 p172  XCVIII. The light troops cross a temporary bridge

The orders of one of the praetorian officers have set in motion a portion of the Roman troops. They cross a stream. The bridge is formed by driving piles into the bed of the river and laying timbers on them, with a road of planking nailed thereon. The piles are three together in the deeper and more rapid portions of the stream, and two together as they near the opposite shore. The heads of the piles meet in one large transverse timber laid in the direction of the stream, and the planks are laid across from one of these to the other. This bridge is identical in construction with the bridge thrown by Julius Caesar across the Rhine,  p173 and of which detailed drawings are given by A. Palladio.​37 This stream appears to be a tributary to a considerable river.
