Monstrorum historia cum Paralipomenis historiae omnium animalium Bartholomaeus Ambrosinus… volumen composuit.

Aldrovandi assembled a large collection of specimens and notes on monsters which were published posthumously by Ambrosini, who added a number of personally observed cases. Those included the first detailed description and illustration of bladder exstrophy. Valuable case descriptions are mingled with fictitious ones, including specimens of false chimeras apparently created to please Aldrovandi’s patrons. Some of these can still be seen in the Aldrovandi collection at the University of Bologna. Digital facsimile from Google Books at this link.
