The above images are drawn from Early European Books Online, a ProQuest database that features digitized European books printed before 1700. Many of the texts are medical, alchemical or pharmacological and feature all kinds of recipes (including culinary). Often, since the digitized images were scanned from the original books, marginalia and annotations are present.
