Frank Brangwyn has drawn for us, with as much fidelity as vigour, one of the finest gable bridges, the Puente de San Juan de las Abadesas at Gerona. This bridge has a great historic interest. The Moors left in Spain a peculiar grace of style which native architects often united to their own qualities--a haughty distinction and a lofty ambition. Consider the immense nave in Gerona Cathedral, a glorious pointed arch not less than seventy-three feet from side to side, almost double the width of Westminster nave. It belongs to the fifteenth century, yet in the magic of its youthful hope it proves that its architect, Guillermo Boffiy, was a child of the thirteenth. And the great central arch of the Gerona bridge has in it some of the soaring courage that transcends all expectation in the cathedral nave[7]. Yet this gabled bridge, though very spacious and attractive, has less charm than its rival at Orense, in Gallicia, a noble monument 1319 feet long, built in 1230 by Bishop Lorenzo, and repaired in 1449 by Bishop Pedro de Silva. The six arches differ in size, yet their combination is symmetrical; four are gracefully pointed, and the finest one rises above the Miño to a height of a hundred and thirty-five feet, and its brave span, a hundred and fifty-six feet from pier to pier, is the widest of any in Spain.[8] [Illustration: PUENTE DE SAN JUAN DE LAS ABADESAS AT GERONA, SPAIN] It is commonly supposed that gable bridges were invented by the genius of Gothic architecture. Yet Marco Polo found them in China,[9] and the Roman bridge of two arches at Alcantarilla is hog-backed. Usually the Romans liked a flat road over a river, though it was easier and less expensive to build a steep bridge from low embankments. But the bridge at Alcantarilla, about twenty miles below Seville, is quite steep enough to be the forerunner of all the gable bridges erected in Spain.[10]
