The British Museum has recently purchased a medieval astronomy tool that used for several hundred years until they came up with something better. What I found especially interesting were the symbols involved with the tool that helped identify this object as what it was. For example: Archaeologists knew it was supposed to track the sun because it had an eagle stamped on it, a creature rumored at the time to be able to look directly at the sun. While I would never wish medieval Europe on anyone, I’ve always liked the intersection of art and science from that era (although I don’t really like the intersection of the church and science. Spanish Inquisition? I’ll pass).
