- An astrolabe is a very ancient astronomical computer for solving problems relating to time (what time is it ?) and the position of the Sun and stars in the sky.
Astrolabes are used to show how the sky looks at a specific place (latitude) at a given time.
This is done by drawing the sky on the face of the astrolabe.
To use an astrolabe, you adjust the moveable components to a specific date and time. Once set, much of the sky, both visible and invisible, is represented on the face of the instrument.
Typical uses of the astrolabe include finding the time during the day or night, finding the time of a celestial event such as sunrise or sunset and as a handy reference of celestial positions.
The history of the astrolabe begins more than two thousand years ago.
The principles of the astrolabe projection (stereographic projection) were known before 150 B.C., and true astrolabes were made before A.D. 400.
The astrolabe was highly developed in the Islamic world by 800 and was introduced to Europe from Islamic Spain (al-Andalus) in the early 12th century.
It was the most popular astronomical instrument until about 1650, when it was replaced by more specialized and accurate instruments.
