The Verona astrolabe was adapted, translated and corrected for centuries by Muslim, Jewish and Christian users in Spain, North Africa and Italy

Amazing stuff!

"The identification of an eleventh century Islamic astrolabe bearing both Arabic and Hebrew inscriptions makes it one of the oldest examples ever discovered and one of only a handful known in the world.

The astronomical instrument was adapted, translated and corrected for centuries by Muslim, Jewish and Christian users in Spain, North Africa and Italy. ...

“This isn’t just an incredibly rare object. It’s a powerful record of scientific exchange between Arabs, Jews and Christians over hundreds of years.” ..."

From the abstract:

"This article presents a hitherto unknown remarkable astrolabe from Al-Andalus which likely belonged to the collection of Ludovico Moscardo (1611–1681) assembled in Verona in the seventeenth century. The astrolabe is datable to the eleventh century and features added Hebrew and Latin inscriptions. It underwent many modifications, additions, and adaptations as it changed hands and owners over time thus becoming a palimpsest object. With its added translations from Arabic into Hebrew, the astrolabe closely recalls the recommendations prescribed by the Spanish Jewish polymath Abraham Ibn Ezra (1089–1167) in the earliest surviving treatise on the astrolabe in the Hebrew language written in 1146 precisely in Verona. The astrolabe—today preserved in the Fondazione Museo Miniscalchi-Erizzo—stands out as a testimony to the contacts and exchanges among Arabs, Jews and Europeans in the medieval and early modern periods."
