The article that follows is the result of two years spent in Italy under a scholarship of the British School at Rome. The writer's original intention was to attempt a general study of ancient bridge-construction in Italy. It soon became obvious, however, that this was an almost impossible task, owing to the lack of adequately published material. On the great roads leading out of Rome, comparatively little original work has been done in the last thirty years; and if the destruction of ancient roads and of their attendant structures continues for much longer at the present rate, there will soon be little left to publish. The damage done during the late war was very considerable; and although a damaged bridge may in some ways be more rewarding than an intact one, a bridge that has been both damaged and reconstructed is of very little archaeological interest indeed.
For these reasons, it has seemed that the immediate need is not so much for a general work, which would necessarily be incomplete, as for a straight-forward description of the remains of bridges along some part of the ancient road-system of Italy, together with such comment as seems necessary to point out the problems involved.
