Ortus sanitatis, aka The Garden of Health (sometimes Hortus Sanitatis)is an early natural history encyclopedia, first published in Mainz in 1485. Our copy—the 1497, third edition—is not colored, sadly. But happily that means you can print the pages and color them yourself! The book has its fair share of whimsical woodblocks, including both real and mythical life forms, and was a guide to using natural materials for medicinal use.
