Evidence suggests that the magnetic compass was invented in China between 221 and 206 B.C. The earliest compasses were not used for navigation, but for fortune-telling. Chinese compasses became navigational orienteering devices between 1040 and 1044 A.D. and were used as maritime navigational devices by 1117 A.D.
Accounts of the history of the compass often points to 2nd century BC China as its place of origin. However there are researchers who say the Olmecs were using a compass around 1000 BC.n 1117 Zhu Yuâs book Pingzhou Table Talks came out.
