How far each of these names may be applied in general to all the classes of pagan gods and demons and monsters whom I am about to describe is a question which I cannot determine. On the one hand many of the names, as we have seen, are purely local, confined to a few villages or districts or islands and unknown and unintelligible elsewhere: and on the other hand some of these supernatural beings themselves are equally local, and my information concerning them has been gathered from widely separated regions of the Greek world. Hence it follows that while the several terms which I have explained are comprehensive in local usage and include all the supernatural beings locally recognised, it is impossible to say whether the users of them would think fit to extend them to the deities of other districts. Probably they would do so; but only for the most widely current terms, δαιμόνια and ἐξωτικά, can I claim with assurance anything like universal application. The surviving pagan deities fall naturally into two classes. There are the solitary and individual figures such as Demeter, and there is the gregarious and generic class to which belong for example the Nymphs. An exceptional case may occur in which some originally single personality has been multiplied into a whole class. The Lesbian maiden Gello, who, according to a superstition known to Sappho[127], in revenge for her untimely death haunted her old abodes preying upon the babes of women whose motherhood she envied, is no longer one but many; the place of a maiden, whom death carried off ere she had known the love of husband and children, has been taken by withered witch-like beings who none the less bear her name and resemble her in that they light, like Harpies, upon young children and suck out their humours[128]. But in the main the division holds; there are single gods and there are groups of gods. Of the former, in several cases, there is very little to record. Such memory of them as still lingers among the people is confined perhaps to a single folk-story out of the many that have been preserved. In such cases I do not feel entire confidence that the reference is a piece of genuine tradition; in spite of the popular form in which the stories are cast, it is always possible that, owing to the spread of education, some scholastic smatterings of ancient mythology have been introduced by the story-teller. There are certainly plenty of tales to be heard about Alexander the Great which are drawn from literary sources; and it is possible that two stories published by Schmidt which contain apparent reminiscences of Poseidon and of Pan are vitiated, from the point of view of folklore, in the same way. Fortunately the cases in which this reserve must be felt are few and in the nature of things unimportant: for, though proof of genuine tradition would be interesting, yet a single modern allusion is not likely to throw any light on the ancient conception of a deity or his cult.
