Tradition called for a girl carrying a baby to ride a donkey into a church while the congregation chorused hee-haw instead of Amen. It was only some 350 years after Jesus was born that newly Christian Rome put an end to centuries of squabbling and settled on December 25th as the date of the virgin birth (a few holdouts in the Orthodox church still prefer the January celebration). Across medieval Europe the escape valve opened every year, right on time. It became just another day under the new revolutionary calendar, which was used in France between 1793 and 1805. Roman life, normally so hierarchical, was turned on its head: slaves were served wine by their masters, cross-dressing was encouraged (the pantomime dame has ancient roots), and an ordinary man was elected King of the Saturnalia with the power to pass any law he fancied, so long as it was suitably hilarious.
