Two anonymous readers, working independently in different copies of the same Renaissance book, both decided it was secretly about alchemy. They were wrong about the book — but what they wrote in its margins is extraordinary. One followed the mercury-centered framework of Jean d'Espagnet, declaring the book's "true sense" to be the operations of "Master Mercury." The other followed the pseudo-Geber tradition, reading a human chess match as three rounds of chemical distillation. This site was built to show you what they saw.
The Hypnerotomachia Poliphili is a 500-page illustrated dream narrative published in Venice in 1499 — the most ambitious illustrated book of the fifteenth century.
