ANTIQUE SEXTANT
Welcome to our selection of antique sextants.
The antique sextant is a very desirable maritime navigational instrument, they are a symbol of seafarers who have navigated the worlds oceans by using only the Sun, stars and Moon for fixing a position. The primary use of a sextant is to determine the angle between an astronomical object and the horizon for the purposes of celestial navigation. The angle and time can be used to calculate a position line on a nautical chart. A common use of the sextant includes sighting the sun at solar noon to determine latitude.
The Sextant was invented by Admiral John Campbell in 1757 after he discovered that the Octant was unable to measure angles large enough for Lunar distances ( Distance between Moon, Sun or Stars ) so he increased the 90 degree angle of the Octant to 120 degrees which formed the Sextant. He then engaged the nautical instrument maker John Bird to construct the first Sextant in 1759.
The Sextant gets its name from the Latin word for 'a sixth' because it is a sixth of a circle (60 degrees) and can measures angles of up to 120 degrees.
