With regard to some of the Jātakas, among which may certainly be included those found in the Pāli Piṭakas, there may well have been a tradition, more or less reliable, as to the time and the occasion at which they were supposed to have been uttered by the Buddha. These traditions will have given rise to the earliest Introductory Stories, in imitation of which the rest were afterwards invented; and these will then have been handed down as commentary on the Birth Stories, till they were finally made part of our present collection by its compiler in Ceylon. That (either through their later origin, or their having been much more modified in transmission) they represent a more modern point of view than the Birth Stories themselves, will be patent to every reader. There is a freshness and simplicity about the ’Stories of the Past’ that is sadly wanting in the ‘Stories of the Present’; so much so, that the latter (and this is also true of the whole long Introduction containing the life of the Buddha) may be compared more accurately with mediæval Legends of the Saints than with such simple stories as Æsop’s Fables, which still bear a likeness to their forefathers, the ‘Stories of the Past.’ The Jātakas so constituted were carried to Ceylon in the Pāli language, when Buddhism was first introduced into that island (a date that is not quite certain, but may be taken provisionally as about 200 B.C.); and the whole was there translated into and preserved in the Siŋhalese language (except the verses, which were left untranslated) until the compilation in the fifth century A.D., and by an unknown author, of the Pāli Jātaka Book, the translation of which into English is commenced in this volume. When we consider the number of elaborate similes by which the arguments in the Pāli Suttas are enforced, there can be no reasonable doubt that the Buddha was really accustomed to teach much by the aid of parables, and it is not improbable that the compiler was quite correct in attributing to him that subtle sense of good-natured humour which led to his inventing, as occasion arose, some fable or some tale of a previous birth, to explain away existing failures in conduct among the monks, or to draw a moral from contemporaneous events. It is even already possible to point to some of the Jātakas as being probably the oldest in the collection; but it must be left to future research to carry out in ampler detail the investigation into the comparative date of each of the stories, both those which are called ‘Stories of the Past’ and those which are called ‘Stories of the Present.’
