In the news is information about an astrologer's tool dating back over 2,000 years that was found in a cave in Croatia. It is a board consisting of ivory fragments, that when reconstructed showed a tool with the images of the zodiac. An astrologer would have used it to help prepare a horoscope.
This appears to be the oldest known example of such a tool, pre-dating any of the written horoscopes from the Greco-Roman World.
