Views of the Invisible

Tabula Anemographica seu Pyxis Nautica, Johannes Jansson, 1650

Jansson’s wind rose chart or anemograph, is the first plate of the first sea atlas published in the 17th century. While a beautiful view, it also served a very practical purpose of helping navigators understand the direction of winds and how they are named in different languages. 32 winds are named and six languages are used. Outside the circle are heads blowing the winds, with their physical characteristics representing the people of the regions where the winds originate. The invisible winds are made visible through these heads blowing them in the directions they take during the year.

Geological Chart, Levi Walter Yaggy, 1893

Yaggy's large geographical charts are among the most beautiful and impressive educational charts published in the 19th century. Using chromolithography, Yaggy created stunning colors and contrasts in his images of the world, its regions, and peoples. This Geological Chart was part of a set of ten charts that were used in schools to teach students geography. Geologic illustrations like this one attempt to show the invisible layers that exist beneath the surface of the earth. Yaggy’s drawings and colors dramatically illustrate geological concepts, making visible what cannot be directly seen.
