Origin of the 'vampires have no reflection' myth
Depending on what stories you read or movies you watch, vampires will and won't have reflections.
But what is the earliest reference to this particular myth and do we know it's origin?
One explanation I read was that the mirror image meant the vampire's soul; the vampire had no soul, hence no mirror image.
@VixenPopuli I'm more interested in the myth's earliest use / origin than a description of it.
This is a duplicate of http://scifi.stackexchange.com/q/38466/4918 "What is the origin of Stoker's idea that vampires' reflections cannot be seen?"
It's a relatively new addition to the vampire mythos. Attributed to Bram Stoker's Dracula.
Despite its important contributions to vampire fiction, several popular traits of fictional vampires are absent. Count Dracula is killed by a bowie knife, not a wooden stake. The destruction of the vampire Lucy is a three-part process (staking, decapitation, and garlic in the mouth), not the simple stake-only procedure often found in later vampire stories. Dracula has the ability to travel as a mist and to scale the external walls of his castle. One very famous trait Stoker added is the inability to be seen in mirrors, which is not something found in traditional Eastern European folklore.
J Gordon Melton's "The Vampire Book: The Encyclopedia of the Undead" says likewise (I wasn't *quite* convinced by that source, personally).
