History of the Compass Timeline

Fourth-century Tamil nautical books mention a compass. Its early name, macchayantra, meaning “fish machine,” has been taken as evidence suggesting a Chinese origin or influence.

Alexander Neckam described a magnetized compass needle used by sailors in De utensilibus and De naturis rerum after returning to England from France. These texts document compass use in the English Channel and represent the earliest European evidence.

Around 1190, Western Europe received its first literary description of a compass. Neckam’s De naturis rerum explains how sailors touched a needle with a magnet and used its north-pointing orientation when sun and stars were obscured.

The earliest recorded reference to a compass in the Muslim world appears in the Persian talebook Jawami ul-Hikayat. It describes a compass used during navigation in the Red Sea or Persian Gulf.

Baylak al-Qibjāqī described a needle-and-bowl compass used during his voyage from Syria to Alexandria in 1242. His account was written in Cairo in 1282 and is the earliest Arabic description of this form of compass.

Dry compasses began appearing in medieval Europe around 1269. Their pivoted needles represented a significant mechanical development beyond the earlier floating magnetic needle in a bowl of water.

In Epistola de magnete, Petrus Peregrinus of Maricourt described both a floating compass for astronomical purposes and a dry compass for seafaring. His work is among the most important medieval European technical accounts of magnetism.

The Yemeni sultan and astronomer al-Malik al-Ashraf described the compass as a qibla indicator. He also explained its use for determining the meridian and the direction of Mecca.

Between 1295 and 1302, Flavio Gioja was traditionally credited with converting the floating needle into a compass with a round box and a 360-degree compass card attached to the magnetic element. This design gave the sailor’s compass its familiar form.

Dry compasses began appearing in the medieval Islamic world around 1300. Their use developed alongside magnetic needle-and-bowl instruments for navigation and determining the direction of Mecca.

An Arabic treatise by the Egyptian astronomer and muezzin Ibn Simʿūn describes a dry compass used as a qibla indicator. The instrument helped determine the direction toward Mecca.

The Syrian astronomer and timekeeper Ibn al-Shatir invented a timekeeping device incorporating a universal sundial and a magnetic compass. The instrument demonstrates the integration of magnetic direction-finding with astronomical timekeeping.

An Egyptian report from 1399 identifies two different kinds of magnetic compass. This record reflects the coexistence of multiple compass constructions in the medieval Islamic world.

China adopted the European compass-card in a box frame with a dry pivot needle after the design was transmitted through Japanese pirates who had learned it from Europeans. The older Chinese suspended dry compass nevertheless remained in use into the 18th century.

In 12th-century Denmark, about one quarter of 570 Romanesque churches were rotated several degrees clockwise from true east–west. Their orientation corresponds to the period’s magnetic declination and suggests fairly common compass use.

In Massa, Tuscany, floating magnetic needles were used underground for tunneling and for defining mining claims. This was an early application of the compass as a subterranean direction finder.

Traffic between the Mediterranean and northern Europe increased in the closing decades of the 13th century. The compass may have made crossing the Bay of Biscay safer and helped support direct commercial voyages into the English Channel.

By around 1290, Mediterranean sailing seasons could begin in late January or February and continue until December. Compass-assisted navigation contributed to the gradual increase in shipping during periods formerly avoided because of unreliable skies.

In the 15th century, the navigator Ibn Majid described aligning the compass with the pole star. His account indicates awareness that magnetic north and true north could differ, an effect now called magnetic declination.

A German miner, Rülein von Calw, published the first detailed treatise devoted to the underground use of compasses. His work formalized compass-based mining surveying.

Flavio Gioja, traditionally described as an Italian pilot from Amalfi, is credited with perfecting the sailor’s compass by suspending its needle over a compass card. Later evidence shows that related pivoting designs predated him.

A commentary on Dante’s Divine Comedy from 1380 describes a compass with a needle attached to a rotating card. An earlier reference to a portable compass in a box, dated 1318, further supports the early European use of dry compasses.

William Gilbert’s publication of De Magnete in 1600 helped move the explanation of magnetic remanence and induction away from supernatural and occult interpretations toward experimental natural philosophy.

Sir Edmond Halley introduced a rudimentary working liquid compass at a meeting of the Royal Society in 1690. The design anticipated later efforts to damp needle movement with fluid.

Dry compasses were already in common use by the early 18th century and were described in the 1728 Cyclopaedia. Their continued prevalence preceded the broad adoption of liquid-filled instruments.

Englishman Francis Crow patented the first liquid mariner’s compass considered practicable for limited use. The fluid helped damp the motion of the compass card in marine conditions.

Liquid-damped marine compasses were used occasionally by the Royal Navy from the 1830s through the 1860s. The standard Admiralty compass, however, remained a dry-mounted design during this period.

French physicist Léon Foucault made the first gyroscope for scientific use in 1852. His work established the rotating-instrument principle that later enabled gyrocompasses independent of magnetic direction.

Marinus Gerardus van den Bos patented a gyrocompass in the Netherlands in 1885. Small electric motors made continuous spinning possible and enabled a nonmagnetic approach to finding direction.

A 1885 patent introduced a hand compass with a viewing prism and lens. The arrangement allowed users to sight geographical landmarks accurately while reading the heading, creating the prismatic compass.

The Bézard compass was first patented in 1902. It consisted of a field compass with a mirror mounted above it, allowing users to observe the direction while sighting.

German inventor Hermann Anschütz-Kaempfe built the first practical gyrocompass in 1906. His achievement transformed the gyroscopic principle into a usable navigational instrument.

Although liquid compasses had been tested earlier, they were not introduced generally into the Royal Navy until 1908. This marked a major institutional shift from dry-mount marine compasses.

Captain F. O. Creagh-Osborne introduced an aircraft compass using alcohol and distilled water to damp the compass card. The design addressed the motion and vibration encountered in aviation.

Creagh-Osborne adapted his aircraft-compass technology into a smaller pocket model for artillery and infantry officers. He received a patent for the individual-use design in 1915.

In December 1931, the newly founded Swedish Silva Company introduced its first baseplate or bearing compass. A liquid-filled capsule damped the swing of the magnetized needle.

In December 1932, Gunnar Tillander and the three Kjellström brothers formed the Silva Company. It manufactured and sold Silva orienteering compasses to Swedish orienteers, outdoorsmen, and military officers.

Silva’s early-1930s designs popularized the liquid-filled capsule for field navigation. This construction improved readability and stability compared with earlier floating or dry-mounted arrangements.

Surveyor Tuomas Vohlonen applied for a patent for a lightweight celluloid compass housing filled and sealed with petroleum distillate. The liquid damped the needle and protected it from shock and excessive motion.

Suunto introduced the Model M-311 in a wrist-mounted form in 1936. Vohlonen’s capsule design led directly to the lightweight liquid-filled field compasses used today.

An automatic sun compass developed by Lieutenant Colonel James Allason was adopted by the British Army in India in 1938. It was intended for tanks and armored vehicles, where magnetic fields could distort standard prismatic compasses.
