Reading edition
According to Arrian, the besieged lost heart not from terror of the engines, but on seeing their commander killed. We read in Caesar that his engines produced a similar effect on the minds of the Gauls. They said that they could not believe the Romans were warring without the help of the gods since they were able to move forward engines of so great a height and with such celerity (De Bell. Gall. ii. 31).
