This was clearly realized by the more intelligent upholders of the Feast of Fools. Austere persons wished to abolish this Feast, and in a remarkable petition sent up to the Theological Faculty of Paris (and quoted by Flogel, Geschichte des Grotesk-Komischen, fourth edition, p. 204) the case for the Feast is thus presented: "We do this according to ancient custom, in order that folly, which is second nature to man and seems to be inborn, may at least once a year have free outlet. Wine casks would burst if we failed sometimes to remove the bung and let in air. Now we are all ill-bound casks and barrels which would let out the wine of wisdom if by constant devotion and fear of God we allowed it to ferment. We must let in air so that it may not be spoilt. Thus on some days we give ourselves up to sport, so that with the greater zeal we may afterwards return to the worship of God." The Feast of Fools was not suppressed until the middle of the sixteenth century, and relics of it persisted (as at Aix) till near the end of the eighteenth century.
A Méray, La Vie au Temps des Libres Prêcheurs, vol. ii, Ch. X. A good and scholarly account of the Feast of Fools is given by E. K. Chambers, The Mediæval Stage, Ch. XIII. It is true that the Church and the early Fathers often anathematized the theatre. But Gregory of Nazianzen wished to found a Christian theatre; the Mediæval Mysteries were certainly under the protection of the clergy; and St. Thomas Aquinas, the greatest of the schoolmen, only condemns the theatre with cautious qualifications.
