Konrad of Megenberg's "Book Of Nature"
Here are some of the stranger works found in Megenberg's Book of Nature from 1499. The book collected everything known from natural history at the time. And while much of what is illustrated appears fantastic, it was all based at least partly on fact or accepted truths from the time.
