The compass was developed into a compact design. Instead of balancing an iron spoon or floating a piece of magnetized iron in a bowl of water, compass designers suspended a magnetized iron arrow on a thin metal pin over a round card with directions displayed on it. The arrow and card were put in a round brass housing to protect them. Brass can’t be magnetized, so the housing didn’t interfere with the arrow’s attraction to the north pole.
Compass-makers put North, South, East and West (the cardinal directions) on their compass cards, then NorthNorthEast, NorthEast, EastNorthEast, EastSouthEast, SouthEast, SouthSouthEast, SouthSouthWest, SouthWest, WestSouthWest, WestNorthWest, NorthWest, NorthNorthWest and eventually all 32 points of direction.
Mapmakers began to indicate North on their maps so that you could line your map up with the compass’ arrow. This became the lovely compass rose you see on those gorgeous old maps.
You’re never lost if you have a map and a compass. Sea-farers were the first to use this technology but it works on land, too! There’s a scene in the movie The Big Country (it’s about a sea captain who decides to settle in the old American West) where sea-captain Gregory Peck goes exploring the countryside for a few days and all the ranchers are worried sick that he got lost in the desert. Everyone is relieved when he rides back to the ranch without a scratch. “How did you not get lost?” they want to know. Greg can’t understand what the fuss is about. “I had a compass,” he says. An epic Western—great soundtrack, too.
