What is an Astrolabe? Think of the astrolabe as the “smartphone of the medieval world.” Long before GPS or Google Maps, scholars, sailors, and astronomers used this intricate instrument to read the stars, measure time, find direction, and even calculate prayer timings. It’s a flat, disk-shaped device, often made of brass, with moving parts that mimic the sky. A Brief History The astrolabe has roots going back to ancient Greece, but it truly flourished in the Islamic Golden Age. Muslim scholars r

Sailors used it to measure the height of the sun or stars above the horizon to determine latitude. 🔹 Octant Invented in the 1730s, the octant used mirrors to measure angles, allowing sailors to see the sun and horizon at the same time — far more accurate on a moving ship. �
