It's rumoured that they _did_ build some sort of pontoon out of barrels, to transport the elephants captured by Lucius Caecilius Metellus after the Battle of Panormus. The story's widely attributed to Strabo or Pliny the Elder but I can't find the original source, whether or not we'd believe it. Tip of the galea to whoever tracks it down.
