In ancient Roman religion and myth, Mars (Latin: Mārs, [maːrs]) was the god of war and also an agricultural guardian, a combination characteristic of early Rome. He was second in importance only to Jupiter and he was the most prominent of the military gods in the religion of the Roman army. Most of his festivals were held in March, the month named for him (Latin Martius), and in October, which began the season for military campaigning and ended the season for farming.
Under the influence of Greek culture, Mars was identified with the Greek god Ares, whose myths were reinterpreted in Roman literature and art under the name of Mars. But the character and dignity of Mars differed in fundamental ways from that of his Greek counterpart, who is often treated with contempt and revulsion in Greek literature. Mars was a part of the Archaic Triad along with Jupiter and Quirinus, the latter of whom as a guardian of the Roman people had no Greek equivalent. Mars' altar in the Campus Martius, the area of Rome that took its name from him, was supposed to have been dedicated by Numa, the peace-loving semi-legendary second king of Rome. Although the center of Mars' worship was originally located outside the sacred boundary of Rome (pomerium), Augustus made the god a renewed focus of Roman religion by establishing the Temple of Mars Ultor in his new forum.
Although Ares was viewed primarily as a destructive and destabilizing force, Mars represented military power as a way to secure peace, and was a father (pater) of the Roman people. In the mythic genealogy and founding myths of Rome, Mars was the father of Romulus and Remus with Rhea Silvia. His love affair with Venus symbolically reconciled the two different traditions of Rome's founding; Venus was the divine mother of the hero Aeneas, celebrated as the Trojan refugee who "founded" Rome several generations before Romulus laid out the city walls.
The importance of Mars in establishing religious and cultural identity within the Roman Empire is indicated by the vast number of inscriptions identifying him with a local deity, particularly in the Western provinces.

Although Ares was the son of Zeus and Hera, Mars was the son of Juno alone. Jupiter had usurped the mother's function when he gave birth to Minerva directly from his forehead (or mind); to restore the balance, Juno sought the advice of the goddess Flora on how to do the same. Flora obtained a magic flower (Latin flos, plural flores, a masculine word) and tested it on a heifer who became fecund at once. She then plucked a flower ritually using her thumb, touched Juno's belly, and impregnated her. Juno withdrew to Thrace and the shore of Marmara for the birth.
Ovid tells this story in the Fasti, his long-form poetic work on the Roman calendar. It may explain why the Matronalia, a festival celebrated by married women in honor of Juno as a goddess of childbirth, occurred on the first day of Mars' month, which is also marked on a calendar from late antiquity as the birthday of Mars. In the earliest Roman calendar, March was the first month, and the god would have been born with the new year. Ovid is the only source for the story. He may be presenting a literary myth of his own invention, or an otherwise unknown archaic Italic tradition; either way, in choosing to include the story, he emphasizes that Mars was connected to plant life and was not alienated from female nurture.
The consort of Mars was Nerio or Nerine, "Valor." She represents the vital force (vis), power (potentia) and majesty (maiestas) of Mars. Her name was regarded as Sabine in origin and is equivalent to Latin virtus, "manly virtue" (from vir, "man"). In the early 3rd century BC, the comic playwright Plautus has a reference to Mars greeting Nerio, his wife. A source from late antiquity says that Mars and Nerine were celebrated together at a festival held on March 23. In the later Roman Empire, Nerine came to be identified with Minerva.
Nerio probably originates as a divine personification of Mars' power, as such abstractions in Latin are generally feminine. Her name appears with that of Mars in an archaic prayer invoking a series of abstract qualities, each paired with the name of a deity. The influence of Greek mythology and its anthropomorphic gods may have caused Roman writers to treat these pairs as "marriages."
Venus and Mars
The union of Venus and Mars held greater appeal for poets and philosophers, and the couple were a frequent subject of art. In Greek myth, the adultery of Ares and Aphrodite had been exposed to ridicule when her husband Hephaestus (whose Roman equivalent was Vulcan) caught them in the act by means of a magical snare. Although not originally part of the Roman tradition, in 217 BC Venus and Mars were presented as a complementary pair in the lectisternium, a public banquet at which images of twelve major gods of the Roman state were presented on couches as if present and participating.
Scenes of Venus and Mars in Roman art often ignore the adulterous implications of their union, and take pleasure in the good-looking couple attended by Cupid or multiple Loves (amores). Some scenes may imply marriage, and the relationship was romanticized in funerary or domestic art in which husbands and wives had themselves portrayed as the passionate divine couple.
The uniting of deities representing Love and War lent itself to allegory, especially since the lovers were the parents of Harmonia. The Renaissance philosopher Marsilio Ficino notes that "only Venus dominates Mars, and he never dominates her". In ancient Roman and Renaissance art, Mars is often shown disarmed and relaxed, or even sleeping, but the extramarital nature of their affair can also suggest that this peace is impermanent.
Virility as a kind of life force (vis) or virtue (virtus) is an essential characteristic of Mars. As an agricultural guardian, he directs his energies toward creating conditions that allow crops to grow, which may include warding off hostile forces of nature. As an embodiment of masculine aggression, he is the force that drives wars – but ideally, war that delivers a secure peace.
The priesthood of the Arval Brothers called on Mars to drive off "rust" (lues), with its double meaning of wheat fungus and the red oxides that affect metal, a threat to both iron farm implements and weaponry. In the surviving text of their hymn, the Arval Brothers invoked Mars as ferus, "savage" or "feral" like a wild animal.
Mars' potential for savagery is expressed in his obscure connections to the wild woodlands, and he may even have originated as a god of the wild, beyond the boundaries set by humans, and thus a force to be propitiated. In his book on farming, Cato invokes Mars Silvanus for a ritual to be carried out in silva, in the woods, an uncultivated place that if not held within bounds can threaten to overtake the fields needed for crops. Mars' character as an agricultural god may derive solely from his role as a defender and protector, or may be inseparable from his warrior nature, as the leaping of his armed priests the Salii was meant to quicken the growth of crops.
The wild animals most sacred to Mars were the woodpecker, the wolf, and the bear, which in the natural lore of the Romans were said always to inhabit the same foothills and woodlands.
Plutarch notes that the woodpecker (picus) is sacred to Mars because "it is a courageous and spirited bird and has a beak so strong that it can overturn oaks by pecking them until it has reached the inmost part of the tree." As the beak of the picus Martius contained the god's power to ward off harm, it was carried as a magic charm to prevent bee stings and leech bites. The bird of Mars also guarded a woodland herb (paeonia) used for treatment of the digestive or female reproductive systems; those who sought to harvest it were advised to do so by night, lest the woodpecker jab out their eyes. The picus Martius seems to have been a particular species, but authorities differ on which one: perhaps Picus viridis or Dryocopus martius.
The woodpecker was revered by the Latin peoples, who abstained from eating its flesh. It was one of the most important birds in Roman and Italic augury, the practice of reading the will of the gods through watching the sky for signs. The mythological figure named Picus had powers of augury that he retained when he was transformed into a woodpecker; in one tradition, Picus was the son of Mars. The Umbrian cognate peiqu also means "woodpecker," and the Italic Picenes were supposed to have derived their name from the picus who served as their guide animal during a ritual migration (ver sacrum) undertaken as a rite of Mars. In the territory of the Aequi, another Italic people, Mars had an oracle of great antiquity where the prophecies were supposed to be spoken by a woodpecker perched on a wooden column.
Mars' association with the wolf is familiar from what may be the most famous of Roman myths, the story of how a she-wolf (lupa) suckled his infant sons when they were exposed by order of their grandfather, Numitor, who feared that they would take back the kingship he had usurped. The woodpecker also brought nourishment to the twins.
The wolf appears elsewhere in Roman art and literature in masculine form as the animal of Mars. A statue group that stood along the Appian Way showed Mars in the company of wolves. At the Battle of Sentinum in 295 BC, the appearance of the wolf of Mars (Martius lupus) was a sign that Roman victory was to come.
In Roman Gaul, the goose was associated with the Celtic forms of Mars, and archaeologists have found geese buried alongside warriors in graves. The goose was considered a bellicose animal because it is easily provoked to aggression.
Ancient Greek and Roman religion distinguished between animals that were sacred to a deity and those that were prescribed as the correct sacrificial offerings for the god. Wild animals might be viewed as already belonging to the god to whom they were sacred, or at least not owned by human beings and therefore not theirs to give. Since sacrificial meat was eaten at a banquet after the gods received their portion – mainly the entrails (exta) — it follows that the animals sacrificed were most often, though not always, domestic animals normally part of the Roman diet. Gods often received castrated male animals as sacrifices, and the goddesses female victims; Mars, however, regularly received intact males. Mars did receive oxen under a few of his cult titles, such as Mars Grabovius, but the usual offering was the bull, singly, in multiples, or in combination with other animals.
The two most distinctive animal sacrifices made to Mars were the suovetaurilia, a triple offering of a pig (sus), ram (ovis) and bull (taurus), and the October Horse, the only horse sacrifice known to have been carried out in ancient Rome and a rare instance of a victim the Romans considered inedible.
Temples and topography in Rome
The earliest center in Rome for cultivating Mars as a deity was the Altar of Mars (Ara Martis) in the Campus Martius ("Field of Mars") outside the sacred boundary of Rome (pomerium). The Romans thought that this altar had been established by the semi-legendary Numa Pompilius, the peace-loving successor of Romulus. According to Roman tradition, the Campus Martius had been consecrated to Mars by their ancestors to serve as horse pasturage and an equestrian training ground for youths. During the Roman Republic (509–27 BC), the Campus was a largely open expanse. No temple was built at the altar, but from 193 BC a covered walkway connected it to the Porta Fontinalis, near the office and archives of the Roman censors. Newly elected censors placed their curule chairs by the altar, and when they had finished conducting the census, the citizens were collectively purified with a suovetaurilia there. A frieze from the so-called "Altar" of Domitius Ahenobarbus is thought to depict the census, and may show Mars himself standing by the altar as the procession of victims advances.
The main Temple of Mars (Aedes Martis) in the Republican period also lay outside the sacred boundary and was devoted to the god's warrior aspect. It was built to fulfill a vow (votum) made by a Titus Quinctius in 388 BC during the Gallic siege of Rome. The founding day (dies natalis) was commemorated on June 1, and the temple is attested by several inscriptions and literary sources. The sculpture group of Mars and the wolves was displayed there. Soldiers sometimes assembled at the temple before heading off to war, and it was the point of departure for a major parade of Roman cavalry held annually on July 15.
The Campus Martius continued to provide venues for equestrian events such as chariot racing during the Imperial period, but under the first emperor Augustus it underwent a major program of urban renewal, marked by monumental architecture. The Altar of Augustan Peace (Ara Pacis Augustae) was located there, as was the Obelisk of Montecitorio, imported from Egypt to form the pointer (gnomon) of the Solarium Augusti, a giant sundial. With its public gardens, the Campus became one of the most attractive places in the city to visit.
Augustus chose the Campus Martius as the site of his new Temple to Mars Ultor, a manifestation of Mars he cultivated as the avenger (ultor) of the murder of Julius Caesar and of the military disaster suffered at the Battle of Carrhae. When the legionary standards lost to the Parthians were recovered, they were housed in the new temple. The date of the temple's dedication on May 12 was aligned with the heliacal setting of the constellation Scorpio, the house of war. The date continued to be marked with circus games as late as the mid-4th century AD.
Iconography and Symbol
In Roman art, Mars is depicted as either bearded and mature, or young and clean-shaven. Even nude or seminude, he often wears a helmet or carries a spear as emblems of his warrior nature. Mars was among the deities to appear on the earliest Roman coinage in the late 4th and early 3rd century BC.
On the Altar of Peace (Ara Pacis), built in the last years of the 1st century BC, Mars is a mature man with a "handsome, classicizing" face, and a short curly beard and moustache. His helmet is a plumed neo-Attic-type. He wears a military cloak (paludamentum) and a cuirass ornamented with a gorgoneion. Although the relief is somewhat damaged at this spot, he appears to hold a spear garlanded in laurel, symbolizing a peace that is won by military victory. The 1st-century statue of Mars found in the Forum of Nerva (pictured at top) is similar. In this guise, Mars is presented as the dignified ancestor of the Roman people. The panel of the Ara Pacis on which he appears would have faced the Campus Martius, reminding viewers that Mars was the god whose altar Numa established there, that is, the god of Rome's oldest civic and military institutions.
Particularly in works of art influenced by the Greek tradition, Mars may be portrayed in a manner that resembles Ares, youthful, beardless, and often nude. In the Renaissance, Mars' nudity was thought to represent his lack of fear in facing danger.
The spear of Mars
The spear is the instrument of Mars in the same way that Jupiter wields the lightning bolt, Neptune the trident, and Saturn the scythe or sickle. A relic or fetish called the spear of Mars was kept in a sacrarium at the Regia, the former residence of the Kings of Rome. The spear was said to move, tremble or vibrate at impending war or other danger to the state, as was reported to occur before the assassination of Julius Caesar. When Mars is pictured as a peace-bringer, his spear is wreathed with laurel or other vegetation, as on the Ara Pacis or a coin of Aemilianus.
The high priest of Mars in Roman public religion was the Flamen Martialis, who was one of the three major priests in the fifteen-member college of flamens. Mars was also served by the Salii, a twelve-member priesthood of patrician youths who dressed as archaic warriors and danced in procession around the city in March. Both priesthoods extend to the earliest periods of Roman history, and patrician birth was required.
Festivals and rituals
The festivals of Mars cluster in his namesake month of March (Latin: Martius), with a few observances in October, the beginning and end of the season for military campaigning and agriculture. Festivals with horse racing took place in the Campus Martius. Some festivals in March retained characteristics of new year festivals, since Martius was originally the first month of the Roman calendar.
- February 27: Equirria, involving chariot or horse races;
- March 1: Mars' dies natalis ("birthday"), a feria also sacred to his mother Juno;
- March 14: a second Equirria, again with chariot races;
- March 14 or 15: Mamuralia, a new year festival when a figure called Mamurius Veturius (perhaps the "old Mars" of the old year) is driven out;
- March 17: an Agonalia or Agonium Martiale, an obscure type of observance held at other times for various deities;
- March 23: Tubilustrium, a purification of the deploying army March 23;
- October 15: the ritual of the October Horse, with a chariot race and Rome's only known horse sacrifice;
- October 19: Armilustrium ("purification of arms").
Mars was also honored by chariot races at the Robigalia and Consualia, though these festivals are not primarily dedicated to him. From 217 BC onward, Mars was among the gods honored at the lectisternium, a banquet given for deities who were present as images.
Roman hymns (carmina) are rarely preserved, but Mars is invoked in two. The Arval Brothers, or "Brothers of the Fields," chanted a hymn to Mars while performing their three-step dance. The Carmen Saliare was sung by Mars' priests the Salii while they moved twelve sacred shields (ancilia) throughout the city in a procession. In the 1st century AD, Quintilian remarks that the language of the Salian hymn was so archaic that it was no longer fully understood.
Name and cult epithets
The word Mārs (genitive Mārtis), which in Old Latin and poetic usage also appears as Māvors (Māvortis), is cognate with Oscan Māmers (Māmertos). The Old Latin form was believed to derive from an Italic *Māworts, but can also be explained as deriving from Maris, the name of an Etruscan child-god; scholars have varying views on whether the two gods are related, and if so how. Latin adjectives from the name of Mars are martius and martialis, from which derive English "martial" (as in "martial arts" or "martial law") and personal names such as "Martin".
Mars also gave his name to the third month in the Roman calendar, Martius, from which English "March" derives. In the most ancient Roman calendar, Martius was the first month. The planet Mars was named for him, and in some allegorical and philosophical writings, the planet and the god are endowed with shared characteristics. In many languages, Tuesday is named for the planet Mars or the god of war: In Latin, martis dies ("Mars's Day"), survived in Romance languages as martes (Spanish), mardi (French), martedi (Italian), marţi (Romanian), and dimarts (Catalan). In Irish (Gaelic), the day is An Mháirt. The English word Tuesday derives from Old English "Tiwesdæg" and means "Tiw's Day", Tiw being the Old English form of the Proto-Germanic war god *Tîwaz, or Týr in Norse.
In Roman religion
In Classical Roman religion, Mars was invoked under several titles, and the first Roman emperor Augustus thoroughly integrated Mars into Imperial cult. The 4th-century Latin historian Ammianus Marcellinus treats Mars as one of several classical Roman deities who remained "cultic realities" up to his own time. Mars, and specifically Mars Ultor, was among the gods who received sacrifices from Julian, the only emperor to reject Christianity after the conversion of Constantine I. In 363 AD, in preparation for the Siege of Ctesiphon, Julian sacrificed ten "very fine" bulls to Mars Ultor. The tenth bull violated ritual protocol by attempting to break free, and when killed and examined, produced ill omens, among the many that were read at the end of Julian's reign. As represented by Ammianus, Julian swore never to make sacrifice to Mars again—a vow kept with his death a month later.
Gradivus was one of the gods by whom a general or soldiers might swear an oath to be valorous in battle. His temple outside the Porta Capena was where armies gathered. The archaic priesthood of Mars Gradivus was the Salii, the "leaping priests" who danced ritually in armor as a prelude to war. His cult title is most often taken to mean "the Strider" or "the Marching God," from gradus, "step, march."
The poet Statius addresses him as "the most implacable of the gods," but Valerius Maximus concludes his history by invoking Mars Gradivus as "author and support of the name 'Roman'": Gradivus is asked – along with Capitoline Jupiter and Vesta, as the keeper of Rome's perpetual flame – to "guard, preserve, and protect" the state of Rome, the peace, and the princeps (the emperor Tiberius at the time).
Mars Quirinus was the protector of the Quirites ("citizens" or "civilians") as divided into curiae (citizen assemblies), whose oaths were required to make a treaty. As a guarantor of treaties, Mars Quirinus is thus a god of peace: "When he rampages, Mars is called Gradivus, but when he's at peace Quirinus."
The deified Romulus was identified with Mars Quirinus. In the Capitoline Triad of Jupiter, Mars, and Quirinus, however, Mars and Quirinus were two separate deities, though not perhaps in origin. Each of the three had his own flamen (specialized priest), but the functions of the Flamen Martialis and Flamen Quirinalis are hard to distinguish.
Mars is invoked as Grabovius in the Iguvine Tablets, bronze tablets written in Umbrian that record ritual protocols for carrying out public ceremonies on behalf of the city and community of Iguvium. The same title is given to Jupiter and to the Umbrian deity Vofionus. This triad has been compared to the Archaic Triad, with Vofionus equivalent to Quirinus. Tables I and VI describe a complex ritual that took place at the three gates of the city. After the auspices were taken, two groups of three victims were sacrificed at each gate. Mars Grabovius received three oxen.
"Father Mars" or "Mars the Father" is the form in which the god is invoked in the agricultural prayer of Cato, and he appears with this title in several other literary texts and inscriptions. Mars Pater is among the several gods invoked in the ritual of devotio, by means of which a general sacrificed himself and the lives of the enemy to secure a Roman victory.
Father Mars is the regular recipient of the suovetaurilia, the sacrifice of a pig (sus), ram (ovis) and bull (taurus), or often a bull alone. To Mars Pater other epithets were sometimes appended, such as Mars Pater Victor ("Father Mars the Victorious"), to whom the Roman army sacrificed a bull on March 1.
Although pater and mater were fairly common as honorifics for a deity, any special claim for Mars as father of the Roman people lies in the mythic genealogy that makes him the divine father of Romulus and Remus.
In the section of his farming book that offers recipes and medical preparations, Cato describes a votum to promote the health of cattle:
Make an offering to Mars Silvanus in the forest (in silva) during the daytime for each head of cattle: 3 pounds of meal, 4½ pounds of bacon, 4½ pounds of meat, and 3 pints of wine. You may place the viands in one vessel, and the wine likewise in one vessel. Either a slave or a free man may make this offering. After the ceremony is over, consume the offering on the spot at once. A woman may not take part in this offering or see how it is performed. You may vow the vow every year if you wish.
That Mars Silvanus is a single entity has been doubted. Invocations of deities are often list-like, without connecting words, and the phrase should perhaps be understood as "Mars and Silvanus". Women were explicitly excluded from some cult practices of Silvanus, but not necessarily of Mars. William Warde Fowler, however, thought that the wild god of the wood Silvanus may have been "an emanation or offshoot" of Mars.
Augustus created the cult of "Mars the Avenger" to mark two occasions: his defeat of the assassins of Caesar at Philippi in 42 BC, and the negotiated return of the Roman battle standards that had been lost to the Parthians at the Battle of Carrhae in 53 BC. The god is depicted wearing a cuirass and helmet and standing in a "martial pose," leaning on a lance he holds in his right hand. He holds a shield in his left hand. The goddess Ultio, a divine personification of vengeance, had an altar and golden statue in his temple.
The Temple of Mars Ultor, dedicated in 2 BC in the center of the Forum of Augustus, gave the god a new place of honor. Some rituals previously conducted within the cult of Capitoline Jupiter were transferred to the new temple, which became the point of departure for magistrates as they left for military campaigns abroad. Augustus required the Senate to meet at the temple when deliberating questions of war and peace. The temple also became the site at which sacrifice was made to conclude the rite of passage of young men assuming the toga virilis ("man's toga") around age 14.
On various Imperial holidays, Mars Ultor was the first god to receive a sacrifice, followed by the Genius of the emperor. An inscription from the 2nd century records a vow to offer Mars Ultor a bull with gilded horns.
Augustus or Augusta was appended far and wide, "on monuments great and small," to the name of gods or goddesses, including Mars. The honorific marks the affiliation of a deity with Imperial cult. In Hispania, many of the statues and dedications to Mars Augustus were presented by members of the priesthood or sodality called the Sodales Augustales. These vows (vota) were usually fulfilled within a sanctuary of Imperial cult, or in a temple or precinct (templum) consecrated specifically to Mars. As with other deities invoked as Augustus, altars to Mars Augustus might be set up to further the well-being (salus) of the emperor, but some inscriptions suggest personal devotion. An inscription in the Alps records the gratitude of a slave who dedicated a statue to Mars Augustus as conservator corporis sui, the preserver of his own body, said to have been vowed ex iussu numinis ipsius, "by the order of the numen himself".
Mars Augustus appears in inscriptions at sites throughout the Empire, such as Hispania Baetica, Saguntum, and Emerita (Lusitania) in Roman Spain; Leptis Magna (with a date of 6–7 AD) in present-day Libya; and Sarmizegetusa in the province of Dacia.
In addition to his cult titles at Rome, Mars appears in a large number of inscriptions in the provinces of the Roman Empire, and more rarely in literary texts, identified with a local deity by means of an epithet. Mars appears with great frequency in Gaul among the Continental Celts, as well as in Roman Spain and Britain. In Celtic settings, he is often invoked as a healer. The inscriptions indicate that Mars' ability to dispel the enemy on the battlefield was transferred to the sick person's struggle against illness; healing is expressed in terms of warding off and rescue.
Mars is identified with a number of Celtic deities, some of whom are not attested independently.
- Mars Alator is attested in Roman Britain by an inscription found on an altar at South Shields, and a silver-gilt votive plaque that was part of the Barkway hoard from Hertfordshire. Alator has been interpreted variously as "Huntsman" or "Cherisher".
- Mars Albiorix appears in an inscription from modern-day Sablet, in the province of Gallia Narbonensis. Albiorix probably means "King of the Land" or "King of the World", with the first element related to the geographical name Albion and Middle Welsh elfydd, "world, land".
- Mars Barrex is attested by a single dedicatory inscription found at Carlisle, England. Barrex or Barrecis probably means "Supreme One" (Gaulish barro-, "head").
- Mars Belatucadrus is named in five inscriptions in the area of Hadrian's Wall. The Celtic god Belatucadros, with various spellings, is attested independently in twenty additional inscriptions in northern England.
- Mars Braciaca appears in a single votive inscription at Bakewell, Derbyshire. The Celtic epithet may refer to malt or beer, though intoxication in Greco-Roman religion is associated with Dionysus. A reference in Pliny suggests a connection to Mars' agricultural function, with the Gaulish word bracis referring to a type of wheat; a medieval Latin gloss says it was used to make beer.
- Mars Camulus is found in five inscriptions scattered over a fairly wide geographical area. The Celtic god Camulus appears independently in one votive inscription from Rome.
- Mars Cocidius is found in five inscriptions from northern England. About twenty dedications in all are known for the Celtic god Cocidius, mainly made by Roman military personnel, and confined to northwest Cumbria and along Hadrian's Wall. He is once identified with Silvanus. He is depicted on two votive plaques as a warrior bearing shield and spear, and on an altar as a huntsman accompanied by a dog and stag.
- Mars Condatis occurs in three inscriptions from Roman Britain. The cult title is probably related to the place name Condate, often used in Gaul for settlements at the confluence of rivers. The Celtic god Condatis is thought to have functions pertaining to water and healing.
- Mars Corotiacus is an equestrian Mars attested only on a votive from Martlesham in Suffolk. A bronze statuette depicts him as a cavalryman, armed and riding a horse which tramples a prostrate enemy beneath its hooves.
- Mars Lenus, or more often Lenus Mars, had a major healing cult at the capital of the Treveri (present-day Trier). Among the votives are images of children offering doves. His consort Ancamna is also found with the Celtic god Smertrios.
- Mars Loucetius. The Celtic god Loucetios, Latinized as -ius, appears in nine inscriptions in present-day Germany and France and one in Britain, and in three as Leucetius. The Gaulish and Brythonic theonyms likely derive from Proto-Celtic *louk(k)et-, "bright, shining, flashing," hence also "lightning," alluding to either a Celtic commonplace metaphor between battles and thunderstorms (Old Irish torannchless, the "thunder feat"), or the aura of a divinized hero (the lúan of Cú Chulainn). The name is given as an epithet of Mars. The consort of Mars Loucetius is Nemetona, whose name may be understood as pertaining either to "sacred privilege" or to the sacred grove (nemeton), and who is also identified with the goddess Victoria. At the Romano-British site in Bath, a dedication to Mars Loucetius as part of this divine couple was made by a pilgrim who had come from the continental Treveri of Gallia Belgica to seek healing.
- Mars Medocius Campesium appears on a bronze plaque at a Romano-Celtic temple at Camulodunum (modern Colchester; see Mars Camulus above). The dedication was made between 222 and 235 AD by a self-identified Caledonian, jointly honoring Mars and the Victoria (Victory) of Severus Alexander. A Celto-Latin name Medocius or Medocus is known, and a link between Mars' epithet and the Irish legendary surgeon Miodhach has been conjectured. Campesium may be an error for Campestrium, "of the Campestres", the divinities who oversaw the parade ground, or "of the Compeses" may refer to a local place name or ethnonym.
- Mars Mullo is invoked in two Armorican inscriptions pertaining to Imperial cult. The name of the Celtic god Mullo, which appears in a few additional inscriptions, has been analyzed variously as "mule" and "hill, heap".
- Mars Neton or Neto was a Celtiberian god at Acci (modern Guadix). According to Macrobius, he wore a radiant crown like a sun god, because the passion to act with valor was a kind of heat. He may be connected to Irish Neit.
- Mars Nodens has a possible connection to the Irish mythological figure Nuada Airgetlám. The Celtic god Nodens was also interpreted as equivalent to several other Roman gods, including Mercury and Neptune. The name may have meant "catcher", hence a fisher or hunter.
- Mars Ocelus had an altar dedicated by a junior army officer at Caerwent, and possibly a temple. He may be a local counterpart to Lenus.
- Mars Olloudius was depicted in a relief from Roman Britain without armor, in the guise of a Genius carrying a double cornucopia and holding a libation bowl (patera). Olloudius is found also at Ollioules in southern Gaul.
- Mars Rigisamus is found in two inscriptions, the earliest most likely the one at Avaricum (present-day Bourges, France) in the territory of the Bituriges. At the site of a villa at West Coker, Somerset, he received a bronze plaque votum. The Gaulish element rig- (very common at the end of names as -rix), found in later Celtic languages as rí, is cognate with Latin rex, "king" or more precisely "ruler". Rigisamos is "supreme ruler" or "king of kings".
- Mars Rigonemetis ("King of the Sacred Grove"). A dedication to Rigonemetis and the numen (spirit) of the Emperor inscribed on a stone was discovered at Nettleham (Lincolnshire) in 1961. Rigonemetis is only known from this site, and it seems he may have been a god belonging to the tribe of the Corieltauvi.
- Mars Segomo. "Mars the Victorious" appears among the Celtic Sequani.
- Mars Smertrius. At a site within the territory of the Treveri, Ancamna was the consort of Mars Smertrius.
- Mars Teutates. A fusion of Mars with the Celtic god Teutates (Toutatis).
- Mars Thincsus. A form of Mars invoked at Housesteads Roman Fort at Hadrian's Wall, where his name is linked with two goddesses called the Alaisiagae. Anne Ross associated Thincsus with a sculpture, also from the fort, which shows a god flanked by goddesses and accompanied by a goose – a frequent companion of war gods.
- Mars Visucius. A fusion of Mars with the Celtic god Visucius.
- Mars Vorocius. A Celtic healer-god invoked at the curative spring shrine at Vichy (Allier) as a curer of eye afflictions. On images, the god is depicted as a Celtic warrior.
"Mars Balearicus" is a name used in modern scholarship for small bronze warrior figures from Majorca (one of the Balearic Islands) that are interpreted as representing the local Mars cult. These statuettes have been found within talayotic sanctuaries with extensive evidence of burnt offerings. "Mars" is fashioned as a lean, athletic nude lifting a lance and wearing a helmet, often conical; the genitals are perhaps semi-erect in some examples.
Other bronzes at the sites represent the heads or horns of bulls, but the bones in the ash layers indicate that sheep, goats, and pigs were the sacrificial victims. Bronze horse-hooves were found in one sanctuary. Another site held an imported statue of Imhotep, the legendary Egyptian physician. These sacred precincts were still in active use when the Roman occupation began in 123 BC. They seem to have been astronomically oriented toward the rising or setting of the constellation Centaurus.

Onians connects the name of Mars to the Latin mas, maris, "male" (p. 178), as had Isidore of Seville, saying that the month of March (Martius) was named after Mars "because at that time all living things are stirred toward virility (mas, gen. maris) and to the pleasures of sexual intercourse" (eo tempore cuncta animantia agantur ad marem et ad concumbendi voluptatem): Etymologies 5.33.5, translation by Stephen A.

In pre-modern agricultural societies, encroaching woodland or wild growth was a real threat to the food supply, since clearing land for cultivation required intense manual labor with minimal tools and little or no large-scale machinery. Fowler says of Mars, "As he was not localised either on the farm or in the city, I prefer to think that he was originally conceived as a Power outside the boundary in each case, but for that very reason all the more to be propitiated by the settlers within it" (Religious Experience, p. 142).

- Compare Gradiva. The second-century grammarian Sextus Pompeius Festus offers two other explanations in addition. The name, he says, might also mean the vibration of a spear, for which the Greeks use the word kradainein; others locate the origin of Gradivus in the grass (gramine), because the Grass Crown is the highest military honor; see Carole Newlands, Playing with Time: Ovid and the Fasti (Cornell University Press, 1995), p. 106.

At Aeneid 6.860, Servius further notes: "Quirinus is the Mars who presides over peace and whose cult is maintained within the civilian realm, for the Mars of war has his temple outside that realm." See also Belier, Decayed Gods, p. 92: "The identification of the two gods is a reflection of a social process. The men who till the soil as Quirites in times of peace are identical with the men who defend their country as Milites in times of war."

- Etymologically, Quirinus is *co-uiri-no, "(the god) of the community of men (viri)," and Vofionus is *leudhyo-no, "(the god) of the people": Oliver de Cazanove, "Pre-Roman Italy, Before and Under the Romans," in A Companion to Roman Religion (Blackwell, 2007), p. 49. It has also been argued that Vofionus corresponds to Janus, because an entry in Sextus Pompeius Festus (204, edition of Lindsay) indicates there was a Roman triad of Jupiter, Mars, and Janus, each having quirinus as a title; C.

- For instance, during the Republic, the dictator was charged with the ritual clavi figendi causa, driving a nail into the wall of the Capitoline temple. According to Cassius Dio (55.10.4, as cited by Lipka, Roman Gods, p. 108), this duty was transferred to a censor under Augustus, and the ritual moved to the Temple of Mars Ultor.
