Ovid's witty and exuberant epic starts with the creation of the world and brings together a series of ingeniously linked Greek and Roman myths and legends in which men and women are transformed, often by love - into flowers, trees, stones and stars.

Throughout history, some books have changed the world. They have transformed the way we see ourselves - and each other. They have inspired debate, dissent, war and revolution.

They have enlightened, outraged, provoked and comforted. They have enriched lives - and destroyed them. Now Penguin brings you the works of the great thinkers, pioneers, radicals and visionaries whose ideas shook civilization, and helped make us who we are.
