There are several vampiric entities that are said to exist. The most well known is Homo nosferapoda admordens, the haematophagic subspecies of Homo nosferapoda "night-walkers". Legends about these creatures first sprang up in Eastern Europe in the dark ages. Modern vampire myth became popularized in around the 17th century A.D. However, the earliest records of traditional vampirism date back to Ancient Egypt. Well into Babylonia and Ancient Greece there persists legends about bloodsucking entities vaguely resembling humans. Creatures that seem to take on a corporeal demonic form, contrary to the Romanian belief of vampires being the reanimated corpses of human beings.
