Islamic Astrolabe

Timeline

1. 800–1000House of Wisdom, Baghdad · IraqBuilding on translations of Greek astronomical works, Islamic scholars improved astrolabe scales, projections, and zodiacal divisions, making them suitable for the Islamic calendar and determining the qibla; manuals on making and using astrolabe (such as the Ibrahim al-Fazari tradition) circulated among scholars.
2. 1000–1300Isfahan · IranPersian and Andalusian craftsmen cast astrolabes in fine brass, improving the precision of scales and star tables; the instruments served not only astronomers but also entered courts and mosques, used for determining prayer times and astrological consultations.
3. 1341–1350Damascus · SyriaIn the 1340s, Islamic astrolabes were still widely made and used in Mamluk Egypt and Syria; astronomers such as Ibn al-Shatir refined planetary models in Damascus, with the astrolabe serving as an observation and teaching tool alongside precise astronomical computation, and it also reached Christian Europe via Iberia.
4. 1200–1500Toledo · CastileThrough the Iberian translation movement and trade, Islamic astrolabe technology reached Latin European universities and navigators, spurring localized European astrolabe production and becoming a key medium linking the Islamic scientific revolution with modern astronomy.
