The Age of Enlightenment filled the minds of men and women with wonder. It was a period of observation and discovery. Books furnished an avid public with new knowledge of the earth and the heavens. Information was presented in novel ways to captivate and educate the reader. These books inspire and delight. Geometric forms rise up out of the page, the moon spins on a turning wheel, and the invisible is rendered visible.

Joseph Breintnall’s leaf prints (Philadelphia, ca.1731- ca. 1742).
The vertical fold in the page is a clue as to how Brientnall achieved these detailed leaf impressions. He inked the leaf, folded the paper over the leaf and then used pressure to create the print. He made hundreds of leaf prints like this to collect botanical information. The tab on this page is evidence that this was bound in a book.
