Hartmann's Practika

A Manual for Making Sundials and Astrolabes with the Compass and Rule

Georg Hartmann (1489-1564) was one of the most renowned instrument makers in sixteenth century Nuremberg. Today his 300 page manuscript resides in the sterreichische

Nationalbibliothek along with two other manuscripts with related figures and prints in two other libraries. Now finally, after almost 500 years, his work is complete. It is, at last, a book!
