Linnaeus: Systema Naturae, Regnum Animale (1735)

The Animal Kingdom is divided into six named Classes, each containing a number of Orders, which in term comprise a series of Genera and constituent Species. These are five of the standard seven categories of modern taxonomy, which includes Phyla and Families. Note the inclusion of sloths (Bradypus) among the human-like Anthrpomorpha, Dolphins (Didelphis) among Animals (Ferae), and the distinction of odd-toed from even-toed ungulates (Jumenta vs Pecora). Note also the inclusion of the Satyr, Phoenix, and Dragon, under the Paradoxa, a category that today we would call incertae sedis.
