Mummy films are unique among classic monster movies in that they're neither primarily based upon myths or literature. Only Isaac Henderson's 1902 play, The Mummy and the Hummingbird and Bram Stoker's 1903 novel, Jewel of the Seven Stars, have inspired cinematic adaptations (the latter spawning four to date) with its subject of an archaeologist attempting to revive a mummy. There were a few examples of the mummy in literature, as with Edgar Allan Poe's "Some Words with a Mummy," Théophile Gautier's The Romance of a Mummy, Ambrose Pratt's The Living Mummy, Louisa May Alcott's "Lost in a Pyramid or, The Mummy’s Curse" and Sir Arthur Conan Doyle's "Lot No. 249" and "The Ring of Thoth" all deal with mummies, albeit not always in a horror setting, and have never even loosely been adapted into film.
The rise of mummy films seem to be directly related to a then-widespread interest in archaeology and, more specifically, an enduring western vogue for Orientalism and fascination with the Near East. Several major discoveries in the field of Egyptology occurred in the 20th century and helped renew and increase interest in one the the planet's oldest, most complex and enduring civilizations. Yet fascination with Egyptian mummies, with their tantalizing ties to the ancient past, never really translated into a healthy monster subgenre, only sporadically rising to the level of more continually popular monsters like vampires and ghosts.
