1534 1ed Apian Instrumentum Astronomy Mathematics Alchemy Durer ART Trigonometry

Peter Apian was a 16th-century humanist who is remembered for his studies in astronomy and mathematics. One of his best known works was his 1534 mathematics treatise 'Instrumentum Primi Mobilis'. This book was Apian's studies in trigonometry, and, according to Tomash & Williams,

"Apian published a table of sines that, for the first time, was based on a circle with a radius of a power of ten, in this case one hundred thousand. The values of the functions were thus decimal and were easily adapted to any situation in which the defining circle was a decimal power."

This 1534 first edition is exceedingly rare and valuable. It contains the expected sine charts as well as numerous woodcut illustrations depicting protractor and arc readings. Note that this incredible work includes the original title page, which features a woodcut after Albrecht Durer.
