The Voynich Manuscript is one of the most obsessed-over historical enigmas. A medieval book dating from the late 15th or 16th century, its strange, flowing script has never been deciphered, its origins never determined. The 113 plant illustrations it contains seem to depict no flora found on Earth, and throughout its vellum pages are visuals of the cosmos, a small army of naked women cavorting through pools of water, and the arcane alphabet that has so frustrated linguists and cryptographers.

As the Yale Daily News reported last week and aficionados discovered online, new high-resolution scans of the manuscript were recently posted at Yale University’s Beinecke Rare Book and Manuscript Library site. Digital versions were previously available to the curious through the Beinecke, but the new scans are even sharper, and in sequential order you can closely examine each page. As the library explained to Hyperallergic, recent conservation work addressed folds and curls that had previously blocked some pages, and new scanning equipment made the color more accurate and didn’t require so much securing with straps on the delicate pages.
