Images from Monstrorum historia cum Paralipomenis historiae omnium animalium by Ulissi Aldrovandi (Aldrovandus), 1642:
During nearly a year of confinement in Rome while fighting a heresy charge, Aldrovandi developed a strong interest in the natural world. He began to collect all manner of specimens which apparently came to constitute a formidable natural history museum for those that visited him.
He travelled quite a bit in his quest for specimens and recorded his observations in some 4000 manuscripts, a number of which were published during his lifetime. His writings include studies in ornithology, medicine, hydrology, zoology, botany and, as can be imagined from the embellished and fantastical images here, a paper on mythical creatures as well (among others).
