Part Three: The Compass

The Compass

The compass was invented in China during the Han Dynasty soon after the 1st century BC. It originally was made of Iodestone, a naturally magnetized ore of iron that when suspended it would freely point the same direction, towards the magnetic poles.

The ability to know what direction you are going at anytime was what opened the age of exploration as seas and new land could be explored all year long, through fog and clouds. Thus allowing for the generation of maps, a crucial element that aided species development for thousands of years.
