There were many different types of gladiators in ancient Rome. Some of the first gladiators had been prisoners of war, and so some of the earliest types of gladiators were experienced fighters; Gauls, Samnites, and Thraeces (Thracians) used their native weapons and armor. Different gladiator types specialized in specific weapons and fighting techniques. Combatants were usually pitted against opponents with different, but more or less equivalent equipment, for the sake of a fair and balanced contest. Most gladiators only fought others from within the same school or ludus, but sometimes specific gladiators could be requested to fight one from another ludus.

Elite gladiators wore high-quality decorative armour for the pre-game parade (pompa). Julius Caesar's gladiators wore silver armour, Domitian's wore golden armour, and Nero's armour decorated with carved amber. Peacock feathers were used for plumes while tunics and loincloths had patterns in gold thread. For the fighting, functional combat armour was used; this too could be elaborately decorated. Some artistic sources, such as reliefs and mosaics, show gladiators with a various number of tassels hanging from one arm or leg. It has been speculated that they were a form of "scorecard" to show the number of fights a gladiator had won.Stephen Wisdom Gladiators 100 BC-AD 200 Osprey Publishing, 2001 Pg 28–29 Contests were managed by arena referees, and were fought under strict rules and etiquette.Gladiators fought by the book New Scientist February 23, 2006Head injuries of Roman gladiators Forensic Science International Volume 160, Issue 2, Pages 207-216 July 13, 2006Roman gladiators were fat vegetarians ABC Science April 5, 2004

Combat was probably accompanied by music, whose tempo might have varied to match that of the combat. Typical instruments were a long straight trumpet (tuba), a large curved brass instrument (lituus), and a water organ (organum). During the Imperial period, the games might be preceded by a mimus, a form of comedy show. An image from Pompeii shows a "flute-playing bear" (Ursus tibicen) and a "horn-blowing chicken" (Pullus cornicen), that may have been part of such a mimus.Stephen Wisdom, Angus McBride, Gladiators: 100 BC - AD 200, Oxford, United Kingdom, Osprey. Author's sketch and note, p. 18.

Gladiator types The following list includes gladiators as typed by fighting style and equipment, general terms for gladiators, fighters associated with gladiatorial spectacles who were not strictly gladiators, and personnel associated with training or presentation.

Andabata A "blindfolded gladiator", or a "gladiator who fought blind". Cicero jokingly refers to andabata in a letter to his friend Trebatius Testa, who was stationed in Gaul. The passage associates the andabata loosely with essedarii, chariot fighters.Cicero, Ad familiares 7.10.2 (=95), as cited by Piganiol, “Les trinci gauloises." The word is extremely rare in classical sources, and of doubtful etymology; Delamarre suggests it as a Latinised borrowing from Gaulish.cf the entry for andabata in the Oxford Latin Dictionary, and Xavier Delamarre's entry on andabata, in Dictionnaire de la langue gauloise (Éditions Errance, 2003), p. 46.

Arbelas The arbelas as gladiator type is mentioned only in the Oneirocritica of Artemidorus, which discusses dream-symbols and their significance in dream interpretation. It may be related to the Greek word arbelos (ἄρβηλος), a cobbler's semicircular blade used to cut leather.

Bestiarius The bestiarius was a beast-fighter. See also Damnatio ad bestias.

Bustuarius

Bustuarius was a "tomb fighter," from bustum, "tomb", a generalised reference to the association of gladiatorial combat with funeral games (munera). Servius notes that it had once been "the custom to put captives to death at the graves of strong men, which later seemed a bit cruel, so it was decided to have gladiators fight at the tombs."Alison Futrell, Blood in the Arena: The Spectacle of Roman Power (University of Texas Press, 1997), p. 34. Even among gladiators, it was an unflattering term: Cicero used it to liken the morals of his enemy Clodius to those of the very lowest gladiator class.Kyle, Donald G., Sport and Spectacle in the Ancient World, Blackwell Publishing, 2007. p. 273

Cestus The cestus was a fist-fighter or boxer who wore the cestus, a cross between a boxing glove and a heavy-duty type of knuckleduster, but otherwise had no armour.

Crupellarius The Roman historian Tacitus describes a Gaulish contingent of trainee gladiators as crupellarii, equipped "after the national fashion" of Gallia Lugdunensis under Julius Sacrovir, during the Aeduian revolt of AD 21 against Rome. Tacitus has them "encased in the continuous shell of iron usual in the country", labouring under its weight, unable to fight effectively, rapidly tiring and soon dispatched by regular Roman troops. Tacitus' source could refer to a heavily armoured Roman "Gallus" type, which by Tacitus' own time had been developed and renamed as the murmillo.Book III, 43, 46 in The Annals of Tacitus, Loeb, 1931 For possible misidentification, see note 8: "Since the Gauls despised body-armour, the phrase must refer only to the conventional equipment of the "Gallus" (murmillo)"

Dimachaerus The dimachaerus (Greek διμάχαιρος, "bearing two knives") used a sword in each hand.Marcus Junkelmann, 'Familia Gladiatoria: "The Heroes of the Amphitheatre"' in The Power of Spectacle in Ancient Rome: Gladiators and Caesars, ed. by Eckart Köhne and Cornelia Ewigleben (Berkeley and Los Angeles, 2000), p. 63

Eques Eques, plural equites, was a member of the middle-to-higher class of citizen-aristocracy, forbidden to take part in the games. Eques is also the regular Latin word for a horseman or cavalryman and a gladiator type. Early forms of the eques gladiator were lightly armed, with sword or spear. They had scale armour; a medium-sized round cavalry shield (parma equestris); and a brimmed helmet with two decorative feathers and no crest. Later forms also had greaves to protect their legs, a manica on their right arm and sleeveless, belted tunics. Generally, they fought only other equites.Junkelmann 2000, pp. 37 and 47-48

Essedarius The essedarius (from the Latin word for a Celtic war-chariot, essedum) was likely first brought to Rome from Britain by Julius Caesar. Essedarii appear as arena-fighters in many inscriptions after the 1st century AD, apparently pitted against opponents of their own type. It is not known whether the essedarius entered the arena in his chariot, then dismounted and fought on foot, or fought while in the chariot. Some, or possibly all essedarii were driven by charioteers. No relevant pictorial evidence survives.

Gallus Literally a "Gaul"; either a prisoner of war, as in the earliest forms of munus, or else a gladiator equipped with Gaulish arms and armour, who fought in what Romans would have recognised as a "Gaulish style". Probably a heavyweight, and heavily armoured, the Gallus seems to have been replaced by, or perhaps transformed into, the murmillo, soon after Gaul's absorption as a Roman province.

Gladiatrix

This refers to a female gladiator of any type. They were very rare, and their existence is poorly documented. They appear occasionally around the end of the Roman Republic and were banned by the emperor Septimius Severus by AD 200. The earliest known use of "gladiatrix" is post-Classical, in a 4th-century gloss of Juvenal's comments on the beast-hunter Mevia.McCullough, Anna., “Female Gladiators in the Roman Empire”, in: Budin & Turfa (eds), Women in Antiquity: Real Women across the Ancient World, Routledge (2016), p. 958

Hoplomachus The hoplomachus (Romanised Greek for "armed fighter", Latin plural hoplomachii) wore quilted, trouser-like leg wrappings, loincloth, a belt, a pair of long shin-guards or greaves, an arm guard (manica) on the sword-arm, and a brimmed helmet that could be adorned with a plume of feathers on top and a single feather on each side. He was equipped with a gladius and a very small, round shield. He also carried a spear, which he would have to cast at his opponent before closing for hand-to-hand combat. The hoplomachi were paired against the myrmillones or Thraeces. They may have developed out of the earlier '"Samnite" type after it became impolitic to use the names of now-allied peoples.Junkelmann 2000, pp. 52-53

Laquearius The laquearius may have been a kind of Paegniarius, or a type of retiarius who tried to catch his adversaries with a lasso (laqueus) instead of a net.

Murmillo The murmillo (plural murmillones) or myrmillo wore a helmet with a stylised fish on the crest (the mormylos or sea fish), as well as an arm guard (manica), a loincloth and belt, a gaiter on his right leg, thick wrappings covering the tops of his feet, and a very short greave with an indentation for the padding at the top of the feet. They are heavily armoured gladiators: the murmillo carried a gladius (64–81 cm long) and a tall, oblong shield in the legionary style. Murmillones typically fought a thraex, but occasionally the similar hoplomachus.Junkelmann 2000, pp. 48-51

Parmularius A parmularius (pl parmularii) was any gladiator who carried a parmula (small shield), in contrast to a scutarius, who bore a larger shield (scutum). To compensate for this reduced protection, parmularii were usually equipped with two greaves, rather than the single greave of a scutarius. The thraex would have been named as parmularii.

Provocator In the late Republican and early Imperial era, the armament of a provocator ("challenger") mirrored legionary armature. In the later Imperial period, their armament ceased to reflect its military origins, and changes in armament followed changes in arena fashion only. Provocatores have been shown wearing a loincloth, a belt, a long greave on the left leg, a manica on the lower right arm, and a visored helmet without brim or crest, but with a feather on each side. They were the only gladiators protected by a breastplate (cardiophylax) which is usually rectangular, later often crescent-shaped. They usually fought with a tall, rectangular shield and the gladius, but the use of the spatha is also attested. They were paired only against other provocatores.Junkelmann 2000, pp. 37 and 57-59. See the headstone of Anicetus for a provocator with spatha.

Retiarius The retiarius ("net fighter") developed in the early Augustan period. He carried a trident and a net, equipment styled on that of a fisherman. The retiarius wore a loincloth held in place by a wide belt and a larger arm guard (manica) extending to the shoulder and left side of the chest. He fought without the protection of a helmet. Occasionally a metal shoulder shield (galerus) was added to protect the neck and lower face. A tombstone found in Romania shows a retiarius holding a dagger with four spikes (each at the corner of a square guard) instead of the usual sharp dagger. A variation to the normal combat was a retiarius facing two secutores at the same time. The retiarius stood on a bridge or raised platform with stairs and had a pile of fist-sized stones to throw at his adversaries. While the retiarius tried to keep them at bay, the secutores tried to scale the structure to attack him. The platform, called a pons (bridge), may have been constructed over water.Junkelmann 60–61. Retiarii usually fought secutores but sometimes fought myrmillones.Junkelmann 2000, pp. 59-61 There was an effeminate class of gladiator who fought as a retiarius tunicatus. They wore tunics to distinguish them from the usual retiarius, and were looked on as a social class even lower than infamia.F. R. D. Goodyear The Classical Papers of A. E. Housman:, Volume 2; Volumes 1897-1914 Cambridge University Press 2004 Pg 621 - 622"The Retiarius Tunicatus of Suetonius, Juvenal, and Petronius" (1989) by Steven M. Cerutti and L. Richardson, Jr. The American Journal of Philology, 110, P589-594
