This book is an entertaining approach to what the people of the Golden Age thought about the natural and the supernatural. In its pages the boundaries between the possible and the impossible, the life and the hereafter are erased. The imagination can transform or build reality, and daily life spaces are invaded by elves, goblins, demons, and lost souls. In this book's pages, the reader will realize how some phenomena are perfectly described by the historians and the great writers of Spanish literature. These phenomena appear today in the mass media: sightings of strange lights, abductions, night visitors. Due to its excellent documentation obtained from literary and historical sources and because of the entertaining and efficient reconstruction of the stories that illustrate the pages of this work, this book is the most extensive introduction to how the natural world was conceived and the supernatural and its relationships, by men from the Golden Age.
