Tracking the sea beasties

Modern maps rarely include wondrous sea monsters in their depictions of bodies of water. Author Chet Van Duzer laments this fact in his new book Sea Monsters on Medieval and Renaissance Maps. Tanya Lewis of LiveScience has a review.

"The creatures look purely fantastic. They all look like they were just made up," Van Duzer, a map historian at the Library of Congress, said in a talk about his book. "But, in fact, a lot of them come from what were considered, at the time, scientific sources." The author looks at the history of sea creatures from Roman times through the Middle Ages and Renaissance.
