Pollex versus - pollex presso etc.

[Velite]

Dear all,

I look for images that help me to find out what they were really doing these important gestures that were routine in all the arenas in the Roman Empire

Thanks for helping me give, for the information and your views on this issue and I ask you:
How these gestures were made which expressed "death" or "life" of the defeated gladiators?

I found this site http://penelope.uchicago.edu/Thayer/E/R ... erso*.html

in which assumptions are made and where there is a very interesting picture where you see the judge (right in photo) that makes a particular gesture: Raise the hand with thumb inside the closed fist.

What do you think?

Valete

Excuse me for my very bad English :roll:
