The first proportional compasses were invented in the mid sixteenth century. Galileo invented a geometric and military compass in Padua in 1597. With his compass it was possible to make all sorts of arithmetical and geometrical calculations, from calculating interest to square and cube roots to drawing polygons and surveying.
The number zero was the first "invented" number.
Muslims use specialized compasses for locating the direction of Kabatullah (the Ka'aba in Mecca) at the time of offering Namaaz (Prayer/Supplication).

The first compass was invented around the year 1044. Modern liquid magnetic compasses stem from the mariners compass that was invented in Europe around 1190.
Ya Mum!
The compass was first used by Chinese and Mediterranean sailors in about the 1000's or so. The exact date when the compass was first invented is not known precisely. These first compasses were usually pieces of magnetic iron floated upon pieces of cork or straw in a bowl of water. With heavy iron and steel ships became precedent during the 1800's the use of lead compasses became pretty much obsolete, for this reason the gyrocompass was invented.
The plural possessive for compasses is compasses'.
Before compasses were invented, people used natural navigation methods such as observing the position of the sun, moon, and stars, as well as landmarks and natural signs like wind patterns and animal behavior to navigate and find directions.
There are two main types: Magnetic compasses and gyro compasses.
Before compasses were invented, navigators relied on observing the position of celestial bodies such as the sun, moon, and stars, as well as natural phenomena like winds, currents, and bird migrations. They used these natural cues to navigate their vessels across the oceans.
A magnetic compass was first used by the Chinese Han Dynasty.
It was invented by the Chinese people in the Qin dynasty (221-206 BC). They made these early compasses with a mineral that aligns itself the the earth's magnetic field called lodestone.
The possessive form of compass is compass's.
watches kind of like compasses!
