The First compass was invented in China during the Han Dynasty between the 2nd century BC and 1st century AD, (we don’t know precisely when). At first, it was used for divination, fortune-telling and geomancy, for finding precious gems and in Feng Shui but in time people discovered that it can be used for navigation and orientation. People knew about magnetite even before then, but it took centuries for it to get at least some purpose.
