The compass opened the world to exploration and discovery. Invented in China thousands of years ago, it was primarily used by feng-shui priests, hired to advise on how and where to build. Today the compass still is a basic tool, a magnetized needle rotating on a vertical pin, pointing at the Earth’s magnetic North. 16th century sailors accustomed to following coastlines, could suddenly cross oceans. This is a replica small Georgian era combination sundial and compass with brass lid to protect the convex glass cover.
