We know all kinds of monsters. Vampires who suck human blood, werewolves who harass tourists in London or Paris, zombies who long to feast on our brains, or Godzilla, who is famous in and outside of Japan for destroying whole cities at once. Regardless of their monstrosity, all of these creatures are figments of the human mind and as real as they may seem, monsters are and always have been constructed by human beings. In other words, they are imagined. How they are imagined, however, depends on many different aspects and changes throughout history. The present volume provides an insight into the construction of monstrosity in different kinds of media, including literature, film, and TV series. It will show how and by whom monsters are really created, how time changes the perception of monsters and what characterizes specific monstrosities in their specific historical contexts. The book will provide valuable insights for scholars in different fields, whose interest focuses on either media studies or history.
