Much more might be written on bridge chapels and crosses, but this monograph is only a brief introduction to a vast subject, and we must pass on to the other topics after noting two points more. Both concern the sanctification of bridges by means of religious emblems. It seems quite certain that the fourteenth and fifteenth centuries were most favourable to wayside crosses. By then very popular saints had been added to the old shrines, and the custom of making pilgrimages was tormented by fewer dangers, as a rule. Many a cross was a simple thing of wood fixed in a stone base, and sometimes it carried at top a small wind vane or weathercock. Many crosses were raised to commemorate historical events, while others were put up by sinners who wished to announce their repentance. Here and there a beautiful cross became celebrated. For example, the Belle Croix on the old bridge at Orléans was a nobly modelled crucifix of bronze that stood up high from the buttress of the middle pier; its pedestal was ornamented with low-reliefs representing the Holy Virgin, St. Peter, St. Paul, St. James, St. Stephen, and the bishops St. Aignan and St. Euverte. As we have seen (p. 230), the centre of a mediæval bridge was marked invariably by a cross. To-day, on the Continent, this old religious custom gives grace to a few bridges, and I value a large photograph of Trier Bridge over the Moselle, where the Virgin is enniched above the middle buttress, and where a crucifix, flanked by two columns, rises above the parapet. Yet we must not rush to the conclusion that this old sacred custom had its original source in the Christian religion. At first it may have belonged to a faith in evil spirits, whose power for mischief may have seemed to be increased by every roadway that enabled them to pass over running water. I have by my side the photograph of a steep bridge in Western China, at Shih-Chuan, and here below the middle of the parapet is a small image of stone representing a tutelary god! To me it is a curious little bit of rude sculpture, all head and stomach and truncated thighs. Its position on the bridge corresponds with that of the cross on mediæval parapets--a fact of great interest.[103] Brangwyn depicts, in a very brilliant pen-drawing, a Chinese bridge larger and finer than the one at Shih-Chuan, but there is no image, so I set great store by the evidence of idolatry in the smaller bridge. [Illustration: STAIRCASE BRIDGE IN CHINA] Again, the province of Sichuan (pronounced Sit-you-on), in Western China, preserves another ancient custom. When a flood threatens to overwhelm a bridge, and particularly a bamboo suspension bridge, which is a common thing in the mountains, “the local official and the people throw a living pig into the river, to stay the rising water: the pig disappears, and the flood goes on.”[104]
