Arabus et Latinus

An International Catalogue of Mediaeval Scientific Manuscripts

        There are an estimated 30,000 to 35,000 mediaeval western "scientific" manuscripts scattered throughout the world. Many attempts have been made to catalogue them, from the early seventeenth century hand-written catalogues to the present-day printed catalogues. Even the most recent catalogues, however, cannot be updated or corrected at a reasonable cost. A computerized catalogue, on the other hand, can be updated, corrected, printed and made available to a wide range of users at any time and at low cost. 

Jordanus, an International Catalogue of Mediaeval Scientific Manuscriptsprovides information about mediaeval manuscripts written in Western Europe between 500 and 1500 A.D., which deals with mathematical sciences, i.e. arithmetic, algebra, geometry, trigonometry and mechanics. It is the result of research projects that were funded by the Volkswagen Foundation (1977-1985) and the Deutsche Forschungsgemeinschaft (1985-1989). The database was originally set up at the Lehrstuhl für Geschichte der Naturwissenschaften of the Ludwig-Maximilians-Universität in Munich by Prof. Dr. Warren Van Egmond and Prof. Dr. Andreas Kühne, and was later brought online by Dr. Gerhard Brey. It was provided an internet platform by King's College (London University) in cooperation with the Max Planck Institute for the History of Science in Berlin (Prof. Dr. Jürgen Renn). Jordanus is now available again on the server of the project Ptolemaeus Arabus et Latinus at the Bavarian Academy of Sciences in Munich. It was restored and reinstalled by Erwin Rauner
