French Emblems At Glasgow
"This website gives you access to all the French Emblem Books of the 16th century, along with their Latin versions when appropriate. While the seed of the emblem as a genre was sown in Germany in 1531, it flowered and developed in France during the 16th century, and it was from there that it spread throughout Europe."
There are hundreds of fantastic scenes on display in this collection. Here are the results I got when looking for dragons and monsters. Use the search bar on the top right to look up other images or browse the books directly from here.
