Internal dissensions grew sharper. The extremists made use of the lawless Paris rabble against the more moderate element and a number of prominent Girondists were seized and plunged into the Conciergerie only to leave it to march singing to the guillotine. Marat’s death by the knife of Charlotte Corday could not stay the turmoil. There were grades of radicalism even among the extremists. The most advanced struck at the very basis of social agreement. Religion they declared out of date and substituted the worship of Reason. The Goddess of Reason, a dancer, they installed with her satellites in the most sacred part of Notre Dame, Saint Eustache became the Temple of Agriculture, Saint Gervais the Temple of Youth, Saint Étienne-du-Mont the Temple of Filial Piety, Saint Sulpice the Temple of Victory. Other sacred buildings were put to more practical uses--the Convent of the Cordeliers became a medical school, the Val-de-Grâce a military hospital, Saint Séverin a storehouse for powder and saltpeter, Saint Julien, a storehouse for forage, the Sainte Chapelle a storehouse for flour. The observation of Sunday as a day of rest was abolished, and men and animals died of fatigue. Many churches were closed, for “We want no other worship than Liberty, Equality and Fraternity,” cried the radicals. Robespierre of a sudden took a stand against such a display of irreligion, probably that he might have yet another accusation to bring against his enemies. To replace the Cult of Reason he established with grotesque rites a Worship of the Divine Being, acting himself as the high priest. The ceremony took place in the Tuileries Garden where there is still standing the stone semicircle built for the occasion. Robespierre was adorned with a blue velvet coat, a white waistcoat, yellow breeches and top boots and he carried a symbolic bouquet of flowers and ears of wheat. After he had made a speech there were games and the burning of effigies of Atheism, Selfishness and Vice. Destruction and change reigned. Churches were mutilated if the statue of some ancient saint wore a crown; the relics of Sainte Geneviève were burned on the Grève; the Academies were suppressed; no street might be named after a saint; no aristocrat might keep the _de_ of his name. The very calendar was altered, the new year beginning on September 22, 1792, which was the first day of the Year I of the Republic. The division of the year into twelve months was unaltered, but instead of weeks each month was divided into three decades of ten days each. This necessitated the addition at the end of the twelfth month of five extra days so that the new calendar might agree with that used by other peoples. These days were called by the absurd name, _Sansculottides_. The months were given names made appropriate by the season or the customary weather. They were:
