The world’s first compass was made in China during the Qin Dynasty. It was made with lodestone – an iron oxide-based mineral that aligns itself in a north-south direction due to the Earth’s magnetic field – which was commonly used in Chinese geomancy and fortune-telling.
The use of a compass was recorded in several Chinese texts including a 4th century book entitled the Book of the Devil Valley Master, which describes its use in pathfinding. The first person officially recorded to have used the compass as a navigational aid was Chinese admiral Zheng He, who made eight sea voyages between 1405 and 1433.
