yule log! a collapsed pillar! I wonder if part of the celebration of acknowledgement of the yule log is to remind us of some temple being destroyed?
But what tool do you think the ancients used to find winter solstice? They became beyond our comprehension of the motions of shadows. They used Pillars to measure even small changes in shadows. A yule log is a fallen pillar. East of Stonehenge is woodhendge; many wood type structures can be found east of stone structures.
