De Solaribus Horologiis & Quandrantibus
(On Solar Clocks & Quadrants)
Oronce Fine, French (1494-1555)
Parisiis: Apud Gulielmum Cauellat, 1560
This book focuses on the 16th-century instruments of time-keeping. In his discussion of sundials, astrolabes, and quadrants, Fine incorporates a large amount of line diagrams, illustrations of instruments, and mythical imagery. This combination of image makes the text more educational and visually interesting for the everyday reader. The end of the book even includes a ‘practice quadrant’ that readers can cut out and assemble to gain familiarity with the instrument and practice the concepts in the book.
