Reviews

’... a welcome addition to the Variorum series and a most useful work for historians of medieval science.’ Aestimatio ’This book offers a splendid collection of articles on the transmission of Mediaeval science. It explores in depth the interesting subject of the exchange of knowledge between the Arab culture and Mediaeval Europe via Jewish intermediaries.’ Metascience ’Les services que rendent les éditions Ashgate à travers leur collection Variorum n'ont plus besoin d'être soulignés, et le volume qui réunit les articles de J.L. Mancha en fournit une nouvelle preuve: trouver regroupés sous un format commode et maniable les articles qu'un même auteur a consacrés à des questions voisines représente pour les amateurs une merveilleuse opportunité, d'autant que cet auteur a été prié de conforter l'unité thématique de son volume en le dotant d'un bref avant-propos de présentation et d'un index collectif.’ Archives Internationales d'Histoire des Sciences
