The interest of the Fabliaux as a literary study is increased by the precision with which they can be defined, and the well-marked period of their composition. According to the excellent definition of its latest editor, the Fabliau[61] is 'le recit, le plus souvent comique, d'une aventure reelle ou possible, qui se passe dans les donnees moyennes de la vie humaine,' the recital, for the most part comic, of a real or possible event occurring in the ordinary conditions of human life. M. de Montaiglon, to be rigidly accurate, should have added that it must be in verse, and, with very rare, if any, exceptions, in octosyllabic couplets. Of such Fabliaux, properly so called, we possess perhaps two hundred. They are of the most various length, sometimes not extending to more than a score or so of lines, sometimes containing several hundreds. They are, like most contemporary literature, chiefly anonymous, or attributed to persons of whom nothing is known, though some famous names, especially that of the Trouvere Ruteboeuf, appear among their authors. Their period of composition seems to have extended from the latter half of the twelfth century to the latter half of the fourteenth, no manuscript that we have of them being earlier than the beginning of the thirteenth century, and none later than the beginning of the fifteenth. If, however, their popularity in their original form ceased at the latter period, their course was by no means run. They had passed early from France into Italy (as indeed all the oldest French literature did), and the stock-in-trade of all the Italian _Novellieri_ from Boccaccio downwards was supplied by them. In England they found an illustrious copyist in Chaucer, whose Canterbury Tales are perfect Fabliaux, informed by greater art and more poetical spirit than were possessed by their original authors. In France itself the Fabliaux simply became farces or prose tales, as the wandering reciter of verse gave way to the actor and the bookseller. They appear again (sometimes after a roundabout journey through Italian versions) in the pages of the French tale-tellers of the Renaissance, and finally, as far as collected appearance is concerned, receive their last but not their least brilliant transformation in the _Contes_ of La Fontaine. In these the cycle is curiously concluded by a return to the form of the original. [Sidenote: Subjects and character of Fabliaux.]
