Astrolabe (back)

An astrolabe is an instrument used by early astronomers to measure the altitude of stars and planets and also as a navigational aid. This brass example was made in India in the 17th century, possibly by Diya ad-din, an instrument maker based in Lahore.

The back of the astrolabe includes a sine and cosine quadrant and a graph of the meridian altitude of the sun throughout the year for latitudes 18 and 20 degrees.

Astrolabe construction in the Middle East has a longer and more continuous history than in Europe. The earliest instruments which survive are from the 9th century and were made by Syro-Egyptian astrolabists working in Baghdad, Damascus and Cairo.
