From the epic poems of Homer to contemporary science fiction, from the Holy Scriptures to modern mythology and fairy tale, literature and art are full of illusory places we have at some time believed are real, and onto which we have projected our dreams, ideals and fears. Umberto Eco leads us on an illuminating journey through these legendary lands - Atlantis, Thule and Hyperborea, the Earth's interior and the Land of Cockaigne - and explores utopias and dystopias where our imagination can confront concepts that are too incredible, or too challenging, for our limited real world.
