In the winter of 2019, I found a Blaeu atlas in the basement of the Bodleian Library, its vellum pages still supple after three and a half centuries. The Pacific Ocean was mostly empty — a vast field of cream-colored parchment where a Dutch engraver had chosen silence over speculation. There were no depth soundings, no imagined continents, only a single sea monster curling near the equator and the faintest suggestion of trade winds rendered in hairline copperplate. I turned the page expecting the familiar outlines of modern cartography and instead found an honest admission: here be nothing we yet know.
The Virtue of the Unknown
We have lost something essential in our age of complete cartographic coverage. Every square metre of Earth has been photographed from orbit, measured by laser altimetry, and rendered in precise digital tiles that load in milliseconds. The blank spaces are gone, and with them a particular kind of honesty — the admission that knowledge has edges, that the world contains territories we have not yet earned the right to name.
