The most famous Fair of all was founded a little later by Guillaume Bonne Âme, forty-eighth bishop of Rouen, when he transported the body of St. Romain in a new and precious shrine from the church of St. Godard to the Cathedral. At this first procession in 1079 both William the Conqueror and his wife assisted. The change had been necessitated by the great crowds of people who had come every year to receive pardons and indulgences at the shrine of the famous guardian saint of the city, and who thronged into the neighbouring field, called the Champ-du-Pardon to this day. When the saint's body had been removed to the Cathedral, the Foire du Pardon was held in his honour in the same open space, and the whole ceremony was without doubt the beginning of that Levée de la Fierte which preserved the memory of St. Romain until the end of the eighteenth century. By William, the fair was originally fixed on two days in October, and in 1468 its duration was still further extended.[15] In the church of St. Étienne des Tonneliers, which was put under the protection of the monks of St. Ouen at this time, we can trace further evidence of the gradual consolidation of various trades; even the institution of the curfew bell, at the assembly of Caen in 1061, shows that increasing commerce had insisted upon greater security in the public streets. The Parvis of the Cathedral, too, was at this time not merely a place of inviolable sanctuary, but an open space on which merchants could display their goods and erect booths without any interference save from the canons. These shops were built up against the crenelated wall that surrounded the Parvis until the quarrel between canons and bourgeois pulled them down in 1192. The place was a frequent scene of conflict, and also of amusement, for in spite of the presence of a cemetery which extended over the Place de la Calende and the Portail des Libraires and was only abolished in the last century, the mystery plays were often given here, using the cemetery as a "background," as was frequently done. Till 1199 bakers sold bread here. Till 1429 the "Marché aux herbes et menues denrées" was held here, and then transferred to the Clos aux Juifs. In 1325 the working jewellers also frequented this locality, and in the name of the great north porch of the Cathedral is still preserved the memory of the booksellers of times far more modern.
