Monstrum septi ceps
Author: ALDROVANDI, Ulisse (1522-1605)
Aldrovandi was a prodigious writer of natural history. His book on monsters, profusely illustrated with marvellous woodcuts of monsters in the human, animal and vegetable realms, forms part of his great encyclopoedic work on natural history complete in thrirteen thick volumes, of which only four were published during his lifetime. His valuable teratological work is by far the most exahaustive treatise on monsters with descriptions and depictions of all kinds of monstrosities. Even if the woodcuts often are fanciful or largely inaccurate they exceeded a considerable influence and became the prototypes for succeeding illustrators of monsters.
