Medieval Nordic vernaculars routinely use the terms dreki (pl. drekar), โdragonโ, and ormr (pl. ormar), both โserpentโ and โdragonโ, in often overlapping ways, although clearly dreki, a word of foreign origin (< Latin draco, from Greek drakลn) has the more restricted range, never referring to snakes as such, but always, and only, to the kind of serpentine beasts known from myth and legend.1 By contrast, ormr, cognate with Old English wyrm โsnake,โ โdragonโ and so on, is employed to mean both the actual reptiles of the suborder Ophidia and cryptozoological monsters. So intertwined are the two in medieval texts and in artistic representations that one scholar has suggested the Swedish neologism drakorm (pl. drakormar) as a means of referring to the two as a group.2
In surviving texts concerned with Old Norse mythological and legendary traditions, modern readers encounter three especially well-known dragons: Nรญรฐhวซggr, the Miรฐgarรฐsormr, and Fรกfnir. There are other named dragons and other terms, of course, as Snorri remarks in his Skรกldskaparmรกl:
รessi eru orma heiti: dreki, Fรกfnir, Jวซrmungandr, naรฐr, Nรญรฐhวซggr, linnr, naรฐra, Gรณinn, Mรณinn, Grafvitnir, Grรกbรกkr, รfnir, Svรกfnir, grรญmr.3
These are the names for serpents: dragon, Fafnir, Iormungand, adder [naรฐr], Nidhogg, viper [naรฐra],4 Goin, Moin, Grafvitnir, Grabak, Ofnir, Svafnir, masked one.5

What these legendary drakormar of Norse tradition have in com-mon with the well-known dragons of Christian tradition, such as those that do combat with Christian heroes such as Saint George, is that they are typically seen to have negative associations, that is, generally negative and adversarial relations with human society: according to Vวซluspรก in GKS 2365 4to, Nรญรฐhวซggr, for example, inn dimmi / dreki fljรบgandi (โthe dark dragon flyingโ) bears corpses รญ fjวซรฐrom (lit., in [his] feathersโ; Vวซluspรก (K) st. 63 cf. Vวซluspรก (H) st. 58) and is said in Grรญmnismรกl (st. 35) and Gylfaginning to gnaw (skerรฐir) at the roots of the World Tree.
This adversarial โman versus monsterโ scenario, the central image of the various story lines gathered as motifs A876, A1082.3 and so on in The Motif-Index of Folk-Literature,6 is one that has ancient roots: not only the North Germanic peoples but also many other Indo-European cultures โ i.e., Italic, Indo-Iranian, Celtic, Greek, Anatolian and other historically- and linguistically-related traditions โ were, according to Calvert Watkinsโ How to Kill a Dragon: Aspects of Indo-European Poetics,7 inheritors of a millennia-old formula of the following sort:
(HERO) SLAY (*guhen-) SERPENT (WITH WEAPON; alt., WITH COMPANION)
It is, of course, a tale that recurs in the myths and legends of many Indo-European cultures, for example, in the storied confrontations between Zeus and Typhon, Herakles and the Hydra, Perseus and the Gorgon, Indra and Vแนtra, and, in the Nordic case, รรณrr and the Miรฐgarรฐsormr.
Given this well-documented archaic story pattern and such popular Christian presentations of dragons in the Nordic Middle Ages as the legend of Saint George, it seems that the principal way these beasts ought to be understood is within an adversarial context; however, several scholars have been at pains to argue for a different perspective on pre-Christian perceptions, and uses, of dragons. Basing his interpretation on close examination of Bronze Age rock art and images on bronze objects, Flemming Kaul has proposed an integrated understanding of what he has termed the religion of โthe solar ageโ (solalderen).8 According to Kaulโs anal-ysis, this is a belief system connected to a social elite exercising control of, and trade in, bronze.9 In it, the drakorm provides assistance to the sun in its daily movement by leading it below the horizon for its nocturnal aqueous passage.10
On the significance of such an understanding of Bronze Age religion in the North for the Germanic Iron Age many centuries later, Kaul thinks such continuity unlikely, mainly due to what he understands to be two periods of disruption: one c. 500 BC with a change in ritual patterns, and another, c. 500 AD, with the establishment of a religion centered on the รsir. But, even if he thinks the possibility slight of there being any meaningful comprehensive connections between the Bronze Age materials and, for exam-ple, later written sources, Kaul concedes that some of the earlier motifs, including the snake motif, may have been transformed in ways that allowed them to survive into the Iron Age.11
Birgitta Johansen, also an archaeologist, concludes as well that there may have been generally positive relationships of drakormar to human society. Treating the Roman Iron Age up through the Middle Ages (200 CE โ1400 CE), Johansen examines the evolution of social and mental constructs, especially as these are to be inferred from the natural and built landscapes (e.g. hill forts, stone walls), and their interrelationships. Johansenโs interpretation relies heavily on what she sees as the contrasting views of pagan vs Christian Scandinavia, especially as these perspectives are employed in dragon imagery on rune stones.12 Johansen argues that the previously positive connection between drakormar and women turns negative under Christianityโs influence:
My conclusion is that women are the users of the dragon (even explicitly against men) and that the dragon protects women. The dragon fights with men and it kills men. These roles eventu-ally changed, the dragon increasingly becoming a threat to men and something men could control only by killing. In addition it became, during the Middle Ages and under Christian influence, a deadly threat to women too.13
Thus, against the view that human relations to drakormar were necessarily negative, as in so many Indo-European sources and such Old Norse narratives as those about รรณrr and the Miรฐgarรฐsormr, an alternative, positive interpretation also emerges for the pre-Christian era. Recognizing the possibility then that there may have existed two distinctly different interpretations of drakormar in the Iron Age, how might our understanding of the drakorm figure as seen in Gotland be re-interpreted?
Drakorm elements figure strongly in the islandโs art tradition, and a number of Gotlandic picture stones provide important clues about the drakormโs status. Frequently, these images come from the earliest era of the Gotlandic picture stones,14 a turning point in the history of religious and cultural life in northern Europe.

From the earliest periods, Lindqvistโs group Aa, now understood to include the 2nd through the 6th centuries,15 such drakorm images as Martebo Church (G 264) (Fig. 1) and Hangvars Austers I, for example, testify to the popularity of the dragon-snake motif within the islandโs art traditions. For the most part, these depictions appear to fall well within the adversarial dragon tradition.16 A related, but much more complex and divergent, use of drakormar is also one of the best-known Gotlandic picture stones to the world at large, namely, the remarkable monument from Smiss in Nรคr Parish, discovered in 1955, sometimes called the โsnake witch stoneโ (Swedish ormhรคxan, alt., ormtjuserskan).17

Nรคr Smiss III (Fig. 2) is usually dated to the 6th to 7th centuries (although some have suggested that it might be from as early as the 5th century).18 In it, rather than the dominating central whirling solar figures on Martebo Church (G 264) and Hangvars Austers I, Nรคr Smiss III has instead a large triskele of three animals, often interpreted as a boar, a raptor, and a drakorm. Beneath this group is the figure of a human, generally, although not always, believed to be a woman, legs outstretched, holding two differing drakormar, one in either hand.
Interpretations of this stoneโs origins, history and meaning have been much discussed, although little agreed on โ already its discoverer, Sune Lindqvist, brought not only Norse but also Celtic and Minoan traditions into the debate and these possibilities have tended to dominate discussion ever since. The stone has, for example, been understood to be a product of Celtic artisanship representing Daniel in the lionโs den;19 others have also promoted possible Celtic connections, especially to the degree to which the image has been likened to the god, Cernunnos, as presented on the Gundestrup Cauldron.20 Karl Hauk sees in the figure a shape-shifted รรฐinn in the form of a Seelenfรผhrer.21 And comparisons with the famous Minoan snake goddess figurines from the โhouses of the double-axeโ in Knossos and other Cretan towns are highly suggestive but of uncertain value given our current state of knowledge. The very uniqueness of this stone among Gotlandic picture stones makes the object difficult to assess, although one need not be quite so pessimistic as the Harrisons, who include the stone in their 101 fรถremรฅl ur Sveriges historia noting simply that โwe havenโt a clue about what the stone saysโ.22

By contrast, local historians and other enthusiasts have been neither silent nor uncertain about this remarkable stone, and we may, in fact, be able to provide a context which at the very least situates Nรคr Smiss III within an empirically-based matrix, such that it no longer seems so utterly sui generis. Of particular interest, despite being half a millennium later than Nรคr Smiss III, has been a 12th-century stone relief at Vรคte Church, Gotland (above).
It has sometimes been suggested that such scenes are legacies of a pre-Christian belief in Terra mater, the earthmother, nursing beasts, including serpents. Another, and in my opinion likelier, interpretation is that it reflects an interest in such vision literature as e.g. the 4th-century Vision of Saint Paul, the 5th-century Apocalypse of Elijah, or the (contemporary) 12th-century Vision of Alberic, all of which present women condemned to nurse serpents in Purgatory/Hell, because they have refused to care for orphans, or, in other instances, their own children. And in Continental church art, these unusual scenes of multispecied nursing are understood to be a punishment for lust and debauchery, an idea occasionally applied to Vรคte as well;24 moreover, similar scenes are also found in medieval homiletic literature, which again point to envy and lust as the causes of this unusual suckling.25 Recent arguments have pushed back against this ecclesiastical interpretation and contended anew that it is, in fact, Terra mater and not Luxuria that is being presented here and elsewhere in Nordic contexts.26
Importantly, one of the other sites comes from the church at Linde on Gotland, part of a baptismal font described as showing โa standing woman with a โsnakeโ [orm] at one breastโ.27 Naturally, the origin of the medieval drakorm-nursing images at Vรคte and Linde are most easily explained by these ecclesiastical references โ yet whatever the Churchโs specifically theological rationale, nothing about this scene dictates that islanders who knew of a traditional association of women and drakormar could not interpret it in ways that were convivial to local beliefs and customs, an association that could, in fact, have played a role in the Churchโs selection of this theme. The two images at Vรคte and Linde are hardly a large dataset and one might reasonably conclude that these unusual human-drakormar interactions are merely examples of the so-called โinfinite monkey theoremโ. Yet, as already strongly hinted at in Peelโs edition and translation of medieval Gotlandic law and legend,28 there are, in fact, several other significant indications of a local tradition involving drakormar.

Although the human figure on the lower portion of Nรคr Smiss III is unique on Gotland, the triskele design on the upper portion is not. In fact, in reviewing the archaeological record from the period 550โ750 CE,29 it is clear that designs similar to the Nรคr Smiss III triskele are a common feature of Gotlandic iconography throughout these pre-Viking periods, as in the following examples of perforated discs.30

The design of these artifacts, of which there are a great many from Gotland, strongly resembles the triskele on Nรคr Smiss III (although it shows three different animals), especially when it is presented in a similar style (Fig. 5).
One particularly interesting item in this inventory (item c in Fig. 4), as noted already in Peel,31 comes from an early 9th-century Gotlandic grave for a woman at Ihre in Hellvi Parish in northeastern Gotland. Although the grave itself dates to the 9th century,32 it has been argued that the object may date to the period 650โ700 CE.33 One possible interpretation of this chronology would be that the disc, as a noted archaeologist suggests โmight have been an antique when it was buried and this raises the possibility of such decorative discs having been heirlooms passed from mother to daughterโ.34
The continuity of these ornamental discs, their style, and their concern with drakormar brings to mind, as is occasionally mentioned on online sites about Gotland, that also concerned with women and serpents is an important episode in the so-called Legendary History of Gotland from the 13th century:
รissi รieluar hafรพi ann sun, sum hit Hafรพi. En Hafรพa kuna hit
Huitastierna. รaun tu bygรพu fyrsti a Gutlandi. Fyrstu nat, sum
รพaun saman suafu, รพa droymdi henni draumbr, so sum รพrir ormar
varin slungnir saman i barmi hennar, ok รพytti henni sum
รพair skriรพin yr barmi hennar. รinna draum segรพi han firir
*Hafรพa, bonda sinum. Hann *reรพ draum รพinna so:
โAlt ir baugum bundit.
Boland al รพitta varรพa,
ok faum รพria syni aiga.โ35
This same รieluar had a son named Hafรพi, and Hafรพiโs wife was called Huitastierna. These two were the first to settle in Gotland. The first night that they slept together, she dreamed a dream. It was just as if three snakes were coiled together within her womb, and it seemed to her as though they crawled out of her [womb]36. She related this dream to Hafรพi, her husband, and he interpreted it as follows:
โEverything in rings is bound.
Inhabited this land shall be;
we shall beget sons three.โ
This legendary text as a whole has been the subject of much discussion over the decades,37 and although its immediate context โ the Laws of Gotland โ suggests that it largely functioned as a framing device for these important documents, few doubt that much of the material in the history offers us insights into the early history and traditions of the island.38 The opening settlement or foundation legend, for example, has numerous parallels, including the three brothers, but virtually without parallel is the notion of Huitastierna dreaming of having three snakes coiled in her womb who are subsequently born and who, as humans, settle the island.
A somewhat similar tale is the dream reported about Clytemnestra in the second of Aeschylusโ Oresteia trilogy, Choephoroi (The Libation Bearers), according to which Clytemnestra has given birth to a monstrous and vengeful snake. But even if the basic idea โ an elite woman giving birth to one or more snakes โ is the same, it is in one instance meant to be a real snake and in the other a dream to be interpreted, like the cows and corn that Jacob reveals to pharaoh (Genesis 40โ41); moreover, the consequences of the dreams are quite different.39 On the other hand, the association of snakes with birthing can boast many parallels: the resemblance of entwined snakes to the umbilical cord, a perception that leads to the connection, and perhaps even metonymy, of this funiculus and snakes, is a phenomenon well-documented in a variety of ancient and modern cultures.40 Moreover, the skin-shedding or sloughing (edysis) of snakes has led to the association of these animals with concepts of re-birth in e.g. ancient Egyptian and Mesoamerican cultures.
The occasional attempts to link this episode of the Legendary History to Nรคr Smiss III might easily be dismissed as an exuberant exercise in local pride, yet viewed in the context of the decorative disc from Ihre and the other Gotlandic drakorm triskeles that suggest a long-standing preoccupation with these motifs, it is worth noting that that keen native observer of Gotlandic history and culture, Hans Nielsรถn Strelow (1580sโ1656), makes much of the continued popular importance in his day of Huitastierna and her role in creating the identity of the island, concluding by saying that โThe Gotlanders ascribe much to herโ (Hende tilskrifuer Guthilenderne megit).41

Two further data points can be added to this puzzle, one from the Danish โsolar ageโ, the other broadly contemporary with the Iron Age materials from Gotland. The Bronze Age votive offering from Fรฅrdal in Jutland โ the most impressive of several Bronze Age scenes Kaul sees as representing humans, snakes and drinking/suckling โ consists of some five bronze pieces (Fig. 6), among them, a kneeling woman and a serpentine beast.
In his interpretation, Kaul argues that the woman is turning toward the snake, โand with her hand she is holding her breast, presenting her breast to the snake, as if inviting it to drinkโ;42 moreover, he suggests that the hole made by the womanโs closed hand and the hole in the head of the serpent indicate that the two had been connected with a line.
Furthermore, recent research by Sigmund Oehrl on Gotlandic picture stones using RTI technology, and presented at the 2015 Stockholm Mythology Conference, considerably strengthens the possible correctness of the argument here. The advanced techniques offered by RTI have led Oerhl to an entirely different understanding of the depiction usually described as being of Gunnar in the snake pit on the Klinte Hunninge I picture stone. This monument was assigned by Lindqvist to the 8th century; current research places its group to the late 8th to 10th centuries.43 The newly revealed tableau, especially in light of the current discussion, looks like nothing quite so much as a birthing scene โ a recumbent woman,44 assisted by one, perhaps two, midwives, and accompanied by drakormar. To this, one might add Kaulโs understanding that snakes in his reconstructed Bronze Age religion assisted the sunโs transition between worlds โ perhaps this function has translated over time into drakormar helping the childโs transition into the world during childbirth.
Is it possible then that we see in these Iron Age materials the echoes of a tradition with deep roots involving women, drakormar, and parturition, a tradition which, at least by the time of our medieval text, has become the โmythโ of Huitastiernaโs vision of ormar and the origin of the islandโs population โ and also a tradition the Church appropriated to its own ends at Vรคte and Linde, returning closely, visually at least, to Kaulโs lactating Fรฅrdal figurine? That is a long leap, I realize, and, if anything, we should view such a scheme with healthy skepticism, but such an evolution would both explain our data and conform to them. Certainly, I do not insist on such an interpretation, yet I hope by focusing on the Gotlandic materials we now have a better purchase on how drakormar may have played a role in the lived lives of Gotlanders in the Merovingian Period and later.
