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.
In Europe the compass is first mentioned in a French poem of 1190, but its application to navigation is mentioned only later. It was not until the fifteenth century that Europeans came to understand the principle of magnetic deviation about which Shen Kua had written some four hundred years earlier.ll of this was possible because we know how to make paper and to print with movable type  inventions which occurred in China. The world's first printed book, which is pictured below, was made in China, 1,074 years ago.
