One of the most popular and widely read books of the Middle Ages, Physiologus contains allegories of beasts, stones, and trees both real and imaginary, infused by their anonymous author with the spirit of Christian moral and mystical teaching. Accompanied by an introduction that explains the origins, history, and literary value of this curious text, this volume also reproduces twenty woodcuts from the 1587 version. Originally composed in the fourth century in Greek, and translated into dozens of versions through the centuries, Physiologus will delight readers with its ancient tales of ant-lions, centaurs, and hedgehogs—and their allegorical significance.
