It will be seen, by reference to the Appendix, that though the architects consulted were fairly unanimous as to the possibility of building the single nave, they were by no means so in their recommendation of it as the best plan. The general feeling seems to have been decidedly adverse to it; and we may assume that the Chapter decided on it partly because it was already commenced, and partly because it promised to be a cheaper plan than the other. There seems also to have been great dread on the part of the Chapter of interfering in any way with the wall which now forms the east end of the nave, for fear lest, when it was cut into for the introduction of the respond of the nave arcade, the whole should give way. Paschasius de Xulbe, one of the architects questioned, gives the valuable answer, that if the nave is of triple division in width, the groining of the choir must be raised in order that it may correspond in its measurements to its third; from which it is pretty clear that he spoke of a then recognized system of proportioning the height to the width of a building. Guillermo Sagrera, master of the works at St. John Perpiñan, tells us, in his answer, that the choir was originally built with the intention of having a single nave; and this will account for the otherwise unintelligible finish of its western wall, which it is clear, from the tenour of all the answers, was not prepared for any arches in the nave. I am not certain indeed whether we are not to assume, in reading the questions asked by the Chapter, that the Romanesque nave was itself of the same plan and dimensions; and the vast width of the old nave of Toulouse Cathedral--sixty-three feet--affords an example, at no great distance from Gerona, of the fact that architects, even so early as the beginning of the thirteenth century, were not afraid to propose and execute works on so unusual a scale. I will not quote farther from the answers of the architects, because they well deserve to be read in detail; but it is a satisfaction to be able to say that their conviction of the practicability of the work has been amply justified, inasmuch as, even to the present day, there is scarcely a sign of a settlement or crack throughout the entire building.
