Selden asserts, and in my opinion with great justice, that all these whimsical transpositions of dignity are derived from the ancient Saturnalia, or Feasts of Saturn, when the masters waited upon their servants, who were honoured with mock titles, and permitted to assume the state and deportment of their lords. These fooleries were exceedingly popular, and continued to be practised long after the establishment of Christianity, in defiance of the threatenings and the remonstrances of the clergy, who, finding it impossible to divert the stream of vulgar prejudice permitted them to be exercised, but changed the primitive object of devotion; so that the same unhallowed orgies, which had disgraced the worship of a heathen deity, were dedicated, as it was called, to the service of the true God, and sanctioned by the appellation of a Christian institution. From this polluted stock branched out variety of unseemly and immoral sports; but none of them more daringly impious and outrageous to common sense, than the Festival of Fools, in which the most sacred rites and ceremonies of the church were turned into ridicule, and the ecclesiastics themselves participated in the abominable profanations.
