This is very old stuff though - pagan traditions and rituals that we were messing about with before the Romans turned up, never mind Christianity. Keeping the fire in for twelve days, an Oak Yule log, having a good scoff in the middle of the darkest part of the year, bringing greenery in to the house, the exchanging of gifts ..
I seem to remember reading something about the death of the Oak King and the crowning of the Holly King ... a line drawn between deciduous summer and evergreen winter on the longest night I guess. The Spruce Christmas tree may be a Victorian German import but we've been bringing green stuff into houses here for quite a bit before that. A Kissing bough for instance done up in evergreen finery. All that remains of it now is the Mistletoe, which must have turned out to be the active ingredient.
There's been cross dressing from early on too; not just in modern pantomime and not just cross gender either - "kings as fools" and vice versa for instance.
When the Romans arrived they brought their own pagan winter solstice traditions. Saturnalia was a day of drinking, feasting and vomiting that took place on the 25th of December ... sounds familiar.
I think it's from the Roman menu of Yule that we get all the things we were s'posed to eat on the different days - birds inside birds etc.
The Romans brought apples and the possibility of cider but we had probably been Wassailing the oldest tree in the Pear orchard before that, putting perry soaked toast in its branches to "toast" the spirit of the wood "Robin" Red Breast, Robin of the Green, Puck, that Gentleman of Winter in his red robe ... and to feed the tree with Perry while drinking mere ale ourselves. That's what I call a pagan sacrifice.
It gives me hope that despite everything that we appear to have lost, skills, communal spirit, common sense etc; that we still do all this stuff around the solstice - maybe we only observe the shadow of what these things once meant but we are aware of it nevertheless. We even still call it Yule.
A bit of Celt, a bit of Druid, Saxon, Roman and Christian.
The Christian church came and put its buildings next to our evergreen Yew trees with their red baubles and put its Holy days smack on the top of our existing holidays. From The Roman Empire to Holy Roman Empire, through the dark ages, feudalism, reformation, democracy and Thatcherism .. Saturnalia has stayed put; along with everything else we've ever done around the solstice.
Mine's a large Perry. :ho2
