(For context, I advise you to also look at my post: ‘Gods of war and agriculture’)
Rome’s ancient god Mars represents a curious religious dialectic: On the one hand, he is perhaps best known as a god of war, and on the other he has an older more mysterious incarnation as a god of agriculture and earth’s riches. He remained one the most popular gods of the state religion up until its conversion to christianity.
” … Mars enim cum saevit Gradivus dicitur, cum tranquillus est Quirinus … “
” … When furious, Mars is called Gradivus, when peaceful he is Quirinus …”
Maurus Servius Honoratus – Commentary on the Aeneid of Vergil (early 5thC CE)
This dual nature was illustrated by the Romans in the god’s twin symbols of the shield (the passive or protective) and the spear (the active), represented in his (astrological) symbol, comprising of a circle and an arrow: ♂
In Livy’s great 1stC BCE/CE euhemerist (for which we might read ‘fictive’) account of Rome’s history and founding myth (Ab Urbe Condita), the culture-hero twins Romulus and Remus were said to have been born to a mother called Rhea Silvia. She was the daughter of the rightful king of the legendary founder-kingdom of Alba Longa who supposedly sired the twins with the god Mars, while being forced to serve as Vestal Virgin by the usurper, Amulius. Rhea Silvia’s identity seems to very consciously evoke the great mother-goddess of Greek myth – Rhea – whose name appears to be a metathesis of that of the other arch-goddess: Hera. In the theme-story probably borrowed into that of Rome’s legendary founding twins, Rhea gives birth to Zeus while hiding in a cave on Crete’s Mount Ida, lest her consort Kronos find and devour him. Likewise, Livy says that Romulus and Remus were rescued from destruction by the jealous Amulius who throws the twins into the Tiber, only to be thwarted when they wash ashore and are rescued by a she-wolf. A similar Greek/Cretan myth dealing parturative peril tells of the birth of Dionysus to Demeter/Persephone under similar circumstances. The other myth of that god’s birth to Semele also has the same elements, although both portray Dionysus as being destroyed and reborn. These share elements with the older Egyptian myths of Osiris and Isis, the death and dismemberment of Osiris, his reconstruction and the birth of Heru/Horus. The narrative seems to be a continuity of the idea of life coming from death – an idea at the heart of ancient paganism, one pertinent to understanding Mars. The ‘two faces’ of Mars: Mars-Gradivas and Mars-Quirinus as mentioned by the Christian author Servius, seem to have been united to Old Jupiter in the original ‘Archaic Triad’ of Rome’s principle gods: Jupiter, Mara and Quirinus. This ‘Archaic Triad’ supposedly had its own triad of Flamines Maiores said to have been appointed by legendary king, Numa Pompilus, who was supposed to have ruled in the 8th/7thC BCE. However, it was supposedly supplanted by Hellenised Etruscan influence – either of the Tarquinian kings, just before the dawn of the Roman Republic in the 6thC BCE or by a more gradual process of adoption of state cults from conquered cities. Livy, for instance, states that Juno was adopted when Rome conquered Etruscan Veii in 396BCE, although such a statement does not preclude her already being a god to whom the Romans gave Cult. This ‘Capitoline Triad’ of Jupiter, Juno and Minerva, copied the Etruscan triad of Tinia, Uni and Menerva, respectively. Mars was replaced with the similarly spear and shield-wielding goddess, Minerva, known to the Greeks as Athena – a principle protectoress (as Athena Polias/Pallas) of the city-state in the archaic and classical eras – Athens, in particular. Juno (Hera to the Greeks) was also a feminine representation of a vengeful force who in mythology often attempts to protect (with varying degrees of success) the bonds of her marriage to Jupiter/Zeus. Both female replacements for Mars and Quirinus represent feminine aspects of the male gods. It was noted by Macrobius in his 5thC CE book Saturnalia – that Juno was (etymologically) a female counterpart of Janus, another uniquely Latin god who was depicted with two faces. As god of beginnings and endings, he also played an important role in warfare, it being a custom (according to Plutarch and others) to keep the doors of his temple open in times of war. Janus is an interesting god to introduce to the narrative of ‘two-headed’ Mars: In the time of Augustus this god was actually referred to (by Festus and Livy) as ‘Janus-Quirinus’, implying some kind of link to Rome’s ‘Cthonic Mars’. In the case of Livy (History I.32.6-14), Janus Quirinus was supposedly invoked in the act of formally declaring war. Livy’s account of the words are probably a fanciful concoction of his own typically grandiose style, but the details still count:
“Hear thou, Jupiter, and thou, Janus Quirinus, and all ye heavenly gods, and ye terrestrial gods, and ye infernal gods, hear! I call you to witness this people – naming whatever people it is – are unjust and do not render just reparation. But regarding these matters, we will consult the elders of our fatherland, how we may aquire our due.”
In other words: ‘I’m going to go home and tell my dad, and then you’ll be sorry!’
This and the custom of opening the temple doors equates Janus resolutely to the Archaic triad of Jupiter-Mars-Quirinus under a military aspect. Why, then did Rome adopt the Capitoline triad in its place? It certainly was not averse to war – indeed, the doors of the temple of Janus were probably more often open than closed! The key to understanding the answer to this question is to be found by looking at the females behind the Capitoline triad.
Minerva was the feminine counterpart to Mars in his role as war-god, and was depicted with the same attributes: the spear and shield. However, she was also the goddess of intellect and wisdom – those crucial characteristics which avert war or guide it to its successful conclusion. It is perhaps the fundamental incompatibility between Roman Mars (who was also a chthonic agriculture-fertility deity) and the Greek conception of the war-god – Ares – who represented simply the idea of aggression and violence, devoid of the regenerative qualities implicit in Mars. Minerva herself was a ‘virgin’ goddess – an idea which did not necessarily imply chastity (in the sense so lauded by early Christians), but rather maximum fertile potential.
Juno (Uni to the Etruscans, and Hera to the Greeks) represented the maternal protective force – jealous and fiercely protective, much like the wolf who adopted Romulus and Remus as her ‘pups’ in the old Roman foundation myth. She was the ‘Capitoline’ replacement for Quirinus, who is sometimes portrayed as a deification of Romulus, Mars – like Minerva – being the younger more active version of the god. Jupiter is Juno’s husband in conventional mythology, and Jupiter was the principle god to which warfare was dedicated. Greek and Roman legends are full of the conflict with Hera/Juno caused by Zeus/Jupiter’s constant seeking for mistresses by which conceive the other gods and demi-gods who people Mediterranean myth. In these, her jealousy seeks to protect the older order – their own union. She is thus a more mature aspect of Minerva, her daughter. In Greek and Etruscan myth, she is the nurse-maid of the ‘culture-hero’ Hercules/Herakles (who bears her Greek name), allowing him access to Olympus as a divine – much like the later myth of the she-wolf who suckled Romulus and Remus, allowing them to found Rome. Again, we can see how syncresis with Greek myths informed a change in the focus of Roman religion. Greeks tended to see their Roman cousins as closer to barbarians, and Romans were typically conscious of this in attempting to follow Greek religion.
