コンパスの誕生と歴史
The compass was invented in ancient China during the Han Dynasty (2nd century BC to 1st century AD). Initially, it was used for divination as a "south-pointing fish" made of magnetized material. By the Song Dynasty (960–1279 AD), it became a vital tool for navigation and military purposes. The compass reached Europe around the 12th century, significantly advancing maritime exploration. With the compass, sailors could determine directions without relying on landmarks or celestial bodies, paving the way for the Age of Discovery.
