An anonymous commentator on the passage states this is a reference to the Lamia, but muddlingly combines this with Aristotle's subsequent comments and describes her as a Scythian of the Pontus (Black Sea) area. According to one myth, Hera deprived Lamia of the ability to sleep, making her constantly grieve over the loss of her children, and Zeus provided relief by endowing her with removable eyes. He also gifted her with a shapeshifting ability in the process. Diodorus' rationalization was that the Libyan queen in her drunken state was as if she could not see, allowing her citizens free rein for any conduct without supervision, giving rise to the folk myth that she places her eyes in a vessel. Heraclitus's euhemerized account explains that Hera, consort of King Zeus, gouged the eyes out of the beautiful Lamia. Lamia was the daughter born between King Belus of Egypt and Lybie, according to one source. According to the same source, Lamia was taken by Zeus to Italy, and that Lamos, the city of the man-eating Laestrygonians, was named after her. A different authority remarks that Lamia was once queen of the Laestrygonians. Aristophanes wrote in two plays an identically worded list of foul-smelling objects which included the "Lamia's testicles", thus making Lamia's gender ambiguous. This was later incorporated into Edward Topsell's 17th century envisioning of the lamia. It is somewhat uncertain if this refers to the one Lamia or to "a Lamia" among many, as given in some translations of the two plays; a generic lamia(s) is also supported by the definition as some sort of a "wild beast" in the "Suda". The "Lamia" was a bogeyman or bugbear term, invoked by a mother or a nanny to frighten children into good behavior. Such practices are recorded by the 1st century Diodorus, and other sources in antiquity. Numerous sources attest to the Lamia being a "child-devourer", one of them being Horace. Horace in "Ars Poetica" cautions against the overly fantastical: "[nor should a story] draw a live boy out of a Lamia's belly". Lamia was in some versions thus seen as swallowing children alive, and there may have existed some nurse's tale that told of a boy extracted alive out of a Lamia.
