[Footnote 21: It was a favorite occupation some few years ago to pick out what were considered the ten best books. Sir John Lubbock first suggested, that it would be an interesting thing to pick out the ten books which, if one were to be confined for life, should be thought the most likely to be of enduring interest. If this favorite game were to be played with the selection limited to the authors of a single century, it is reasonably sure that most educated people would pick out the thirteenth century group of ten for their exclusive reading for the rest of life, rather than any other. An experimental list of ten books selected from the thirteenth century writers would include the Cid, the Legends of King Arthur, the Nibelungen Lied, the Romance of the Rose, Reynard the Fox, the Golden Legend, the Summa of St. Thomas Aquinas, Parsifal or Perceval by Wolfram von Eschenbach, Durandus's Symbolism and Dante. As will readily be appreciated by anyone who knows literature well, these are eminently books of enduring interest. When it is considered that in making this list no call is made upon Icelandic Literature nor Provençal Literature, both of which are of supreme interest, and both reached their maturity at this time, the abounding literary wealth of the century will be understood.] {210} It has become the fashion in recent years, to take the pains from time to time to find out which are the most read books. The criterion of worth thus set up is not very valuable, for unfortunately for the increase in readers, there has not come a corresponding demand for the best books nor for solid literature. The fact that a book has been the best seller, or the most read for a time, usually stamps it at once as trivial or at most as being of quite momentary interest and not at all likely to endure. It is all the more interesting to find then, that these three most read books of the Thirteenth Century, have not only more than merely academic interest at the present time, but that they are literature in the best sense of the word. They have always been not only a means of helping people to pass the time, the sad office to which the generality of books has been reduced in our time, but a source of inspiration for literary men in many generations since they first became popular. The story of Reynard the Fox is one of the most profoundly humorous books that was ever written. Its satire was aimed at its own time yet it is never for a moment antiquated for the modern reader. At a time when, owing to the imperfect development of personal rights, it would have been extremely dangerous to satirize as the author does very freely, the rulers, the judges, the nobility, the ecclesiastical authorities and churchmen, and practically all classes of society, the writer, whose name has, unfortunately for the completeness of literary history, not come down to us, succeeded in
