Islamic Astrolabe Tradition

Timeline

1. c. 800–900Baghdad · IraqThe Abbasid House of Wisdom systematically translated Greek astronomical works such as those of Ptolemy; the astrolabe, as a core observation and computation tool, was incorporated into the Islamic astronomy curriculum, and scales began to be customized according to local latitudes.
2. c. 950–1100Isfahan · IranCraftsmen and scholars in Persia and al-Andalus improved astrolabe structures, developed variants such as the linear astrolabe, and formed diversified product lines serving scholars, navigators, and prayer-time computation, with markedly improved craftsmanship and scale precision.
3. c. 1390–1500Samarkand · UzbekistanThe Timurid dynasty and successor regimes continued to sponsor astronomical observation; portable precision instruments such as astrolabes and quadrants were used alongside large fixed observational equipment in court observatories and Islamic schools, and transmission to the Ottoman and Mughal worlds continued.
