‘[This] is a heterogeneous collection, offering readers insight into specific medieval sundials and Renaissance astrolabes in addition to the astrolabes from medieval Europe advertized by the book title… [King] has given us a sample of his scholarship and methods of interrogating scientific instruments in this volume’ – Aestimatio 11 (2014)

'The articles in this book are illustrated with excellent photographs. The content of each one is completed with a comprehensive bibliography. I liked the book and I strongly recommend it. Its reading, though not easy, is indispensable to those who want to unravel the secrets of astronomical instruments. Professor King gives us a taste of how we can do so’ - Suhayl

'... le recueil montre a suffisance la nécessité de considérer les instruments astronomiques comme des sources a part entière, non seulement pour l’histoire des sciences et de la technique, mais encore pour l’histoire de l’art, l’épigraphie, la linguistique ou encore l’histoire culturelle, pour peu que l’on s’intéresse aux usages de la science et de la technique dans un milieu donné. Nul doute non plus que ce recueil ne serve a introduire les profanes dans un champ d’études fascinant qui réserve encore de nombreuses surprises’ - Francia-Recensio
