Josephus - hand signals

[Matt Lukes]

But the question isn't whether there were ANY hand signals, but whether Caesar's motion to quench the fire was, yes? "Quench the Fire" doesn't seem to me to be a kind of hand signal that would be among the probably few that might have been used- the one Robert's reference mentions is 'HALT'- definitely a practical signal. Or am I completely missing what you were getting at Jim? I'm not familiar with the context of the quote- was fire part of a mission or plan? If so, and putting it out at some point was important, then sure coming up with a signal for that makes sense, but otherwise?
