Lykanthropos

Early sources for belief in this ability or affliction, called lycanthropy /laɪˈkænθrəpi/, are Petronius (27–66) and Gervase of Tilbury (1150–1228). The term lycanthropy, referring both to the ability to transform oneself into a wolf and to the act of so doing, comes from Ancient Greek λυκάνθρωπος lukánthropos (from λύκος lúkos "wolf" and ἄνθρωπος, ánthrōpos "human".[3] The word does occur in ancient Greek sources, but only in Late Antiquity, only rarely, and only in the context of clinical lycanthropy described by Galen, where the patient had the ravenous appetite and other qualities of a wolf; the Greek word attains some currency only in Byzantine Greek, featuring in the 10th-century encyclopedia Suda.[4] Use of the Greek-derived lycanthropy in English occurs in learned writing beginning in the later 16th century (first recorded 1584 in The Discoverie of Witchcraft by Reginald Scot, who argued against the reality of werewolves; "Lycanthropia is a disease, and not a transformation." v. i. 92), at first explicitly for clinical lycanthropy, i.e. the type of insanity where the patient imagines to have transformed into a wolf, and not in reference to supposedly real shape-shifting. Use of lycanthropy for supposed shape-shifting is much later, introduced ca. 1830.

A few references to men changing into wolves are found in Ancient Greek literature and mythology. Herodotus, in his Histories,[7] wrote that the Neuri, a tribe he places to the north-east of Scythia, were all transformed into wolves once every year for several days, and then changed back to their human shape. In the second century BC, the Greek geographer Pausanias related the story of Lycaon, who was transformed into a wolf because he had ritually murdered a child. In accounts by the Bibliotheca (3.8.1) and Ovid (Metamorphoses I.219-239), Lycaon serves human flesh to Zeus, wanting to know if he is really a god. Lycaon's transformation, therefore, is punishment for a crime, considered variously as murder, cannibalism, and impiety. Ovid also relates stories of men who roamed the woods of Arcadia in the form of wolves.[8][9]

In addition to Ovid, other Roman writers also mentioned lycanthropy. Virgil wrote of human beings transforming into wolves.[10] Pliny the Elderrelates two tales of lycanthropy. Quoting Euanthes,[11][12] he mentions a man who hung his clothes on an ash tree and swam across an Arcadianlake, transforming him into a wolf. On the condition that he attack no human being for nine years, he would be free to swim back across the lake to resume human form. Pliny also quotes Agriopas regarding a tale of a man who was turned into a wolf after tasting the entrails of a human child, but was restored to human form 10 years later.

In the Latin work of prose, the Satyricon, written circa AD 60 by Gaius Petronius Arbiter, one of the characters, Niceros, tells a story at a banquet about a friend who turned into a wolf (chs. 61-62). He describes the incident as follows, "When I look for my buddy I see he'd stripped and piled his clothes by the roadside... He pees in a circle round his clothes and then, just like that, turns into a wolf!... after he turned into a wolf he started howling and then ran off into the woods."

Before the end of the 19th century, the Greeks believed that the corpses of werewolves, if not destroyed, would return to life in the form of wolves or hyenas which prowled battlefields, drinking the blood of dying soldiers. These may have been reports of vrykolakas. In the same vein, in some rural areas of Germany, Poland and Northern France, it was once believed that people who died in mortal sin came back to life as blood-drinking wolves. These undead werewolves would return to their human corpse form at daylight. They were dealt with by decapitation with a spade and exorcism by the parish priest. The head would then be thrown into a stream, where the weight of its sins was thought to weigh it down. Sometimes, the same methods used to dispose of ordinary vampires would be used.
