We next consider the arguments of the symbolists. Several solutions are offered by these authorities, though there is no great divergence of fundamental ideas. The favourite explanation, as just hinted, is that Christ, while on the Cross, faced Westwards, and that His head leaned towards the left, or South side. Another school teaches that the inclination was to the North, and, as we have already seen, such Continental churches as have varying axes, are deflected towards that point. In roods, it may be noted, the head is usually made to fall towards the left[582]. The “leaning-head” theory was accepted by Dr Rock. M. Huysmans has evidently paid so much attention to this phase of the question that he may be again quoted. Describing the fine abbey church of Preuilly-sur-Claise, in Touraine, he declares that the builders gave life to the stones. In its serpentine line, in the perspective of its aisles, and the obliquity of its vaulting, the church gives an allegorical presentment of Our Lord on the Cross, and perpetuates “the never-to-be-forgotten moment between the ‘Sitio’ and the ‘Consummatum est’[583].” M. Huysmans mentions, with reserve, the opinion of some writers, that the bent line occasionally represents the body of a saint instead of that of the Saviour; thus the curved axis of St Savin is supposed to be symbolical of the wheel which was the instrument of martyrdom of the saint[584]. There are not lacking authorities who, like Dr Cox, spurn these theories as idle fancies. “Symbolism!” exclaimed Welby Pugin, when viewing a twisted chancel in Leicestershire, “Pack of nonsense: it was because they didn’t know how to build straight[585].” This summary verdict, told by a person who heard it delivered, may, however, be countered by an opinion in the opposite sense, uttered by the same architect, and equally well attested. Asked about the bend in the nave at Whitby Abbey, which has just been mentioned, Pugin declared that it signified that the debt of redemption had been paid; “for, after the Saviour had expired on the Cross, his head would naturally lean or incline to one side[586].” Which of Pugin’s two opinions is the earlier cannot be ascertained, but even if antagonism to the “leaning head” theory were representative of his maturer judgement, he surely could not pretend that the deflection can always be ascribed to a blunder. Mr Parker himself, who advanced the theory that the twist might be due to the consecration of a building before its completion, admitted that many cases of deflection are incapable of a constructional explanation[587]. One may well ask whether the architects who reared our magnificent Gothic cathedrals, edifices whose every part, when untouched by the restorer, exhibits skill in design and workmanship, were really unable to build straight. What of the deflection at St Ouen, in the city of Rouen, a building which Fergusson enthusiastically declares was “beyond comparison the most
