Very very rare. Subtitle: A CRITICAL DESCRIPTION OF THE ASTROLABES, NOCTILABES AND QUADRANTS IN THE CARE OF THE UTRECHT UNIVERSITY MUSEUM. Tables, diagrams, descriptions, definitions, prints and history included, as well as specific astrolabes. About 1/3 of the book is a series of very clear and detailed photos of all kinds of these instruments. Great deal, recommended.
Rare. Softcover, 90 pages.
