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.
The truth is, there was no such thing as the compass in ancient times, and even after the compass was invented, it wasnât used all that much for marine navigation. Sailors in ancient times charted their course by the stars, and did not use a compass. No one knows where or when the first compass was invented. It may have been in China or in the Near East or in Italy. All we know is that the compass was first mentioned in the 12th century, and that it was first used on a European ship in 1345. These early compasses consisted of an iron needle attached to a piece of wood or cork that floated in a bowl of water. It wasnât until the 19th century that a really dependable compass was invented. But the compass is no longer used on ships, itâs been replaced by a much better device called the gyrocompass.
