The Daemon Prince: Some musings on Hermes-Mercury

The word ‘mercurial’, taken from the name of the Roman god Mercury and his eponymous liquid metal, generally means ‘volatile’ and ‘liable to change’. This descriptor is an apt expression of the god’s perceived nature as an ever-busy messenger between the divine and the mundane, the organising principle of trade and travel, inspiration for eloquence, dreams and communication, and a great crosser of boundaries. Known as Hermes to the Greeks (who seem to have donated him to the Romans), he was a god whose function these sage peoples also applied the term daimōn, which persisted in the Latin christian world in the word ‘demon’, coming to mean an evil angel who serves Satan in the mundane realms. Very broadly, a daimōn can be thought of as a penetrating principle of spirit entering into and acting on matter – a god-like being. In Plato’s dialogue known as The Symposium, the philosophers at a wine-drinking party discuss how, because of its great power, the principle of love (and hence, the goddess Aphrodite) is in fact a daimōn, for instance. Hermes and Aphrodite were credited in mythology with coupling to produce the androgynous god Hermaphroditus, venerated in the consumation of marriage as an expression of the combination of male and female sexuality.

In Greek,  ‘herma‘ means ‘pile of stones’, ‘prop’ or ‘boundary marker’, and this was the original form by which the god’s numinous presence was imagined in rural districts during and before the Greek ‘Archaic’ period, when gods were frequently depicted such by simple formless objects (such as the wooden ‘xoana’ images etc). The name ‘Hermes’ also resonates with the later Arabic word Emir, meaning ‘prince’ or ‘commander’ of a territory. From the classical period onwards (after the 7thC BCE) depictions of Greek gods increasingly became more figurative, and the word hermai came to be applied to those monuments associated with Hermes: often assuming the form of a simple square pillar surmounted with a carved head of the god, and exhibiting a phallus on the column at waist height. Greek traveller Pausanias, writing in the 2ndC CE, noted the god’s image might take the form of an erect male member mounted upon a pedestal. Such objects were popularly placed next to doorways and at boundaries in ancient Athens. In many ways they were similar to the older Egyptian depictions of the ithyphallic god Min.

To Classical and Hellenistic era Greeks, the square column represented order and stability (the god’s sacred number was four), and the phallus combined symbolism of both penetration and generation. Students of Greek paganism will recognise the phallic imagery as being shared by gods such as Dionysus, Priapus, and the Satyrs of the Dionysian retinue. Sâthe is another Greek word for ‘phallus’.

As Greek religion evolved to incorporate eastern philosophies of essential monism, Hermes increasingly came to represent the divine aspects of the individual – an important factor in the development of christianity. An example of this is the syncretic god-concept of Hermes Trismegistos (‘Thrice-Great Hermes’) whose cult combined with that of Thoth  in Hellenistic Egypt, and who was recognised as a reputed originating author of written religious traditions in the Hellenistic Near East which seem to prefigure christianity in their content (‘Hermeticism’). Both Thoth and Hermes were patrons of written communication, and the Greeks saw the origins of many of their gods in those of ancient Egypt, and also to the converse.

In Roman culture, Hermes came to be identified with Mercury, whose name (and function) is associated with the word for trade – mercare. The god’s function as crosser of boundaries is also represented in the Indo-European languages’ use of variants of the word ‘mark‘, such as the Latin ‘margō‘, which means boundary or border. Trade is, after all, a formalised interface between individuals where both seek to benefit…

As human competitiveness knows no such boundaries, Mercury was also considered the god of magic, tricksters and thieves! In the 4thC CE, Christian writer Arnobius (Adversus Gentes 4.9.1) sneered at the Romans for worshipping their ‘Dii Lucrii’ (‘gods of profit’) of whom Mercury was an obvious case. Rome’s success came from copying the skill in trade of the Greeks and Phoenicians, who had colonised Italy before the city came to prominence. Mercury appears to have been a Greek introduction to Roman religion, with no obvious indigenous equivalent (except the original distinctly agrarian and rustic identity enjoyed by Mars/Quirinus) being known to current scholarship. Julius Caesar’s 1stC BCE comment (Comentarii de Bello Gallico) that the Gauls worshipped Mercury as their chief god was probably an off-hand comment that Gauls worshipped trade and  money – he had certainly managed to buy off the loyalties of many of them in pursuing his conquest of ‘barbarian Gaul. Likewise, the same might be said of Tacitus’ comment a hundred years later that Mercury was the chief god of the German peoples.

The breaking of boundaries and interfaces is also a strong semantic associated with death and travelling to an afterlife, so Hermes and Mercury were ascribed the divine function of psychopomp – guiding departed souls to their allotted destination.  This resonates with the god’s mythological connection with acting as a herdsman, and Hermes was indeed venerated as a protector of flocks and herds – seemingly a more fundamental or primitive aspect of his rôle as guardian of wealth and trade. In the myth of Zeus’ love for Io, tranformed by Hera into a cow, he sends Hermes in the guise of a shepherd to slay the giant Argos Panoptes who watches over her, freeing her to wander the earth.

Throughout the whole body of the text of the ‘Homeric Hymn to Hermes‘ he is portrayed as a rustic god associated with the droving and abduction of cattle and other beasts. Indeed, when he was but a precocious babe in his mother’s arms in a cave high on rustic Mount Cyllene, his first act after birth was steal the cattle of his brother Apollo, and institute the bridge of sacrifice between man and the deathless gods by slaying them. In recompense to his brother, according to the ca. 6th/5thC BCE hymn, he creates Apollo’s mystical lyre from the shell of a tortoise and the horns of an ox.

As a drover of cattle or a drover of souls, he is a leading and conducting force, much in the way that Aphrodite is an inducing and seducing force. He was sometimes imagined and depicted as Hermes Kriophoros – ‘Hermes the Ram Carrier’ – in the manner of a shepherd, carrying the beast in his arms or on his shoulders. This imagery became popular in christianity, whose narrative of shepherding and flocks appears to borrow heavily from the mythology of Hermes. He is almost always depicted (either as Hermes or Mercury) wearing a sun-hat (petasos), this being the signifier of a rustic in Greco-Roman culture: wealth and prosperity of any society ultimately flows from the soil.

Traditional depictions of Hermes and Mercury usually show him wielding a staff or sceptre. From our understanding of his functions, it can be seen that this could easily represent the staff of the shepherd, the measuring stave or tally stick of a merchant, the wand of a magician, the rod of a scribe or the sceptre representing authority in interaction between people. Known as the ‘caduceus’, its depiction became more formalised as time progressed until it assumed the form we often associate with it: a rod around which two serpents are twined, surmounted by a ball, sometimes with wings attached. The serpents are a symbol of regeneration from the earth, of death and rebirth, and also have sexual connotations as well as being largely ‘hermaphrodite’ in appearance, at least from the point of view that they are difficult to sexually differentiate. The twined serpents imply the coupling of male and female, representing the daimonic universal motivating forces implicit with both Hermes and Aphrodite. The wings and serpents together represent the polar opposites – the cthonic earth upon which snakes are doomed to crawl, and the air or pneuma, which is the sky and home of the stars and spirit. This represents the ability of Hermes to link the divine and the mundane. He was the god of transaction in all its forms and the caduceus is a striking representation of this.

Gods of War and Agriculture

The identity of Mars in Roman culture shows a curious transition over the six or so centuries from its establishment as a regional power until its turbulent yet glorious Imperial era. Formed from a synthesis of native Latin, Etruscan, Sabine and Umbrian subcultures under a continuous stream of influence from their Greek and ‘barbarian’ neighbours it was a protean and ever-changing hotbed of innovation in both secular and religious matters. Its gods were therefore just as prone to change, and Mars makes an interesting case study:

Unlike the Greek god Ares, who tended to appear in myths (as befitted Greek warrior culture) as a dangerous quarrelsome outsider, Mars was treated more as an ancestral father-figure for the Romans. Livy (Ab Urbe Condita) recounted his role in Rome’s foundation-myth as father of Romulus and Remus by Rhea Silvia – a priestess of Vesta, identifiable with Vesta herself, otherwise cognate with the ancestral mother deity: Larunda, the Mater Larum. Indeed, Rome’s Etruscan forebears called their god of war Laran, which has similar connotations of the spirits of the departed, known as ‘Lares’. His consort was Turan whose entourage included the Lasas – another archaic name for Lares. Turan was also seemingly associated with birds – a common archetype for souls. She became identified in the Republican era with Venus – Mars’ complementary feminine aspect.

Mars’ agricultural aspect and his link to the ancestral spirits of the Etruscans and Romans is illustrated beautifully in the hymn of the priests known as the Arval Bretheren – the Carmen Arvale – preserved in a temple inscription, and invoking both Mars, the Lares and the fertilising spirits or Semones to bless the fields. The month of March (Martis – named after Mars) marked the sprouting of spring wheat and the beginning of the agricultural season as the weather warmed. Another Roman priesthood – the Salii – celebrated the rites of agricultural Mars, and had their origins back in the ancient Roman kingdom. They carried ancient shields called ancilia, which were kept in Mars’ temple. These were supposedly made by a legendary smith-armourer called Mamurius Veturius, possibly cognate with Mars in the Carmen Arvale under the name Marmor. The connection between the cthonic realm, food and metal seems obvious: the earth renders both. The annual re-forging of nature meant that it would not have been unusual for such a theological connection to have been made between smithcraft and the underworld.

Warfare and metal were likewise connected: War and death also. The annual death and rebirth of nature, and the fertility engendered in soil by dead matter (‘Putrefaction’) were likewise important parts of the same semantic field. In fact, the co-ordinated armies of people required for agricultural endeavours and the tendency for battle to be joined a campo in warfare added to this analogy. Rome and Etruria’s ancient wealth and power depended as much on agriculture as it did warfare, and Roman Mars expressed this idea.

Tied closely to Roman Mars’ semantic field-map are Janus, Mercury, Vulcan and Pluto. Pluto, because of the older connection to the cthonic otherworld and the Lares. Janus and Mercury because of the crossing of boundaries between the worlds, and Vulcan because of the active fiery, reforging aspect of Mars as an agricultural deity.

Elsewhere in Europe where hunting and transhumance and nomadic pastoralism were principle modes of food-production, one might imagine that the ‘herdsman’ aspect of cthonic gods was to the fore, and this indeed proved to be the case. The ‘wild hunt’ of Wotan, Velnias, Volundr, Herla are cases where battle-gods or smith-gods fulfill such roles. Thor was a battler-deity favoured for agricultural protection, as was Hercules.

The Greco-Roman mythological character who was the bestower of wealth was the ‘divine child’ Ploutos/Plutus, an aspect of Plouton/Pluto (related to the Roman gods Dis Pater and Orcus)who was at the heart of the Eleusinian Mysteries, and seems to have had a certain similarity to Cthonic Mars. Plutus was the child of Demeter and the Hero, Iasion, who made love to the goddess in a ‘thrice ploughed field’. The birth of Plutus might therefore have a parallel to the birth of the Etruscans’ ‘divine child’ Tages, who emerged from a ploughed field and gave knowledge of Augury and Haruspicy to the people. Knowledge of Sorcery or any form of Augury was to be found in the province of the dead… Mercury/Hermes was the ‘psychopomp’ responsible for conducting souls to this realm, as well as being the god of trade and pecuniary increase – the gift of Plutus transmitted in his hands back to this world from the Otherworld! Janus was also identified with the archaic member of the first Capitoline Triad, the Sabine god Quirinus, who was sometimes identified as a deified form of Mars’ divine son, Romulus. He ‘stood’ over the gates between the Otherworld and this world, and presumably allowed the two-way interaction between the spirit and elemental worlds to occur. Mars himself was therefore a conduit of masculine vital force from the spirit world which influenced the mundane world in a positive way. He was a keystone for the functions of a number of other gods, and was therefore one of the most important of Roman deities, and was venerated (under this wider identity) more than any other in the Romanised Celtic world…

The Celtic Sun God

“…in ancient days first of the long-haired nations, on whose necks once flowed the auburn locks in pride supreme; And those who pacify with blood accursed savage Teutates, Hesus’ horrid shrines, and Taranis’ altars cruel as were those loved by Diana, goddess of the north; All these now rest in peace. And you, ye Bards, whose martial lays send down to distant times the fame of valorous deeds in battle done, pour forth in safety more abundant song. While you, ye Druids, when the war was done, To mysteries strange and hateful rites returned: To you alone ’tis given the gods and stars to know or not to know; secluded groves your dwelling-place, and forests far remote. If what ye sing be true, the shades of men seek not the dismal homes of Erebus or death’s pale kingdoms; but the breath of life still rules these bodies in another age…” Lucan –Pharsalia 1stC AD

Lucan’s famous account attempts, in a few lines, to sum up the whole religious worldview of the defeated Gauls – one which he portrays as once savage and dangerous. He names four gods – Teutates, Hesus and Taranis, and very interestingly ‘Diana, goddess of the north’. It is perhaps surprising that he fails to mention by name the two particular gods who seem from epigraphic, numismatic, literary and historical evidence to have been very prominent in religious landscape of the Celts: Bel(enos) and Lug.

Julius Caesar, instigator of the ‘glorious’ events recounted in the Pharsalia, claimed that Mercury was the Gauls’ chief god:

“…They worship as their divinity, Mercury in particular, and have many images of him, and regard him as the inventor of all arts, they consider him the guide of their journeys and marches, and believe him to have great influence over the acquisition of gain and mercantile transactions…” (De Bello Gallico, Book 6)

Secondarily he mentions that they also worshipped Apollo, Mars, Jupiter and Minerva. ‘Teutatis’, ‘Esus’ and ‘Taranis’ are the names Lucan gives for Caesar’s interpretatio romanum of ‘Apollo’, ‘Mars’ and ‘Jupiter’ but in Pharsalia, he substitutes ‘Minerva’ with ‘Diana’. Given that he was writing almost 100 years after Caesar’s Gaulish conquest, it is fair to say that he may have had better information, but it is clear from the tone of Pharsalia that Lucan considered continental Celtic culture (except, of course, for the poetic arts) to already have been largely smashed and replaced by the Romans. So what of the Gaulish ‘Mercury’ mentioned by Caesar? On this he seems – on the face of things – to be silent, but analysis reveals a more interesting aspect:

It is fairly self-evident from Pharsalia, that Lucan has used Caesar as his source, albeit updated with the names of the indigenous gods. Lucan’s version, however, commences not with a mention of Mercury but with the allusions to the overly-proud barbarians and their fiery flowing locks of hair. Pride, as they say, comes before a fall – and perhaps the greatest and well-known example of this for the people of the ancient Roman world was the story of Alexander of Macedonia – whose ambition so famously over-reached his ability to outlive his conquests. The Celts were well aware of Alexander – they used his image on almost all of their coins.

So, what is the connection between Celts, Roman Mercury and Alexander? Caesar’s statement about the ‘many images’ of Mercury is interesting when one considers the most prevalent images created by the Celts were not apparently statuary idols, but coins. To the Romans and Greeks, Mercury (Hermes) was the god of trade, crafts and was generally seen as what Plato might have termed a Daemone or spiritual intermediary between man and the gods. He was also the god of poets such as Lucan perhaps being the reason Lucan does him honour with a form of circumlocution when repeating Caesar’s account of Celtic religion. Mercury was also the psychopomp who conveyed the souls of the dead on their mystical journey – something which was of core interest to Celtic religion, and upon which Lucan remarks. He was usually depicted wearing a winged traveller’s sun-hat or petasus and with winged shoes. It is therefore not inconceivable that the similarity between the ‘horned Alexander’ iconography of the coins and the images of Mercury common in the Greek and Roman world led to Caesar’s assertion that the Gauls venerated Mercury as their chief god. Indeed, on the Gallo-Roman ‘Pillar of the Boatmen’ from Lutetia (modern Paris) on the Seine, the horned figure ‘Cernunnos’ occurs. Note that his horns are adorned with rings – possibly symbolic of the older form of Celtic money before coins became popular:

Horned figure from the 'Pillar of the Boatmen', named 'Cernunnos'.

Horned figure from the ‘Pillar of the Boatmen’, named ‘Cernunnos’.

‘Cernunnos’ is a name obviously derived from the Celtic name for ‘Soldier’ (Cern), and he appears to be wearing a helmet with stags antlers on it: The image of the stag with adorned antlers is specifically associated with therut’ during which combats occur over mating rights, typically at territorial boundaries such as on plains near river crossings (such as with the battles in the Irish epic tale Tain bo Culainge). In a warrior-pastoralist culture the link between battles and fecundity is explicit in this image. In the same way, the branch is a symbol of fecundity for more arable-agrarian societies, and was widely used in Greek and Roman iconography. In fact, the antlers combine both images on account of their shape.  Wings for that matter are also branched, as are bolts of lightning and rivers. The Pillar des Nautes is awash with Roman-Celtic syncretism.

So – the god of wealth and fertility whom Caesar likened to Mercury and had ‘many images’ made of him was represented using the traditional image of Alexander with a cornucopia attached to his head. Lucan’s triple-set of names: Teutates, Hesus and Taranis (and their ‘blood-stained’ altars) may well all be a ‘triple aspect’ of the one he leaves un-named, teasing us with his palpable circumlocution of the underlying divinity he must have realised was represented. Lucan was a clever lad, and the gods (no doubt Mercury himself) were to receive him into Elysium at a young age – a ‘rock and roll’ life and death.

But what about ‘Belenos’? Or, for that matter, ‘Lugus’? What even of the ancestor-god Caesar remarked upon as being called (or like) Dis Pater…. Might they all be one and the same?

In terms of likeness to Mercury, it is Lug(us) who has usually been given this honour, and for whom there have been parallels found in the mythology of the ‘surviving’ Celtic language cultures of Wales (Lleu) and Ireland (Lugh), both of which associate with crafts. Lug (like Belenos) appears in placenames and inscriptions from all across the Atlantic European world, and into the reaches of the Danube river basin.

Evidence for Belenos’ prominence is shown by tribal or kin-group designations such as ‘Belgae‘, and personal names such as that of British King Cunobellin(us) (1stC AD).   In the early medieval ‘Harleian Genealogies’ (British Library Harleian MS 3859) of the Kings of west Britain (Wales) and the ‘Henn Ogled’ (Old North – Southern Scotland down to Lancashire), ‘Beli’ and his wife ‘Anna’ are named as the ultimate ancestors of King Owen of Gwynedd. Anna is even said (like Brighid in Ireland) to be a relative of the Virgin Mary – further proof of attempts at early christianising attempts at syncresis with biblical narratives:

“…Beli magni filius, et Anna, mater eius, quam dicunt esse consobrina Mariae uirginis, matris Domini nostri Iesu Christi. …”

With the Romanisation of the barbarian Celtic cultures, the worship of Bel/Belenos would become submerged in the cult of Apollo, demonstrating that Bel/Belenos was an overtly solar deity.

The association of Apollo Grannus with Mars at various spa shrines in the Romano-Celtic world maintains the martial link of the Celts’ beloved warrior/sun-god icon, Alexander, whose conquests (and failure) had inspired the Celtic invasion of the Balkans, Thrace, Macedonia, Greece and Phrygia in the 3rdC BCE. At some of these, the ‘Celtic’ Mars is also sometimes depicted in attire we would more associate with Mercury, demonstrating a syncresis between the two Roman gods in the Celtic mindset:

A 'Celtic Mars' - note the combined imagery of Mercury and the warrior

Some depictions even show Mars with wings – perhaps a convenient spiritual representation of what the Celts desired: Death in glorious battle and an ‘autopsychopompic’ flight to the Otherworld.

A 'winged Mars'. Cunobelinus had a winged figure on some his 1stC CE coins.

A ‘winged Mars’ – A winged figure is also seen on some Celtic 1stC BCE/CE coins. The horse depicted is also sometimes winged.

The conjecture I should like to raise again is this:

That the Atlantic Europeans before the Romans had a principally duotheistic religion comprising of a god and a goddess who each had a ‘triple’ identity. The imposition of Roman culture and then the overlay of Christianity created a ‘Celtic Pantheon’ which in truth never really existed. ‘Lugh’, ‘Belenos’, ‘Teutates’, ‘Esus’, ‘Taranis’ were all epithets of the same solar deity who conducted the souls of the dead in their Otherworld destinations. His companion ‘Diana’ (De Áine) had similar multiple-epithets and was associated with the worldy creation and manifestation.

Caesar on Celtic Religion

Julius Caesar’s memoir Commentarii De Bello Gallico (‘Commentary On the Gallic War’) was an account of the Roman army’s subjugation of Gaul in 51BCE and which he himself led.

The work is famous for its descriptions of the enigmatic priestly caste of the Gauls: the Druids. These were leaders of the ancient religious system then common to Gaul, Britannia and Hibernia/Scotia (Ireland). He says very little about the religion itself, being more interested in expressing the Druids’ political and social importance, but he does give a few tantalising details… (Translations by W. A. McDevitte and W. S. Bohn)

They wish to inculcate this as one of their leading tenets, that souls do not become extinct, but pass after death from one body to another, and they think that men by this tenet are in a great degree excited to valour, the fear of death being disregarded.

… and about their gods he has this to say:

All the Gauls assert that they are descended from the god Dis, and say that this tradition has been handed down by the Druids.

As well as naming ‘Dis’, Caesar used the convention of giving Roman names for the rest of the gods of the Gauls and describes ‘Mercury’ as their chief deity, as well as Apollo, Mars, Jupiter, and Minerva. As war is perhaps the least satisfactory arena in which to study cultural anthropology, his is probably a very rough and unreliable overview of the reality of Gaulish religion. After all, this was an era where even the Romans were confused about their own gods and religion: To contemporary intellectuals (such as followers of the 4thC BCE Hellenic philosopher Plato) gods were scientific expressions of universal phenomena, not to be taken literally. To the masses, they were a literal truth – an unseen power made visible and understood through images and ceremonies. Religion was diversifying at an alarming and unsustainable rate. His appraisal of the Gauls and the contradistinction he makes with the German tribes in chapter 21 (where he claims that they had no druids and worshipped only what they saw – the sun, fire and the moon) have underpinned the study of European paganism ever since, but it is likely that the Gauls, Britons, Irish and Germans probably shared very similar beliefs, which the mediterranean mind found it difficult to conceptualise.

The thing is… there is very little evidence of the exact nature of Pre-Roman/Pre-Hellenic religion among Iron Age ‘Celtic’ or German tribes. What exists is – like Caesar’s account – seen from a very jaded Roman or Greek viewpoint. There is ample evidence of Romanised ‘Celtic’ deities from the next 5 centuries after Caesar, and even before he took Gaul its southern part was under the cultural influence of the Hellenes (and was probably itself influential upon the Greek world). Familiar attested names of ‘gods’ such as ‘Toutatis’, ‘Taranis’, ‘Belenos’, ‘Cernunnos’ and so forth remain as popular totems that have scant evidence linking them to a systematic beliefs, and perhaps the biggest problem is that folklore from the more modern celtic world that preserves obvious and fundamental pre-chistian beliefs does not offer much support for a Roman-style pantheon of gods. The reasons for this need to be and will be investigated in my writing.

The most important key belief that Caesar mentions is that the soul flies free of the body after death and returns to another corporeal existence in time. Such a belief is the core of an ancestor-based religion. Also the Gaulish god Caesar calls ‘Dis’ (to the Romans a psychopomp or conductor of souls, and guardian of the earth’s fertility and mystery) was believed to be the racial forefather, thus making him/it the key archetype god for this soul-belief. When he omits mentioning ‘Dis’ in his assessment of Gaul’s most important totem gods in the previous chapter, he is probably seeking to discourse on something the Romans knew more about. Roman ‘Mercury’ (Hermes to the Greeks) was also a psychopomp (conductor of souls) and Caesar may well have been using the names ‘Mercury’ and ‘Dis’ (as well as ‘Mars’, ‘Apollo’ and ‘Jupiter’) to refer to the same important progenitor divinity, and I will present evidence for this in due course. His intention with the interpretatio romanum was also possibly an attempt to orientate his Roman readers to similarities between them and the Gauls, especially as many would own Gaulish slaves as a result of his campaign. The core domestic (and plebian) religion of Rome was, after all, based upon ancestor-spirit worship (of ‘Lares’ and ‘Genii’ as well as ‘Lemures’, ‘Larvae’ and ‘Manes’) and veneration of the ‘eternal gods’ (Jupiter etc) was generally seen as a more high-minded and public affair, albeit open to fads and trends, and imperial decree. The Roman beliefs in disincarnate souls therefore showed a distinct commonality with their ‘Celtic’ neighbours, and is in evidence among Rome’s Etruscan forerunners.

In christian times, it seems that stubbornly tenuous pagan ideas about discarnate ‘souls’ were to become identified with ‘fairies’ – spirits who inhabited an inverted parallel world to our own, their daytime being our night, and vice versa… Fairy belief was to become a cultural shibboleth of Atlantic Celtic peoples.
