The Gladiator Rulebook
Gladiatorial games are the most commonly known form of entertainment in the Roman Empire as popular culture emulates these games of combat in forms such as films, novels, and games.
However, popular culture has caused many to unknowingly believe certain stereotypes, myths, and fallacies concerning gladiators, predominantly the gesture of a spectator or emperor pointing his thumb down to condemn a defeated gladiator or up to signify mercy. These stereotypes are a source of contention among historians in the field of ancient Roman entertainment and can prove to be problematic in discerning the truth of the fate of a gladiator. The root of the interpretation problem is the Latin phrase Pollice Verso, which is mentioned by ancient authors in regards to deciding a gladiator’s fate because it is scarcely referenced in ancient works and can be interpreted with different meanings.
Before the gestures to either spare or kill a gladiator were given, there had to be a victor and a loser. Gladiatorial fights were not entirely the bloody and brutal fights most people think of; studies done on the skeletons of gladiators indicate that they followed set rules of combat  and that the first gladiator to wound his opponent . The wounded gladiator would then raise his hand to the crowd and emperor, or presiding official, for them to determine his, or her , fate. The crowd would then yell and gesture and the emperor or presiding official would make the judgement which was almost always based on the audience’s reaction . This process is well-known among many and is not debated among historians. However, the contention appears in what the gestures for mercy or death actually were.
It is commonly agreed upon by historians that the gesture for death in some way involves the thumb. The ancient Romans declared that the thumb (pollice) had power (pollet) because it is used the most when compared to other fingers, especially in producing medicines, as well as the fact that to the Romans it represents a phallus which was also a prominent sign of power . The main question, however, is what exactly the gesture that gave the thumb the power of life and death was. Juvenal writes in his Third Satire “ . . . uerso pollice uulgus cum iubet, occidunt populariter” which translates to “with a turn of the thumb bids them slay” . Juvenal’s description of the gesture is commonly seen as the quote which led many to believe that a thumb pointed downwards symbolized death. On the other hand, Anthony Corbeill uses this quote from Juvenal as evidence that the thumb was actually extended upward to condemn the gladiator, which would be loosely supported by Pliny the Elder who wrote that they would turn down their thumbs to show approval  . However, conscientious of the unclarity, Corbeill also makes mention that the “turned thumb” may also refer to being extended towards one’s breast or downward .
Thumbs Down for Mercy?
The uncertainty of the gesture is noted again by Corbeill in his article “Thumbs in Ancient Rome: Pollex as Index” in which he mentions that historians had interpreted the gesture as the thumb being “lifted up, pointed down, hidden in the hand, directed at the chest, and squeezed between the middle and index finger” . Despite historians' attempts to clarify the uncertainty, the famous 1872 painting Pollice Verso, translated to “with a turned thumb”, by Jean Léon Gérôme condemned the modern masses to believe the stereotype that a thumb pointed downward meant death to a fallen gladiator. The picture depicts a gladiator standing above his wounded opponent looking onto the audience for them to decide his fate, while the first row of spectators is filled with Vestal Virgins pointing their thumbs downward with what some might say would be a look of concern on their face . At first glance, the viewer would imagine that the Vestal Virgins, as well as other spectators, are demanding the gladiator be slain, which is what many agreed upon and is why many still believe that a downward thumb meant death. However, a simple look at the virgins' faces would be cause to think otherwise, as their expressions do not look like that of those willing to condemn a man to death. The 1904 article “The Passing of Jean Leon Gerome” even mentions that it is known among academics that the gesture of pointing a thumb downward did not mean slay the fallen gladiator, but mentions that some have even attempted to make the argument that the downward thumb could mean mercy as it symbolized the victorious gladiator placing his weapon down .
Where Did We Get the Thumb Gesture?
Despite the great diversity and controversy over the gestures and position of the thumb, some historians have come to a consensus that the gesture for death was most likely the spectator extending their thumb and pointing it at their breast to symbolize the victorious gladiator thrusting his sword into his opponent’s heart . Corbeill uses Quintilian’s use of the phrase averso pollice  which describes the thumb being pointed at an object in accordance with the phrase infesto pollice, or hostile thumb, to support his argument that a hostile gesture symbolized by a thrusting motion towards the heart was to signify that the fallen gladiator was to be slain. However, despite the small number of historians in agreement, some historians still refute this idea, such as Edwin Post who offers a rather reasonable explanation of why the gestures were most likely not done with fingers. Post argues that because of the large structures that the games were held in, especially the Flavian Amphitheater, and the enormous crowds that attended the games, a gladiator would not be able to see a hand gesture from his position at the bottom of the arena, let alone be able to distinguish which way a spectator’s thumb was pointing. Post also mentions that the Romans were very superstitious people and would not point their thumb at their breast to symbolize a sword being thrust into a heart because they would be pantomiming their own death . Instead, Post offers the argument that the spectators would simply yell and chant phrases that had to do with killing the loser, which correlates with the work of Martial who records spectators chanting their condemnations onto the wounded gladiator and instructing the victor to finish his work .
The gesture of mercy is as ambiguous as the one for condemnation, however, it is generally agreed among historians that it was not the classic gesture of pointing a thumb upward as shown in popular culture. A number of historians agree that a clenched fist, with the thumb either pressed against the other fingers or hidden within the fist, was offered in support of mercy for the defeated gladiator . These gestures have some possible validity with the reasoning that the thumb symbolizes power or the “hostile thumb” symbolizes malicious intent so they should be hidden when offering mercy. Another explanation for the merciful gesture is that the thumb and forefinger are joined together , and the logic of the thumb alone symbolizing power or hostile intent can also be applied since the thumb is accompanied by a finger, possibly representing a sword being placed back into a scabbard. However, both of these possible gestures fall victim to Post’s argument that a simple hand gesture would be nearly impossible for the gladiators to see. Post offers another possible gesture that is rather popular among some historians. With his knowledge of Martial and his reasonable explanation of the poor visibility of the gladiators in the enormous arenas, Post argues that spectators waved cloths or handkerchiefs to signify their wish for mercy. Based on Martial's work that mentions the use of handkerchiefs , other historians mentioning the same , and Post's argument and explanation the use of handkerchiefs or cloths seem to be the most probable gestured used to signify mercy and spare a wounded gladiators life.
Fate of the Thumb is Undecided
In conclusion, due to the lack of definite evidence from ancient Rome historians are left with the controversial problem of differing opinions, explanations, and even evidence that prove to be problematic in determining how the spectators at gladiatorial games decided the fate of a defeated gladiator. Some historians offer very persuasive reasoning in favor of certain gestures such as the ability of the gladiator to see the gestures to the symbolism, mythology, and superstition of those attending the games. Even the ancient sources differ in their explanation of the fate of gladiators. Therefore modern historians are bound to find problems in the field of Roman entertainment, and are left to choose which sources they believe are the most reliable as well as form opinions of their own. The modern world may never have a definite understanding of just how a defeated gladiator was either pardoned or condemned, but are left with differing evidence and explanations.

 Corbeill’s article “Thumbs in Ancient Rome: “Pollex” as Index” also makes note that until the twentieth century many societies, including ancient ones, regarded an upward thumb as a gesture of disapproval or insult while a downward thumb was one of approval.

Yes, Jean Léon Gérôme's "Pollice Verso" is a 19th century painting which shows the artist's imagination of the events,but it does have some historical truth, such as the Vestal Virgins sitting in seats of honor at the games. Also I use it in the article to show that people don't actually know which pointed thumb meant mercy or death. As I mentioned, Gerome's biography indicated that he might have believed that a downward thumb meant mercy, however since it is a work of art it is up to interpretation by the viewer as well as historians trying to figure out the thumb debate.

the pic of the vigens is an 18 century painting ! and no historical truth ,just the artists imagening of the horrow of the imagening scene .

Yves, I am glad you liked this. Gladiators are very interesting especially considering they started as a ceremony during a funeral and soon became the prime entertainment of Rome. Also interesting is their lives, like you said most were miserable but we do have evidence that some gladiators volunteered for this profession, some became widely renowned celebrities and some slaves even won their freedom. Lastly, the most interesting to me is the fact that these fights and games were not always to the death. In fact most were determined by the first to draw blood, wound, disarm, or otherwise beat their opponent without killing them. Nero is actually criticized for not having enough gladiators be killed in his games!

Very interesting. It appears that the downward thumb might be a sign of mercy. But on the other hand....hmmm. I am actually quite baffled. My guess is that the gladiator listened to the jeers of the people and went from there.
Either way, what a miserable life. I've read about gladiators. 99.9 % of them had wretched lives. However, some of them were popular with women----at least.
Great hub. I found it fascinating, truth be told.
