Welcome to a 3D virtual gallery you can walk through in your browser, tracing how a magnetized needle changed the shape of the known world.
The magnetic compass was first built in Han dynasty China, not to navigate but to practice divination. A lodestone ladle on a bronze plate, spinning to point south. It took a thousand years before anyone thought to carry it to sea. By 1088, Song dynasty sailors were using iron needles struck with lodestone to cross open water. Within two centuries, that small pivot had opened every ocean on Earth.
The compass joined ancient methods of navigation based on sightings of the sun and stars. Its use for navigation in the Indian Ocean was first mentioned in 1232. In Europe, the first recorded use was around 1190. Arab traders adopted it. Portuguese and Spanish voyages that defined the Age of Discovery depended on it, opening maritime routes to India by 1498 and crossing the Atlantic from 1492.
A compass points to magnetic north, not true north. The angle between them, called magnetic declination, shifts with location and over time. Near the magnetic poles the compass becomes useless, drifting without settling. Iron on a ship's hull, electrical engines, and ore deposits all distort the reading. Mariners must add or subtract local variation and deviation to convert a compass bearing into a true one.
Around the 2nd century BC, Chinese geomancers shaped lodestone into a south-pointing spoon placed on a smooth bronze plate for divination. By 1088, Shen Kuo described iron needles magnetized by striking them with lodestone. Shen Kuo was also the first to accurately describe magnetic declination, the difference between true north and magnetic north. Dry compasses appeared around 1300 in Medieval Europe.
