gello either. However, in these texts, galactite is said to protect against either Megaira ("Envy"), or "frightful woman" (horrida mulier) who attacked infants. Early Byzantine amulets Some Byzantine amulets against female reproductive demons are said to depict the Gello. This is sometimes asserted as a rule of thumb, without providing reasoning. As no Byzantine amulet exists that actually labels the demon as a Gello or Gyllou, the inference is made these are Gello by association with other figures labeled in the amulets, namely the demon Abyzou, the Saint Sisinnios, or the Evil Eye of "Envy". Numerous early Byzantine amulets (6th to 7th century label its demon as "Abyzou" identifiable with Obyzouth, a demon that strangles newborns according to the 1st to 3rd century Greek text called the Testament of Solomon. This Abyzou (Obyzouth) has been equated with the Gello (Gyllou), albeit in later literature, for example, the writings of Michael Psellos of the 11th century. Some Byzantine amulets also invoke the name of Saint Sisinnios, who is known foremost as the vanquisher of Gello. Again, the textual evidence that connect Sissinios to Gylou are from much later dates, the oldest version of the "Melitine charm" or Legend of St. Sisinnios dating to the 15th century. A concrete example is the Schlumberger No. 1 amulet shown on the right. Several scholars have hinted that the she-demon here, which has been noticed to have fish- or serpent-like attributes below the waist, may refer to Gello-Gyllou. The demon is being stabbed with a lance by a mounted figure (sometimes called the "holy rider" or "rider saint") which may be St. Sisinnios or Solomon. The inscription reads "Flee, detested one, Solomon, Sisinnios and Sisinnarios pursue you". The same amulet has a second side, which depicts an eye as "Envy" (phthonos, ), attacked by weapons and animals. One of the commentator has specifically connect the Evil Eye of Envy with the Gylou, while the others connect it more vaguely to the child-stealing demon or say that the beings labeled "Envy" are the ghost-demons (aōrē). Envy and Evil eye Gello or Gylou's curse has been associated with the evil eye of Envy at least since the Byzantine period, according to commentators. Sarah Iles Johnston views the Phtonos eye on the amulet and the Megaera ("Envious One") invoked in the entry for "galactite" in one Lithica (book of stones), as not just a personfification of "Envy" but
