"For instance, the altar, which is the Image of Our Lord, must be draped with white linen in memory of the winding-sheet in which Joseph of Arimathea wrapped His body--and that linen must be woven of pure thread, of hemp or flax. The chalice, which according to the texts adduced by the _Spicilegium_ of Solesmes, is to be taken now as a symbol of glory, and now as a sign of opprobrium, may be regarded, by the most generally received theory, as the figure of the sacred Tomb; then the paten appears as the stone which served to close it, while the corporal is the shroud itself. "When I tell you further," added the Abbe, "that according to Saint Nilus, the columns signify the divine dogmas, or, according to Durand of Mende, the Bishops and the Doctors of the Church, that the capitals are the words of Scripture, that the pavement of the church is the foundation of faith and humility, that the ambos and rood-loft, almost everywhere destroyed, figure the pulpit of the gospel, the mountain on which Christ preached; again, that the seven lamps burning before the altar are the seven gifts of the Spirit, that the steps to the altar are the steps to perfection; that the alternating choirs represent on the one side the angels, and on the other the righteous, combining to do homage with their voices to the glory of the Most High, I have pretty well explained to you the general meaning and detailed symbolism of the interior of the cathedral, and more particularly that of Chartres. "Now you must observe a peculiarity which is also to be seen in the Cathedral at Le Mans; the side aisles of the nave in which we are sitting are single, but they are double round the choir--" But Durtal was not listening; far away from this architectural exegesis, he was admiring the amazing structure without even trying to analyze it. Wrapped in the mystery of its own shadow thick with the haze of rain, it soared up lighter and lighter as it rose in the skyey whiteness of its arcades, aspiring like a soul purifying itself with increasing light as it toils up the ways of the mystic life. The clustered columns sprang in slender sheaves, their groups so light that they looked as if they might bend at a breath; yet it was not till they had reached a giddy height that these stems curved over, flying from one side of the Cathedral to the other to meet above the void, mingling their sap and blossoming at last, like a basket of flowers, in the once gilt pendants from the roof. This church appeared as a supreme effort of matter striving for lightness, rejecting, as though it were a burden, the diminished weight of its walls and substituting a less ponderous and more lucent matter, replacing the opacity of stone by the diaphanous texture of glass.
