COMPASUL
This modern invention may have originally been created for spiritual purposes. Later it was adapted for navigational purposes. The earliest compasses were most likely invented by the Chinese, around 200 BC. Some were made of lodestone, which is a naturally-occurring form of the mineral magnetite. There is also evidence that other civilizations may have also used lodestone. At some point, possibly around 1050 CE, people began suspending the lodestones so they could move freely, and using them for navigation. A description of a magnetized needle and its use among sailors occurs in a European book written in 1190, so by that time, it is likely that the use of a needle as a compass was commonplace.
