Rome (the TV series)

[lobf]

I was watching the very first episode of this series and they showed the Roman armies fighting in a formation where they were in a block and the front row rotated to the back on a signal. Does anyone know whether they fought like this?

Fact is, nobody knows for certain how a battle-line acted. HBO presented one idea in their show.

boxers try to land huge hits on their opponents, and this takes considerable energy (too).

No we don't. There's much more technicality than just throwing the biggest blows you can.

There was indeed a rotating system. However I can't remember horns or how it precisely worked. But I rember that it was used.

I think you have a tendency to present hypothesis or hearsay as fact. You can't say you know how it works because nobody does.
