Christianity is still for 400,000,000 of human beings the great pair of wings that are indispensable if man is to rise above himself, above humdrum living and shut-in horizons, it is still the spiritual guide to lead him by patience, resignation, and hope to serenity, to lift him by purity, temperance, and goodness to the heights of devotion and self-sacrifice. Always and everywhere for nineteen hundred years as soon as these wings flag or break, public and private manners degenerate. Neither philosophy, reason, nor artistic and literary culture, nor even feudal honor, military and chivalrous, no code, no administration, no government can serve as substitute for it.--H. TAINE (1892). The church of St. Louis, at Poissy, is a link in the normal development of Gothic, and not like St. Germain, a disconcerting anachronism. About 1135 both systems of vaults were here built at one and the same time. Poissy lies on the Seine slightly above its junction with the classic Oise. A pleasant way to approach it is to walk from St. Germain-en-Laye through the forest, when it is carpeted with anemones. St. Germain's palace chapel is thought to be the work of Pierre de Montereau. One goes to Poissy in a spirit of pilgrimage, for at its font, in 1215, St. Louis of France was baptized.[29] He held the gift of Christian citizenship he here received above all that the world could bestow. To his intimates he often signed himself Louis of Poissy. His grandfather, Philippe-Auguste, had given the manor of Poissy to his son, on his marriage to Blanche of Castile. Living then in retirement at Poissy was the gentle Agnes of Méran, that aunt of St. Elizabeth of Hungary whom Philippe-Auguste had been forced by Rome's decree to set aside. When St. Louis was born, on St. Mark's Day of 1215, in order to spare the young mother, the church bells were silent. The Spanish princess asked the cause, and ordered--gallant woman that she was--that every bell in the town should ring out a joyous carillon because God had given her _un beau fils_. Shakespeare would inevitably admire Blanche; she was a Shakespearian character: That daughter there of Spain, the hardy Blanche, Is near to England; look upon the years Of Louis the Dauphin and that lovely maid. If lusty love should go in search of beauty, Where shall he find it fairer than in Blanche? If jealous love should go in search of virtue, Where shall he find it purer than in Blanche? If love ambitious sought a match of birth, Whose veins bound richer blood than Lady Blanche?[30]
