A book of bridges

LAROQUE ON THE RIVER LOT, NEAR CAHORS, A SORT OF INLAND GIBRALTAR; A PART OF THE VILLAGE IS BUILT ON BRIDGES THROWN ACROSS CHASMS IN THE ROCKS

Before we pass on from the defensive bridges, I should like to give you a picture of the famous old bridge at Saintes, in France, that lasted to the year 1843, when it was destroyed. I know not why I use the silly word “it,” for the bridge of Saintes was an exceedingly martial structure that united all the main phases of military art—the primitive, the Roman, and the mediæval. Let me give an abridged description from Viollet-le-Duc’s “Dictionnaire raisonnée d’Architecture”:—

“The first gate appeared on the right shore of the Charente, on the side of the Faubourg des Dames; next came the Roman arch, [127] the upper part of which was crenellated during the Middle Ages; next on the side of the town stood a tower of oval plan, through which the road lay; the town gates with flanking towers closed the end of the bridge. From the first gate to the Roman arch the bridge was of wood, as was also the case between the great tower and the town gates, so that by the removal of this part of the roadway all communication could be cut off between the town and the tower, as well as between the bridge and the Faubourg; moreover, the parapets were crenellated, so that the garrison of the town at any moment could stop all navigation.”

A brief introduction to the history of bridges has so many difficulties that I creep through my work, a few hundred words in a long day. To try to plant an oak tree in a thimble would be more difficult, I suppose, but gleaning here and there over vast fields brings trouble enough to any writer. I go through scores of photographs, and turn over great piles of notes, and seek for a topic that is not too technical for the general reader, but that touches a really important phase in the evolution of bridge-building. There is a species of bridge to which the arches at Laroque belong; it may be called either freakish or very exceptional. Let me give a few examples.

There is one at Crowland, a curious three-branched structure which for many a year stood at the confluence of the Catwater drain and two streamlets, the Welland and the Nyne. To-day no water flows under this bridge, and common little modern houses do not make pretty pictures when they are framed by the arches. There are three pointed arches, with their abutments at the angles of an equilateral triangle; they meet in the middle, and form three roadways and three watercourses. They have three stone ribs apiece, and the nine ribs meet in the centre I note, too, that these arches were built not by a bridgeman, but by a mason skilled in church work, for their rings are moulded elaborately as in Gothic windows and doorways. As for the style of architecture, it is not older than the beginning of the fourteenth century; but a much earlier bridge at Crowland, probably of wood, was famed for its triangular shape, and mentioned in a charter of the year 943, when Edmund was King.

At the south-west entrance of Crowland Bridge, beyond the five steps, there is a rough-hewn statue that represents a crowned and bearded figure seated up high against the parapet walls, in an attitude of sorrow, with arms folded (and perhaps they may be bound together) over a long robe. Time has frayed and scarred this uncouth sculpture, but not without leaving some mellow lines and planes. The archæology of guesswork has called this effigy by various names, such as Ethelbald, and Saint Guthlac, and Henry II, but I prefer to look upon it as a simple Pietà chiselled by a mason who had been trained to do enniched figures for church decoration—work without detail, to make at a distance a broad effect. This conjecture is in accord with the ecclesiastical moulding of the archstones, and with the mediæval custom that united bridges to Christianity by means of sacred emblems. Crowland Abbey ruled over the district, so one of the Abbots may have built the bridge; and perhaps the pointed arches, three in number, with their triple ribs, and their three pathways, and the three streams of water, may have been intended as symbols of the Trinity. If so,—and there is nothing in this view to clash with the spirit of the Mediæval Church,—then a Pietà turned toward the west would be the most beautiful symbol of that Light which went down with the sun, and then rose again through the dark into the dusk, and through the dusk into a dawn where faith for ever dwells. On the other hand, if the crowned figure represents a mere earthly king, I know not why Ethelbald should be chosen, for his reign of two years was not a creative time and he died in 860, just eighty-three years before Crowland’s triangular bridge was alluded to in the charter of the year 943. Alfred, Edward the Elder, and Athelstan—these kings in succession were nearer to the charter, and their longer reigns were more notable than the short hours of Ethelbald. Alfred we should prefer, of course, but he has been passed over by the busy minds that have weaved around Crowland Bridge so many cobwebs of the study and so much haze of idle conjecture. My own views are conjectures also, but they are taken partly from the bridge itself and partly from the care and affection that the Church during the Middle Ages bestowed on bridge-building.

And now a technical matter ought to be considered in its bearing on the arches of Crowland Bridge. At a time when bridges were protected by the Church, their arches were affected by changes of style in ecclesiastical windows and doorways; but, of course, whatever shape was given to them, they were treated differently from doorways and windows, for these had to bear only a downward thrust, while bridges had to withstand five trials: their own “spring,” the vibration caused by wheeled traffic, the lateral pressure of flowing water, the disturbance of gravity by immersion, and blows from drifting ice and timber. With these problems to be solved, bridgemen set no store by moulded archstones, a kickshaw of style. Sometimes they built the ring of an arch with two or three sets of voussoirs, [128] but their aim was practical, not ornamental; they wished to give greater resistance to their work, and not merely to spend time and money on a decorative effect. So when we find in the arches of Crowland Bridge such moulded handicraft as was used in church decoration, we may surmise that the architect and his masons were not bridge-builders, and that they worked only for the light foot-traffic of a village.

It is worth noting that in the year 1752 a French architect named Beffara took a hint from Crowland Bridge, and then achieved fame with a daring structure built near Ardres, in the Pas-de-Calais. There are four branches to this bridge, and they carry roads over two canals that intersect at right angles. One canal goes from Saint-Ouen to Calais and the other from Ardres to Gravelines. Beffara’s work is placed by Larousse among the fifty-four most notable bridges in the world, and this honour it seems to merit; but Frenchmen in their vanity have tried to make it into a pretentious bridge by giving to it a braggart name—Le Sans-Pareil. Gracious! It is fit for a café or for a battleship, in whose nomenclature bravado and bombast rule as customs. Poor Beffara! “Le Sans-Pareil,” like “Titanic” or like “Dreadnought,” defies the powers of Nature, inviting them to do their worst; and what good omen can there be in such bantam cockiness?

For a long time the old bridge at Bâle, over the Rhine, remarkable for its length and for its beautiful site, was not only freakish but exceedingly insolent. At one end, on the side of greater Bâle, was a tower decorated with a grotesque head called Laellenkoenig, which, in answer to the working of a clock, put out its tongue and rolled insulting eyes at the opposite bank. Eight or ten times an hour this abusive pantomime was repeated, and it never failed to anger little Bâle, which had the pugnacious vanity of a small organism. I do not know how many duels were fought, but at last a touch of Rabelaisian humour suggested a mechanical revenge, far more regular in its action than were fights and punctured bodies. A tall post was set up by the inhabitants of Bâle junior, and on the top of it stood a hateful statue that affected to turn its back on the enemy with a shameless movement.
