From Tunis to Venice: Traces of Maghribī Astronomy and Geography in Manuscripts from Late Medieval Italy
Main Article Content
Abstract
This article discusses the shared content of three interrelated astronomical manuscripts from late medieval Italy, arguing that certain elements of this shared content trace their origins to Maghribī sources. This includes two tables of geographic coordinates with a pronounced focus on locations in North Africa as well as a gnomonic table for the latitude of Tunis. One of the coordinate tables is known to resemble an Arabic table in a zīj by Ibn al-Raqqām, who was active in Tunis, Béjaïa, and Granada in the period 1280–1315. It will be argued that a likely explanation of this knowledge transfer lies in the documented mercantile and diplomatic contacts between the Republic of Venice and Ḥafṣid Tunisia in the decades around 1300.
