Book, Oculus artificialis teledioptricus sive telescopium (The Eye Also of a Telescope or an Artificial Teledioptricus), 1702

This is a Book. It was printed by Johannis Ernesti Adelbulneri.

This object is not part of the Cooper Hewitt's permanent collection. It was able to spend time at the museum on loan from Smithsonian Libraries and Archives as part of Saturated: The Allure and Science of Color.

It is dated 1702. Its medium is letterpress and engraving on paper.

Predating Newton’s Opticks by two years, Johann Zahn’s system was one of the last extending from the classical tradition of color theory established by Aristotle. Zahn’s color diagram takes the shape of an equilateral triangle, with black and white at opposite ends of the base and yellow, red, and blue in between. Lines connect colors on the opposite sides of the triangle, creating diamonds of mixed colors.

It is credited Gift of Bern Dibner, Smithsonian Libraries, QC380 .Z19.
