Gello
Encyclopedia
In the myth and folklore
of the Near East
and Europe
, Gello (also Gyllou, Gylou, Gillo, etc.) is one of the many names for a female demon
or revenant who threatens the reproductive cycle
by causing infertility
, spontaneous abortion
, and infant mortality
.
By the Byzantine era
, the gello had become a type of demonic possession
rather than an individual being. Women might be tried for being gelloudes or subjected to exorcism
.
inscriptional
evidence of a child-snatching demon appears on a silver lamella (metal-leaf sheet) from Palestine
and two incantation bowls dating to the 5th or 6th century; on these she is called Sideros (Greek for iron
, a traditional protection for women during childbirth). Under various names, she continues to appear in medieval Christian manuscript
s written in Greek
, Coptic
, Ethiopian
, Armenian
, Romanian
, Slavonic
, Syriac
, Arabic
, and Hebrew
. In literary texts and on amulet
s, the demon's adversaries are Solomon, saint
s, or angel
s.
Knowledge of a demon's name was required to control or compel it; a demon could act under an alias. Redundant naming is characteristic of magic charms, "stressing," as A.A. Barb noted in his classic essay "Antaura," "the well-known magic rule that the omission of a single one can give the demons a loophole through which they can work their harm."
In one Greek tale set in the time of “Trajan
the King,” the demon under torture reveals her “twelve and a half names”:
Elsewhere, the twelve-and-a-half names are given as Gylo, Morrha, Byzo
, Marmaro, Petasia, Pelagia, Bordona, Apleto, Chomodracaena, Anabardalaea, Psychoanaspastria, Paedopniktria, and Strigla. Although magic words (voces magicae) have often been corrupted in transmission
or deliberately exoticized, several of these names suggest recognizable Greek elements and can be deciphered as functional epithets: Petasia, "she who strikes"; Apleto, "boundless, limitless"; Paedopniktria, "child suffocator." Byzo is a form of Abyzou
, abyssos, "the Deep," to which Pelagia ("she of the sea") is equivalent.
Gello is named also in works by the polymaths John of Damascus
(7th–8th century) and Michael Psellos
(11th century), the latter of whom notes that he has found her only in "an apocrypha
l Hebrew book" ascribed to Solomon and not in his usual sources for demonic names in antiquity. Psellos was one of the earliest scholars to identify Gello with the Hebrew Lilith
, and says that these demons "suck blood and devour all the vital fluids which are in the little infant." The 17th-century Greek Catholic
scholar Leo Allatios
, however, criticizes Psellos and insists that the gello, Lilith and other demonic creatures should be regarded as separate and unrelated.
derived Gello from the Near Eastern demon Gallu
. M.L. West
also pointed to the Babylonian–Assyrian gallû, a word perhaps related to "ghoul," as a demonic revenant who brings sickness and death.
Because etymology in antiquity was interpretive and phonic
, and not based on scientific linguistics
, the Greeks themselves might have heard the root gel-, "grin, laugh," in the sense of mocking or grimacing, like the expression often found on the face of the Gorgon
, to which Barb linked the reproductive demons in origin. Such demons are often associated with or said to come from the sea, and demonologies identify Gyllou with Abyzou
, whose name is related to abyssos, the abyss or "deep."
(aition). The fears she personifies thus associate her with the Mormo
and Lamia
, whose narratives also show them to have suffered the fate that they in turn inflict on other women. Mormo, driven to insanity, killed and ate her own children; Lamia was the lover of Zeus
and bore him many children, but Hera
in her envy
killed each as it was born.
Gello was once a young woman who died a virgin. The Christian-era lexicographer
Hesychius
said that she was a ghost (eidolon) who attacked both virgins and newborn babies. The earliest mention of this demonic creature by her Greek name occurs in a fragment of Sappho
of Lesbos
, in which Gello is said to be "fond of children." The fragment is preserved by the 2nd-century compiler Zenobius
, who offers a psychological explanation:
Magic texts and amulets attest by name to the prevalence of a belief in reproductive demons in the Greco-Roman world
. During the Byzantine period, textual evidence of the child-harming demon is most often found in exorcism
s or demonologies
. Historian of ancient religion Sarah Iles Johnston suggests that this belief is expressed more commonly in earlier literature than has been noticed. The Homer
ic epics allude to the unmarried dead, who are excluded from the Underworld
and might harm the living. In the Homeric Hymn to Demeter
, Demeter
in her role as a kourotrophic ("youth-nurturing") goddess promises to protect her hosts' infant from demonic attack in language that recalls known magical incantations. Centuries later, in Augustan Rome
, Ovid
describes the practice of protecting doorways with buckthorn
after the birth of a child to ward off striges
, winged female demons who were thought to suck the blood of newborns. One of the twelve-and-a-half names of Gylo (see above) is Strigla, a form of the word strix as a kind of witch.
Michael Psellos says that Gello also killed pregnant women and their fetus
es. Thus Gello in general blocked the cycle of reproduction. The patriarch
John of Damascus, in the treatise Peri strygnôn ("Regarding striges
"), records a belief among the "common people," still current in his day, that ghosts called gelloudes or striges flew nocturnally, slipped into houses even when the windows and doors were barred, and strangled sleeping infants. John's use of the plural shows that Gello has become a type, rather than an individual revenant. The 14th-century Greek ecclesiastical historian
Nikephoros Kallistos Xanthopoulos
said gelloudes "bring the infant from the bedroom, as if about to devour him." Leo Allatios explicitly cross-identifies striges and gelloudes, recasting the demonic or revenant gello of Eastern tradition as the witch of Western Europe, who is often marginalized by age and poverty. The transformation of the gello from the ancient "virginal reproductive demon" to an envious crone
occurs in the Christian era; what the virgin and crone share is their exclusion from the reproductive cycle, and their envy of fertility. The Greek folk belief
continued into the modern era.
Although reports of Gello's behavior are consistent, her nature is less determinate. She is regarded as a demon in exorcisms and commanded as an "unclean spirit
" (akatharton pneuma
). But her aition as a human being would make a ghost of her, as did her gender
ed nature, since demons, like angels, were officially sexless in the theology of the Church
. Johnston prefers to use the Greek word aôrôs, "untimely dead," for this form of transgressive or liminal
soul or entity, finding the usual phrase "child-killing demon" to be misleading.
magico-medical compilation Cyranides
provides defensive spells against the "frightful woman" (horrida mulier) who attacks babies. The eagle-stone or aetites
is to be worn as an amulet
to prevent miscarriage
, to assure timely and complication-free delivery
, and to relieve delirium
and night terror
s associated with Gello and other revenants. A cross
or image of Christ
might be placed by a child's bed to ward off Gello or demons in general; burning lamps
to illuminate sacred images and incense
were also used in the bedroom. The practice of baptizing
infants was thought to offer protection against demon-snatching, and specifically against the gello, according to Leo Allatios
. Allatios also records, but does not condone, the hanging of red coral
or a head of garlic on the infant's cot, along with other remedies he finds too unspeakable to name.
by disguising herself as a fly on the saint's horse, since only Sisinnius could pass through the gate.
There is an Ethiopian tradition in which the sister of Sisinnius was possessed by a demon and killed newborns. When Sisinnius became a Christian
, he murdered her. In a Byzantine version, Sisinnius defends his sister Melitene's children from the demon Gyllou. A sample narrative of Melitene's travails against the gelu may be found online.
A 15th-century manuscript describes an encounter between the archangel Michael
and Gylou:
Although the name Gylou is not found on any surviving amulets, Michael is the adversary Gylou encounters most often in medieval Byzantine texts.
The protections against Gellou, as an embodiment of envy, resemble those against the evil eye
. One exorcism text dating from around the turn of the 19th–20th century gives Baskania as a name for the gello as well as for the evil eye.
in his work De Graecorum hodie quorundam opinionibus ("On the beliefs of the Greeks today"). Textual sources he collected on the Gello included Sappho's poem, the Suda
, exorcisms, a church history, the Life of Patriarch Tarasios of Constantinople
written by Ignatius the Deacon, and proverb
s. Allatios's purpose was to demonstrate the continuity of customs and morals, but also to show that these beliefs distorted or ran contrary to Christian doctrine. Sometimes the acts characteristic of Gello were attributed to "poor and miserable old crones," who could be accused in court as gelloudes and might even claim or confess to have acted as such. In his Life of Tarasios, Ignatius the Deacon recounts an actual case in which two women were charged as gelloudes and brought before his subject's father, who acquitted
them. Penance
might be prescribed for confessed
gelloudes, and is found specified in a few Nomocanon
s, or collections of ecclesiastical law. Michael Psellos, however, rejected the notion that human beings could transform into demonic beings, and so there would be no need for a particular penance; the official position of Orthodoxy was that such creatures did not exist.
Despite her official non-existence, the gello is named in exorcisms, which required the attendance of a priest
, and in prayer formularies
. The Virgin Mary
is invoked against the child-harming demon gylo:
In one exorcism of the gello, no fewer than 36 saints are invoked by name along with Mary and the "318 Saints of the Fathers", with a final addendum of "all the saints." Some prayers resemble magic spells in attempting to command or compel the saints, rather than humbly requesting aid. Exorcisms emphasize that Christian families deserve exclusive protection. Gello continued to be named in exorcisms into the 20th century.
In early Christianity, a program of exorcism was preliminary to baptism as a kind of purification
and to drive away evil spirits, and not necessarily because the person was thought to be possessed
. The ambiguous state of the unbaptized is expressed by conflicting views of the infant: that the newborn had not sinned, and that the newborn nonetheless bore the pollution of original sin and was thus closer to the Devil than to God. The travel writer Sonnini de Manoncourt
recorded that the Greeks called an unbaptized child drako (or dracon, "serpent
, python
, dragon
"). At baptism, the name Drako is shed and replaced with a Christian name. The names of Gylo include Chomodracaena, containing drakaina, "female dragon." In one text dealing with the gello, she is banished to the mountains to drink the blood of the drako; in another, she becomes a drako and in this form attacks human beings. In other texts, the child itself is addressed as Abouzin (Abyzou
).
In ancient and medieval medical texts, a child was thought to be conceived from the father's "seed" and the mother's blood. The gello, herself infertile and envious, aimed to drink blood, the source of fertility, and was attracted to the dangerous time of birth and recovery in part because the new mother was regarded in Judaeo-Christian tradition as unclean; this state of pollution was congenial to demons. As long as the infant remained exclusively within the birth mother's sphere of influence, it was vulnerable to female demons seeking blood. In the story of Melitene, sister of the saints Sisinnios and Sisynodorus, the child is in peril until it is "returned" to the hands of men. In one version, the gello swallows the child and must be forced by the male saints to regurgitate it alive. This cycle — death by swallowing, regurgitation, new life — may be symbolized in initiation ceremonies such as baptism, which marked the separation of the child from the taint of its mother's gello-attracting blood.
, a belief system that venerates Lucifer
. In The Bible of the Adversary by Michael W. Ford, she is associated with Lilith and represents Vampyrism
as a desire for eternal life.

).
In ancient and medieval medical texts, a child was thought to be conceived from the father's "seed" and the mother's blood. The gello, herself infertile and envious, aimed to drink blood, the source of fertility, and was attracted to the dangerous time of birth and recovery in part because the new mother was regarded in Judaeo-Christian tradition as unclean; this state of pollution was congenial to demons. As long as the infant remained exclusively within the birth mother's sphere of influence, it was vulnerable to female demons seeking blood. In the story of Melitene, sister of the saints Sisinnios and Sisynodorus, the child is in peril until it is "returned" to the hands of men. In one version, the gello swallows the child and must be forced by the male saints to regurgitate it alive. This cycle — death by swallowing, regurgitation, new life — may be symbolized in initiation ceremonies such as baptism, which marked the separation of the child from the taint of its mother's gello-attracting blood.
