This site contains two elements:
THE SAXL PROJECT provides illustrations and explanatory texts concerning more than 200 medieval and renaissance manuscripts dealing with the history of astronomy and astrology. There is also a working bibliography and sets of comparative images of the constellations. I have compiled the site in collaboration with the Warburg Institute, University of London and with the help of numerous colleagues. It is -- very much -- a work in progress, so all comments and corrections are welcome.
I have published extensively on subjects relating to art history, cultural history, the history of science and on scientific instruments. Several of these pieces originally appeared in conference proceedings or festschrifts, which are often difficult to find outside of major libraries. The site contains PDFs of all my scholarly publications to date.
