“Unveiling the Blood and Glory: The Untold Realities of Life as a Gladiator in Ancient Rome”
As to voicing their thoughts, the fate of a gladiator, in terms of whether the audience was voting for a kill, was decided with what is known as “pollice verso”, a Latin term which roughly translates to “turned thumb”. More precisely what this means isn’t known and there are no accounts that have survived to this day that describe it in any real detail. As such, we’re unable to say for sure which way the thumb was supposed to be pointed if the audience wanted a given gladiator to be killed or if they could just wave their thumbs around at random, which it seems may well have been the case.
So that’s voting for death, what about life? The gesture to spare a given gladiator’s life seems to have been neither a thumbs up nor a thumbs down. Instead, you had to hide your thumb inside your fist, forming a gesture known as pollice compresso, “compressed thumb”.
The reasons for this has been speculated to be twofold: one, it made the decision of the crowd easier to discern, since it’s easier to tell the difference between a thumbs turned and a closed fist than a thumbs up and a thumbs down from a long ways away. And two, the gestures themselves are thought to be largely symbolic of what they represented- a pointed thumb represented the audience’s desire for the victorious gladiator to deliver his coup de grâce (stab the fallen foe), while a hidden thumb symbolised that they wished for the gladiator to stay his blade, sheathing it much in the way they’d hidden their thumbs. Hence why it’s thought “turned thumb” may well have been simply waving your thumb around in the air, perhaps in a stabbing motion.
