Vampires were undead beings and they were feared.
 Vampiric beings were rarely written about in Jewish literature; the 16th-century rabbi David ben Solomon ibn Abi Zimra (Radbaz) wrote of an uncharitable old woman whose body was unguarded and unburied for three days after she died and rose as a vampiric entity, killing hundreds of people
 They were described as having the bodies of crows or birds in general, and were later incorporated into Roman mythology as strix, a kind of nocturnal bird that fed on human flesh and blood
