tradition, was the start of the New Year. Yule comes from a Nordic word meaning "wheel." The Christmas wreath is a symbol of the wheel of the year. Yule altars throughout paganism show the influence of Ireland and the Druids with their holly, pine and mistletoe coverings. Yule rituals enact birthing rites, ask for the sun god's return, and beseech that the wheel of the year be turned again.
The very word "Druid" means wise man of the oak, or "One who has knowledge of the oak." The custom of lighting a Yule log is an ancient Druid practice. A log, usually of the god-related oak tree, is carved into a small section which is brought into a dwelling. Holes are drilled into the log and candies inserted. The entire log is then decoratively covered with holly and evergreens to represent the intertwining of god and goddess, or male and female elements. Hopes for fertile crops, herds, and families are invested in the Yule log image.
Consider the habit of putting up lights. The profusion of lights on house and tree at Christmas time is a carry-over of the candles and fires lit in sympathetic magic to lure back the waning sun. Today it's still an Irish custom to leave lights burning all through the house on midwinter night to honor the sun's return. Fires and lights, symbols of warmth and lasting life, have always been associated with the winter solstice festival of the pagans.
You make these assertions, but cite no evidence. Our information about the druids is rather scanty, and if you have evidence for these, it might be good to notify historians so they do. Or, at least, share it with us, for these claims seem very questionable. So, point us to the primary sources that affirm the things you describe. Because if there aren't primary sources, then that would mean this is just a bunch of nonsense from other people that you're uncritically repeating.
Let's take one example. You claim:
"The custom of lighting a Yule log is an ancient Druid practice. A log, usually of the god-related oak tree, is carved into a small section which is brought into a dwelling. Holes are drilled into the log and candies inserted. The entire log is then decoratively covered with holly and evergreens to represent the intertwining of god and goddess, or male and female elements. Hopes for fertile crops, herds, and families are invested in the Yule log image."
No primary source--or any source at all--is provided by you. I strongly suspect there is no such source, and this is totally made up. I say this for two reasons.
First, you claim this was a Druid practice. But the Druids seem to have largely faded away by the 2nd century AD under Roman occupation. Yule was a term for winter that came to Britain with the Anglo-Saxons, who arrived in the 5th century. How precisely would the Druids have been engaging in anything related to Yule when it hadn't even been introduced yet?
Second, even if we were to ignore that and ask about the Yule Log solely, we run into a larger problem. Despite the common claim, there is as far as I can tell a paucity of evidence there was ever any pagan practice of a "Yule Log". Most likely there were pagans who used logs as firewood, but that doesn't mean they attached any
religious importance to them, much less that "the entire log is then decoratively covered with holly and evergreens to represent the intertwining of god and goddess, or male and female elements". As far as I can tell, the term "Yule Log" first appeared in the 17th century in a reference to
Christmas customs (certainly, I have seen no one point to an earlier usage). While there are earlier instances of the log's usage described without that specific name, all of the ones I can find are in reference to
Christmas, not any pagan practice. The idea that this had a connection to an earlier pagan Yule celebration appears to have been the invention of later writers who saw "Yule Log" and
assumed it had a pagan origin based on the name, despite the apparent lack of any actual attestation to such a thing, and the apparent inability of anyone to point to evidence of it. Even the (speculative) ideas I've seen pointed to for possible evidence of pagans practicing such a thing fall very well short of any reference that "the entire log is then decoratively covered with holly and evergreens to represent the intertwining of god and goddess, or male and female elements" as you claimed.
If you indeed do have primary sources attesting to these claims of yours (rather than this just being you copying a bunch of incorrect information from others), it would be quite appreciated if you would provide it.
