In the 10th and 11th centuries/16th and 17th centuries CE, Lahore was a center of the Islamic exact sciences, including mathematics, astronomy and metallurgy.  More than 100 astrolabes and other scientific instruments made by a Lahori family of instrument makers, are still extant today, scattered in museums and private collections all around the world. Using advanced metallurgic techniques,  the astrolabe makers to make thin plates, which were engraved with mathematical precision. The Lahori artistic workmanship was a high point in the entire Islamic tradition. We will show examples of the instruments, with photos of the instruments, and discuss the historic workshops on these instruments which we held in Lahore in 2018. Finally we will analyze the innovations made in Lahore and the scientific knowledge that was available in Lahore in those times.
