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.
As for the compass usage in navigation, Shen Kua mentioned it in his bookâDream Pool Essaysâ in 1086. There were other recorded Chinese usage of the compass for navigation in 1124, 1126. However Needham thought the compass was first used for navigation in the period from 850â1050. This is about a century before the compass was mentioned by Alexander Neckam in âDe Naturis Rerumâ in 1190. The compass did not reach Europe by way of the Arabs.
