'lignum illud, quo per radios rotarum trajecto; vel ferreum instrumentum in modum soleæ formatum, quo subter notæ unius canthum supposito, currus in declivibus locis nimio impetu ruentes cohibentur: illud Itali stanga, hoc scarpa vocant.
There can be no doubt, then, as to the Romans possessing such an instrument to facilitate the travelling of their carriages; but I do not remember any mention being made as to their discovery anywhere; and in all likelihood we have them here. I am aware that in a sepulchral bas-relief found at Langres, representing, among other objects, a cart drawn by three horses, two chains are seen attached to the body of the carriage, and in front of the hind wheel, one with a ring, the other with a hook at the end to lock round the felloe between two of the spokes, and make a fetter for the wheel. So says Mr Rich; but this kind of contrivance would, one is inclined to think, be of as limited application in the Romano-Gallic days as now. It is a most expensive way of staying the velocity of a carriage. The shape of the supposed sandals presents but little difference from that of the skid or wheel-shoe of now-a-days, except, perhaps, in length.
The drawing of one of those attached to the waggons of the Military Train will make this manifest (fig. 137).
