Julio Samso is Professor in the Department of Arabic, University of Barcelona, Spain.
'Thanks to Variorum, the work of historians such as Julio Samso, who study mainly, but not exclusively, the history of Islamic exact sciences in the western part of the Islamic world and who usually publish in diversified journals and collected works scattered all over the world, can now be made more accessible between the covers of one book. This book in particular is an added blessing, for it not only brings together some of the more specialized articles of Professor Samso but also includes an updated bibliography in the form of additions and corrections, a detailed general index, and most importantly an index of sexagesimal parameters.' Journal for the History of Astronomy 'This interesting collection of articles is the second, and very welcome, volume of Samso's papers in the Variorum series.' Aestimatio 'This collection of papers by an eminent authority on the history of mathematics and astronomy in medieval Andalusia and the Maghreb will be a welcome addition to the library of all scholars with a serious interest in this area. ... Both Professor Samso and the publisher deserve our thanks for making this work available to scholars of medieval Islamic astronomy.' Journal of Islamic Studies
