This week we take a foray back into Slavic folklore, with a look at the female demonic figure known as the Strzyga (or Striga, or Strega). These are creatures with a gray or bluish appearance that feed on the flesh and blood of humans, and are connected to the Roman "Strix", a bird of ill omen usually associated with the owl. They have two souls, two hearts, and often two sets of teeth, and have characteristics in common with the vampire, though they are associated more with witchcraft. We discuss the origins of the Strzyga, including ideas about the dead and the underworld. We also look at similarities to Roman ancestral belief, as well as the associations of the Strix and the significance of having "two" beings within one.
