A remarkable astrolabe from Al-Andalus, hitherto unknown and unpublished, is preserved in the Fondazione Museo Miniscalchi-Erizzo in Verona. It is datable to the eleventh century and features added Hebrew and Latin inscriptions.
"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."
