The first edition of this tale was put forth without explaining the old fable on which it was founded - a fable recurring again and again in fairy myths, though not traceable in the classic world till a very late period, when it appeared among the tales of Apuleius, of the province of Africa, sometimes called the earliest novelist. There are, however, fragments of the same story in the popular tales of all countries, so that it is probable that Apuleius availed himself of an early form of one of these.
