Undead in the context of "Barbara Radziwiłł"

A vampire is a mythical creature that subsists by feeding on the vital essence (generally in the form of blood) of the living. In European folklore, vampires are undead humanoid creatures that often visited loved ones and caused mischief or deaths in the neighbourhoods which they inhabited while they were alive. They wore shrouds and were often described as bloated and of ruddy or dark countenance, markedly different from today's gaunt, pale vampire which dates from the early 19th century.

Vampiric entities have been recorded in cultures around the world, but the term vampire was first popularized in Western Europe following reports of an 18th-century mass hysteria drawing on a pre-existing folk belief in Southeastern and Eastern Europe. This delusion led, in certain cases, not only to individuals being accused of vampirism, but also to the corpses of such suspected vampires being pierced with stakes.Local variants in Southeastern Europe were also known by different names, such as shtriga in Albania, vrykolakas in Greece and strigoi in Romania, cognate with Italian strega, meaning 'witch'.

A zombie (Haitian French: zombi; Haitian Creole: zonbi; Kikongo: zumbi) is a mythological undead corporeal revenant created through the reanimation of a corpse. In modern popular culture, zombies appear in horror genre works. The term comes from Haitian folklore, in which a zombie is a dead body reanimated through various methods, most commonly magical practices in religions like Vodou. Modern media depictions of the reanimation of the dead often do not involve magic but rather science fictional methods such as fungi, radiation, gases, diseases, plants, bacteria, viruses, etc.

The English word zombie was first recorded in the 18th century; dictionaries trace its origins to Bantu languages, such as Kimbundu nzumbi 'ghost, spirit'. One of the first books to expose Western culture to the concept of the voodoo zombie was W. B. Seabrook's The Magic Island (1929), the account of a narrator who encounters voodoo cults in Haiti and their resurrected thralls.

In fantasy fiction, a lich (/lɪtʃ/) is a type of undead creature with magical powers.

Various works of fantasy fiction, such as Clark Ashton Smith's "The Empire of the Necromancers" (1932), had used lich as a general term for any corpse, animate or inanimate, before the term's specific use in fantasy role-playing games. The more recent use of the term lich for a specific type of undead creature originates from the 1976 Dungeons & Dragons role-playing game booklet Greyhawk, written by Gary Gygax and Rob Kuntz.

A vrykolakas (Greek: βρυκόλακας or βρικόλακας, pronounced [vriˈkolakas]), is a harmful undead creature in Greek folklore. Similar terms such as vourkolakas (βουρκόλακας), vourvoulakas (βουρβούλακας), vorvolakas (βορβόλακας), vourvolakas (βουρβόλακας), vourdoulakas (βουρδούλακας) were also used for the creature.

It shares similarities with numerous other legendary creatures, but is generally equated with the vampire of the folklore of the neighbouring Slavic countries. While the two are very similar, a vrykolakas eats flesh, particularly livers, rather than drinking blood, which combined with other factors such as its appearance bring it more in line with the modern concept of a zombie or ghoul.
