§ 1. The idea of joining together a series of Tales by means of fitting them into a common frame-work is a very old one, and doubtless originated in the East. There is an English collection of this character known as 'The Seven Sages,' of which various versions have come down to us. The earliest of these, as published in the second volume of Weber's Metrical Romances, has been dated about 1320; and is, at any rate, older than any of Chaucer's poems. Another collection, of a similar character, and likewise of Eastern origin, is a Latin work by Petrus Alphonsus, a converted Spanish Jew, entitled De Clericali Disciplina. See Dunlop's History of Fiction, chap. vii. From one of these Chaucer may have taken the general idea of arranging his tales in a connected series; and we must not forget that his Legend of Good Women, which was the immediate forerunner of his greater work, is likewise, practically, a collection of Tales, though sadly lacking in variety, as he discovered for himself in the course of writing it. It is highly improbable that he was indebted for the idea to Boccaccio's Decamerone, as has been sometimes hastily suggested; since we might, in that case, have expected that he would also have drawn from that collection the plot of some one of his tales; which is not found to be the case. The Clerk's Tale occurs, indeed, in the Decamerone; but we know it to have been borrowed from Petrarch's Latin version of it. The Franklin's Tale has some resemblance to another tale in the same collection, but was evidently not taken from it directly, and the same is true in other cases; so that we are quite justified in supposing that Chaucer was wholly unacquainted, at first hand, with Boccaccio's work. § 2. It was suggested by Professor Seeley that we may profitably compare the form of Chaucer's Prologue with that of the somewhat similar Prologue to William's Vision concerning Piers the Plowman, a work which was very popular in England just at the same time. William introduces us to a Vision, in which he first of all beholds a Field full of Folk, and describes, in succession, the various sets of folk of which the company consisted; such as ploughmen, anchorites, hermits, chapmen, minstrels, beggars, pilgrims, palmers, friars, a pardoner, parish-priests, bishops, lawyers, and stewards. Chaucer seized upon the happy idea of limiting each class to a single individual, and the still happier idea of combining them into a company with a common object which allowed them to associate together on nearly equal terms. And having thus chosen his representative of each class, he employed his wonderful dramatic power in producing an exact description of each; so that, to quote the words of Dryden, 'he has taken into the compass of his Canterbury Tales the various manners and humours (as we now call them) of the whole English nation, in his age.'
