The Witches or Witchcraft Through (the Ages is a 1922 Swedish-Danish documentary-style silent horror film written and directed by Benjamin Christensen. Based partly on Christensen's study of the Malleus Maleficarum, a 15th-century German guide for inquisitors, Häxan is a study of how superstition and the misunderstanding of diseases and mental illness could lead to the hysteria of the witch-hunts. The film was made as a documentary but contains dramatised sequences that are comparable to horror films.
