|Pliny the Elder, H. Rackham, trans.|
|London: Harvard University Press, 1940; Series: Loeb Classical Library|
The complete Natural History in 10 volumes. Volume 3 is of the most interest for the study of the Bestiary, since it contains Pliny's books on zoology: Book 8 (mammals, snakes, lizards); Book 9 (aquatic species); Book 10 (birds); and Book 11 (insects). Natural History is a primary source for many of the Physiologus and Bestiary stories.
The Loeb volumes contain the Latin text with an English translation on the facing page.The first volume includes an introduction to Pliny and his works.
