ancient chinese compass (11th century)

The creation of a little device in Ancient China over two thousand years ago would change the world forever. Before everyone had a GPS, the only way to get around was with a compass and a map. The first versions of compasses consisted of naturally magnetized pieces of magnetite called lodestone.

Compasses were created during the Han Dynasty in 200 BC, allowing humans to explore the world and discover new parts. However, that wasn’t the initial purpose. Instead, the Han Dynasty used it for spiritual reasons.

Also known as the South pointing fish, the Song Dynasty began using it for navigation during the 11th century. Later, it became a crucial device in human history that let explorers discover a whole new world.
