4: BPE (Before Photography Era)

The invention of photography in the nineteenth century did not arise suddenly, nor did it emerge in isolation. It was the culmination of centuries of human effort to record, reproduce, and preserve the visible world. Long before light was captured on chemically treated plates, people were already seeking ways to make images endure—whether through prehistoric cave paintings that fixed memory in stone, Renaissance experiments with perspective and optics, or Enlightenment explorations into chemistry and projection devices.

Underlying all these efforts was a constant human impulse: the desire to capture time, to give permanence to what is fleeting. As Susan Sontag observed, “all photographs are memento mori,” reminders that images serve both as memory and as possession. That impulse predates the photograph itself, extending back to handprints on cave walls, to Egyptian tomb paintings meant to ensure immortality, and to medieval manuscripts preserving sacred stories. Each of these visual practices anticipated photography’s central role as a technology of remembrance.

The centuries before photography reveal a fascinating intersection of art, science, and culture. Philosophers like Mo Ti in China and Aristotle in Greece observed the pinhole projection of light, anticipating the optical principles of the camera obscura. Islamic scholars such as Alhazen advanced these ideas with experimentation, while European Renaissance artists like Brunelleschi, Alberti, and Leonardo da Vinci applied perspective and optics to transform visual representation. Later, inventors and showmen expanded these principles into devices of wonder—the magic lantern, phantasmagoria, and diorama—that trained audiences to trust projected images as both truthful and spectacular.

At the same time, chemists from the alchemist Albertus Magnus to Johann Heinrich Schulze uncovered the light-sensitivity of silver salts, laying the groundwork for photography’s chemical foundations. Writers and visionaries even imagined technologies that might allow nature to “draw itself,” foreshadowing what would soon become reality.

This chapter explores these pre-photographic traditions and technologies. By tracing the lineage of image-making—from pigments on cave walls to silver salts on glass—we see how photography arose not as a rupture with the past, but as the natural fulfillment of humanity’s enduring pursuit: to seize the fleeting, preserve the visible, and render memory permanent.
