In his short pontificate, 1262-64, Urban IV, besides creating this enduring memorial, instituted the feast of Corpus Christi. He requested a liturgy for his new feast from St. Thomas Aquinas, who composed the _Pange lingua gloriosi_, the last stanzas of which are sung daily throughout the Christian world, the familiar _Tantum ergo_. To Aquinas is ascribed the _Verbum supernum prodiens_ hymn whose ending is the lovely _O Salutaris Hostia_. Doubt and heresy have always been instrumental in clarifying doctrine and in enriching the liturgy and art. So in a later day was made, in reaction against the XVI-century desecration of the Eucharist, such windows as the Wine Press of Troyes and that of Conches. In 1906, soon after St. Urbain's church had celebrated the completion of its western portal, it became the scene of a conscientious objection on the part of its parishioners, who protested against the taking of an inventory, they deeming it an unlawful interference with their private affairs. They sat in their church till the police broke in the doors; even then they continued to sing canticles, and were expelled only by having a hose turned on them. Six centuries earlier, St. Urbain's had been the scene, on the completion of its choir, of a suffragette-like demonstration by a community of nuns, who claimed part of the land on which the church stood. They smashed various things on the premises, and, it is whispered, even slapped a high dignitary's face. Apparently St. Urbain's is destined to pass into history under various aspects. For four hundred years the ancient capital of Champagne was an active center of the stained-glass industry. Overpowering is the wealth of storied windows to be found in its churches, the majority being of the Flamboyant-Renaissance day. In the suburbs, and farther afield in the hamlets of Champagne, there is the same prodigal display of colored windows and interesting statues.[148] From father to son, from generation to generation, was passed on the art skill of this ancient city on the highway of international trade. In Troyes there were so many churches that the old saying ran: "You arrived from Troyes? And what are they doing there?" "_On y sonne._" Next to St. Urbain's, for its wealth of art treasures, comes the Madeleine church built about 1175, and reconstructed during the Flamboyant enthusiasm when this city readorned almost every shrine it possessed. Contemporary with its noted _jubé_, or rood screen (1508-17), is the statue of St. Martha, one of the gems of French sculpture, entirely of the national school, unaffected work as ample and robust as the best period of the XIII century. St. Martha is represented, in this church of Troyes dedicated to her sister, with the holy water by which she exorcised the legendary Tarasque of Tarascon. She was the patroness of housekeepers, and it is said that the servant maids of Troyes presented to their church this memorial of the plastic genius of Champagne.[149]
