The
vrykolakas (
Greek βρυκόλακας, pronounced ), variant
vorvolakas or
vourdoulakas, is a harmful
undead creature in
Greek folklore. It has similarities to many different
legendary creatures, but is generally equated with the
vampire of the folklore of the neighbouring Slavic countries. While the two are very similar, blood-drinking is only marginally associated with the
vrykolakas.
