This is indeed an excellent book for those interested in history and biology. ~The Book of Beasts~ is a translation from Latin of a Twelfth century bestiary. It was written as a serious scientific study of zoology, despite giving equal precedence to dogs, horses, lions, dragons, and unicorns. This was the world of wildlife as the people of the 1100's saw it. It includes such beliefs as "when a lioness gives birth to her cubs, she brings them forth dead and lays them up lifeless for three days - until thier father, coming on the third day, breathes in thier faces, and makes them alive." (direct quote) The book also has an extensive appendix, detailing the history of the original manuscript of this bestiary, and information on ancient bestiaries as a whole. Further, the author tells us "No Latin prose bestiary has ever before been printed, even in Latin. This is the first and only English translation in print. . ." This is an invaluable reference to any students of historical sciences, especially biological/zoological sciences, or to any simply interested in the subjects. Very highly recommended.
