Abyzou is a female demon in the myths and folklore of both the Near East and Europe and was believed to be responsible for miscarriages and the deaths of babies and was said to be motivated by envy, as she herself was infertile. In the Hebrew tradition she is identified with Lilith, in Coptic Egypt with Alabasandria, and in Byzantine culture with Gylou, but in various texts surviving from the syncretic magical practice of antiquity and the early medieval era she is said to have many or virtually innumerable names.
Abyzou (also spelled Abizou, Obizu, Obizuth, Obyzouth, Byzou etc.) is pictured on amulets with fish- or serpent-like attributes. Her fullest literary depiction is the compendium of demonology known as the Testament of Solomon, dated variously by scholars from as early as the 1st century AD to as late as the 4th.
