"Tales of the dead craving blood are ancient in nearly every culture around the world. Vampire-like spirits called the Lilu are mentioned in early Babylonian demonology, and the bloodsucking Akhkharu even earlier in the Sumerian mythology. These female demons were said to roam during the hours of darkness, hunting and killing newborn babies and pregnant women. One of these demons, named Lilitu, was later adapted into Jewish demonology as Lilith. Lilitu/Lilith is sometimes called the mother of all vampires.

The Ancient Egyptian goddess Sekhmet in one myth became full of blood lust after slaughtering humans and was only sated after drinking alcohol colored as blood.

In Homer's Odyssey, the shades that Odysseus meets on his journey to the underworld are lured to the blood of freshly sacrificed rams, a fact that Odysseus uses to his advantage to summon the shade of Tiresias. Roman tales describe the strix, a nocturnal bird that fed on human flesh and blood. The Roman strix is the source of the Romanian vampire, the Strigoi and the Albanian Shtriga, which also show Slavic influence.

In early Slavic folklore, a vampire drank blood, was afraid of (but could not be killed by) silver and could be destroyed by cutting off its head and putting it between the corpse's legs or by putting a wooden stake into its heart.

Medieval historians and chroniclers Walter Map and William of Newburgh recorded the earliest English stories of vampires in the 12th century.

Many vampire legends also bear similarities to legends regarding succubi or incubi."
