By the early 17th century the Scientific Revolution was well under way. Philosophers and scientists were throwing off the yoke of ancient authority to peer at nature and the cosmos through microscopes and telescopes.

In October 1632, in the small town of Delft in the Dutch Republic, two geniuses were born who would bring about a seismic shift in the idea of what it meant to see the world. One was Johannes Vermeer, whose experiments with lenses and a camera obscura taught him how we see under different conditions of light and helped him create the most luminous works of art ever beheld. The other was Antoni van Leeuwenhoek, whose work with microscopes revealed a previously unimagined realm of minuscule creatures.

By intertwining the biographies of these two men, Laura Snyder tells the story of a historical moment in both art and science that revolutionized how we see the world today.
