This week, the Hersey reading was about columns, and the origins thereof. It was intriguing that they were started as trees - it is wondered if trees weren't even modified at the very beginning, but instead used as they were where they were. Over time, they were cut down and modified to hold up tarp like things, other sticks, etc. That basic shape was then taken and carved out of rock for what we recognize as columns now. They became more decorative over time, and are now used for a little bit of everything.
