IRON AND THE NORSE
The transmission of Norse culture or materials to the Thule during the Norse interchange was often anything but straightforward. In this passage, we’ll explore the presence and role of iron in Norse culture in the East Settlement of Greenland, and how it interacted with the Thule.
The Norse were experienced and relatively sophisticated iron users. Iron was essential to their ships, to their agriculture and war, to their cooking, it was a part of their lifestyle. More southern cultures in Europe might produce iron and steel in greater quantities, with more efficiency and better quality. But on the whole, the Norse developed an iron working culture which suited their needs.
It was an iron working culture which eventually passed to the Thule. How this culture passed is at times imperfectly understood. What must be appreciated is that later European contact offered metal goods and iron in far greater volumes and quality than the Thule could produce, even with techniques borrowed or inspired by the Norse. Almost overnight, the Norse derived iron working culture was wiped out and replaced. In the west, fragments of copper and bronze cultures persisted locally, allowing us an unbroken continuity and understanding of these metallurgical cultures. In the east, the metallurgical culture is mostly known through archeological reconstruction and reference to literary sources.
But let us begin by examining the metallurgical culture that was available to the Thule. Viking culture identified three sources of iron - mining, bog harvest and trade.
The first was mining and smelting iron ores, this took place in a handful of locations in Scandinavia proper, mostly Sweden. These areas produced surpluses of iron which were used to enforce local hegemonies, or were traded or distributed through and beyond the Norse regions.
However, Norse culture was one of distributed, diffuse populations, centralization did exist, as did trade networks. But by and large, geography and population encouraged regional or local production. Most Norse Iron was produced locally, harvested from bogs.
Bog Iron is a product of rocky country and poor drainage. Geological processes folds edges of continental plates into mountains or fuels volcanoes, which in turn are all slowly worn down. The disordered country formed by mountain building and erosion often produces pockets of poor drainage, filled with silt and stagnant water. In turn, these become hosts for, layer after layer of vegetation, living, dying, living on top of layers of dead matter, dead and decaying layers piling up underneath. In this necrotic stew of stale water, mineral rich silts and dead vegetation, anearobic bacteria thrive.
Some of these bacteria, as part of their metabolic process, end up processing mineralized iron and concentrating it in their excretion. Over time, these excretions form iron nodules. Given enough time, the nodules can get pretty big. The biggest pieces ever found were the size of Buicks. Even within short period of a few decades, nodules will grow large enough to harvest. This is Bog Iron, a sort of naturally occurring, organically produced iron. An iron producing bog could be harvested, would eventually regenerate, and could be harvested again in about a generation. The discharges of the bacteria also produced a metallic/oily slick or iridescent sheen to the water which was usually a good indication of the presence of bog iron within.
Some areas are particularly suited to the formation of bogs and bog iron. The ancient worn appalachian countryside of eastern North America. The rocky Cambrian shield of northeastern Canada, Scandinavia and Iceland, the Baltic region.
For the Vikings the advantage of Bog Iron was that it could be locally produced. All it took was time, labour and a reasonable set of skills. Bog Iron production didn’t produce huge amounts of Iron. But Vikings were frugal, an average Viking household probably owned less than a hundred pounds of iron in total, counting utensils, farm implements, weapons, fixtures and so forth.
This iron would stay in use for decade after decade, even past a century. The relatively low production, and the relative expense in terms of the time and effort to obtain it, of Bog Iron met the needs of the Norse.
Basically, the Viking requirements for Iron were relatively small, and Iron stayed in use for a long time, so you really only needed fairly meagre production, from local village economies, to account for replacement, repair and expansion.
One consequence of the wide distribution of bog iron harvesting was that the skills of iron working were widely distributed through Norse culture. It’s an exaggeration to say that every Norse man was a blacksmith. But not much of one.
This wasn’t a situation where there was a whole complex of centralized skills - Ore mining, smelting, forging, etc., which was so intensive of time and effort that large scale production and distribution was dominating the economy.
This was all local, the labour of digging up bogs, of harvesting or winnowing out the nodules of bog iron, the gathering of fuel, the firing of forges were all done with community labour, or within site of the community, so knowledge and at least some of the rudiments of skills passed into the community and became part of local lore and knowledge.
Even within a village, there’s some degree of specialization. By inheritance or affinity, certain people wind up in certain roles, they become the leaders or the hunters, the animal doctors, the particular farmers, weavers or seamstresses. The skill or knowledge may be generally distributed but some people tend to gravitate or be attributed to certain tasks.
Within a village, there would probably always be at least a few men accorded the status of blacksmiths, and perhaps a handful who were suitable to try their hands at it. The crew of a longship would carry at least a couple of such men. We have evidence of a bog iron forge operation in Newfoundland, where a group of Norse sailors forged iron studs and washers to repair their ship.
Iceland produced its own bog iron. Ironically, Greenland did not.
Greenland did have areas where bogs existed and bog iron could be harvested, but none of these were near or known to the Greenland Norse. There’s no evidence that the Greenland Norse harvested bog iron locally.
Although there was meteoric Iron at Cape York, the Greenland Norse never reached it on their own. There was Telluric Iron found at Disko Bay, but although the Norse did hunt walrus in this area, but apparently never made use of the Iron there while in the area.
Instead, the Greenland Norse for the most part, obtained their iron through trade. Greenland iron came from Iceland, and later from Norway. Imported iron did not arrive in the form of finished tools, but rather as bars or blanks, which were intended to be worked or reworked on site.
The lack of bog iron in Greenland did not mean that the Greenland Norse lost their ironworking traditions. Ironworking for shaping bars and blanks, or repairing and refitting tools remained a strongly embedded local skill and knowledge. As we’ve noted, there is evidence that Norse harvested bog iron elsewhere in the new world, these Norse would have either been from Greenland, or at least passed through Greenland. So there remained a practical need to preserve the skills to some degree
More than that, lacking local iron, and frequently impoverished, the Greenland Norse were forced to stretch the use of the iron that they had, re-using and often re-forging. In the later part of the colony’s history, as ships from Iceland or Norway became ever more infrequent, as the community fell on harder and harder times, maintaining and reworking the community’s stock of iron became crucial.
Conversely, the volume of iron in the community proportionately increased. As the population declined, iron was simply lost, or worn out, or buried with its owners. But relatively, the decrease of iron was outpaced by the decrease in population.
As a result, knowledge base was relatively well preserved, passed down from generation to generation, through many of the men in the community. Because knowledge was fairly widely distributed in each generation, there was relatively little lost from one generation to the next. It was imperfect, some knowledge, some detail, fell through the cracks, and if opportunity presented, would have to be learned all over again through trial and error or guesswork. But on the whole, substantial working lore remained surprisingly coherent.
Even a young Norseman who was two generations away from anyone who had seen an iron producing bog had a reasonable chance of recognizing and harvesting from one, and with a lot of work and some luck had a shot at being a passable blacksmith. How good a shot? Most of this was oral history and lore within the community, much would depend on how gifted and clever the young Norse was, or how determined.
This was the state of Norse metallurgy that the Thule found - a community with a moderate surplus of iron and iron artifacts, with a significant degree of skill and knowledge in terms of both the practical aspects of forging and smithing and at least a theoretical knowledge of harvesting iron sources.
The Thule had already found and were exploiting sources of iron at Cape York and Disko Bay. However, their technique was limited to heating and hammering, to annealing. Elsewhere, in the coppermine basin, the Thule had learned to crudely smelt copper and were working limited amounts of bronze, but there’s no indication that these skills had travelled outside the local area.
Norse ironwork was effectively a quantum leap beyond the Thule practice.
Initial trading contact within the first few years slowly depleted the local surplus of iron artifacts. After that the flow slowed considerably, and iron was traded only grudgingly out of desperation or at higher exchange rates. The Thule placed an extremely high value on Norse iron, but it wasn’t infinite.
They had their own sources and their own worked iron.
The more significant exchange was of knowledge. Starting with the Thule Shaman known as Grandfather, a number of Norse tales and stories of iron passed to the Thule. Grandfather himself on a series of inscriptions on animal hides includes descriptions of harvesting bog iron, of the film or slick that signified the presence of bog iron, of the Norse forges and in some cases crude but remarkably detailed, half accurate drawings, as well as folk tales, myths and descriptions of objects.
These hides circulated to his Grandson, who copied them and passed them on to other students who copied them as well. The primary effect of these extensive descriptions, at least initially, was to raise the trading price of Norse iron dramatically. This was of relatively little benefit to the Norse, much of their surplus was traded away in the first five years, but of immense benefit to the Ellesmere Trading network which either controlled or had access to much of the Norse iron that had entered the Thule system.
Indeed, the effect on the Norse was predominantly negative. As ‘prices’ rose, exorbitant demand pushed the Norse into parting with more and more. A good knife could command a brace of musk-ox. At times, they stole from each other. Ships were stripped of washers and fittings. Even where there was no particular desire to part, winter’s privations often forced desperate decisions. The increasing value placed on iron appears to have triggered episodes of grave robbing or wrecking of abandoned structures seeking more iron for trade. Nor was this confined to the Norse.
Ambitious and avaricious Thule raided outlying houses, slaughtering whole families for iron trinkets. After several such incidents, the Norse withdrew in on themselves, fortifying and guarding their property. For a time, only Grandfather remained among the Norse, though a half dozen trading settlements sprang up in the region.
Impoverished of iron, several of their boats no longer seaworthy, confined to a smaller area and sustaining smaller herds in that area, the standards of living of the Norse actually dropped. Their ability to sustain a subsistence lifestyle was diminishing. They became more and more dependent on trade and relations with the Thule, now primarily woolen and woven products, forming selective alliances with the friendliest of the Thule groups, and intermarrying to cement alliances and bonds.
There was some rallying. Some of Grandfather’s skin messages refer to young Norsemen sent north to Disko Bay or even Cape York to work iron. It seems that over a period of years, he had concluded that the although the resources were not there, the skill was. Archeological evidence of Cape York and Disko Bay shows strong evidence of very late Norse settlements - traditional Norse houses, foundries and smelters, forges.
These took place in the context of Thule contact. Thule vegetables and Caribou show up in the middens as primary food sources. Thule artifacts abound. The late Norse settlements in this area seem to have been cooperative ventures.
But relatively few if any Norse women relocated up there. Mostly, it was Norse men, and they either took Thule wives or eventually returned.
Regardless, perhaps as early as a decade into contact, but certainly inside a generation, there was a new surge of fresh Norse iron flowing into the Ellesmere trading network, a surge which seems to have lasted several decades, perhaps a century.
During this period, the apparent Norse presence in these regions fades slowly away. Houses and shelters stop being built in Norse manner, the presence of attributably Norse artifacts evaporates. The Norse over decades simply return home, or remain and are gradually absorbed into the Thule culture and population, leaving only the residue of their skill.
Accompanying the transfer of Norse iron lore, and perhaps accompanied by some of the Norsemen themselves (a controversial assertion), some of the Thule areas began harvesting bog iron and forging it themselves.
Starting roughly around 1450, we see Bog Iron workings developing in several places in Labrador/Quebec and around Hudson Bay and even some parts of Baffin Island. While we can’t rule out the presence of Norsemen, many of these sites show a certain diversity and improvisation of techniques which suggest that local or regional Shaman’s were acting or inspiring based on the written descriptions of Grandfather and others. Certainly by this time, literacy had become extremely widespread among the Shamanic times, and Grandfather’s original messages and descriptions had been copied and recopied hundreds of times.
There are a number of extant copies of hide markings copied from Grandfather which describe the Greenland Norse tales of bog iron.... ironically, something which most of the Greenland Norse had never seen... Describing the water slicks which marked the presence of iron, and with instructions or discussions of varying detail for harvesting and forging. There’s often loss of transmission or interpretation errors in many of these copies. But there is often enough there to at least be the basis of systematic trial and error to develop a bog iron harvest or foundry.
In addition to the writings of Grandfather and others, we must also acknowledge the likelihood of verbal or oral transmission, particularly given the existence of mixed Thule/Norse ironworking colonies at Disko Bay and Cape York.
Nor can we ignore the possibility that at least some Norse smiths might have ventured out of Greenland into the Thule realm. Labrador Thule folk tales record at least one such man, although he may be an apocryphal figure along the lines of Paul Bunyan of Joe Majurak.
There’s a great diversity of Forges and Furnaces in development use around this time, and classical Norse furnaces identical to those used in Greenland do show up, but clearly in many cases, what we’re seeing is local improvisations.
In some cases, local furnaces are repeatedly torn down or abandoned and rebuilt, indicating an ongoing process of trial and error, or perhaps new information coming in from outside.
By about 1500 or thereafter, there are consistent, more or less standard, designs and modes for furnaces, which show a clear Norse influence, but the likelihood is that the influence is cultural, and almost certainly not the product of Norsemen directly.
It would take at least another generation or two for the Norse influenced furnace and forges to be widely adopted by the bronze and copper producers of McKenzie Bay and Alaska.
Norse derived ironworking spread through the eastern part of the Thule realm. Bog iron working proliferated in Quebec and Labrador, traditionally the poorest and most isolated areas of the Thule realm. It was also well established among Thule on the Hudson Bay coast, including the founder culture spreading inland in some areas almost to the coppermine basin.
The spread of bog iron working seems to have been actively opposed by the Ellesmere trading network, which controlled the Disko Bay and Cape York sites. Indigenous bog working was a threat to a potential monopoly on the control and distribution of iron. For a time, the Ellesmere network resisted carrying bog iron, denounced it as inferior. On some occasions, tensions were such that communities in Labrador or Quebec would conceal their bog iron when Ellesmere traders were around.
Disko and Cape York iron dominated Greenland, Ellesmere and Baffin Island, were actively sought and traded in the western archipelago, and competed with bog iron, copper and bronze on the mainland. Artifacts from the Greenland sources have been found as far out as Siberia.
It is often fashionable to draw a line between the ‘Iron Thule’ and the ‘Copper/Bronze Thule’ and it is somewhat accurate. Notably, the Copper/Bronze Thule tended to be highly conservative and resisted iron. Economics played a part, copper/bronze originated in the west, iron originated in the east, each was relatively cheaper in their own home areas, and relatively expensive to import.
Nevertheless, there was some overlap. The Western archipelago, despite its relative poverty and thin population had a mixture of metals imported from the two subcultures. Copper/Bronze shows up across the mainland down to the coasts of Hudson Bay. Iron artifacts appear in the McKenzie basin, and even some iron workings. Indeed, in the McKenzie basin, we see some experiments mixing iron and tin, creating very crude steel.
Siberia is an interesting case. Most of the Siberian Thule’s imported metals were copper and bronze, mostly from Alaska, but with some from the McKenzie basin. Only a handful of iron artifacts made their way out there, and most of these were Greenland iron.
But then around 1500, we begin to see bog iron production in areas of Siberia. Some of the production is in unmistakably Labrador styles. The technology has essentially leapfrogged half the continent. Whether this is a factor of the spread of literacy and the work of an innovative Shamanic class, or whether some eastern Thule were ending up in Siberia and bringing the skills with them is a matter for debate which may never be resolved. The consensus is that there may have been a mixture of the two.
Siberian bog iron production proved a boon to the Bering Thule, allowing them initially a military advantage over their rivals, the Chukchi and Yakut, and later a trading opportunity. Traded or captured Siberian bog iron artifacts made their way as far south as Mongolia.
Iron culture in the East persisted well into the 1650's, at which point the fur and roseroot trades began to introduce increasing amounts of finished European metal goods, particularly steel axes. After 1700 Greenland production from Cape York and Disko Bay tails off dramatically (although it was never quite abandoned), and we see evidence of the abandonment of bog iron works throughout Labrador and Quebec.
Despite bog iron works persisting in a few areas into the early 1800's, these are rare exceptions, local traditional or cultural activities, and European replacement has been complete. There is, for instance, an elaborate written description from Ungava of a local village’s harvesting and forging of bog iron, the pieces of which are hammered into ornaments of various sorts and given away... The community using a great quantity of imported European metal for just about every purpose.
The fate of Siberian bog iron culture would be the same as the Eastern Iron culture - supplanted by superior iron and steel from European trade. But due to rather more complex and violent relations with the Russians, this took longer. As late as 1800, Siberian bog iron remained a persistent local working in many areas.
Iron among the Thule precedes the Norse interchange. Cape York and then Disko Bay were already introducing small amounts of crudely worked iron artifacts through parts of the Thule realm.
What the Norse interchange did was dramatically increase the amount of iron among the Thule, and offer a slate of new technologies for obtaining and working that iron. An innovation which reshaped many Thule subcultures.
Despite this, iron among the Thule remained at relatively low volumes and relatively crude. A Thule family in labrador might own perhaps a few dozen pounds of iron, a village a few hundred pounds. This is relatively trivial compared to late iron age societies like the romans or the greeks. Although the Thule became relatively sophisticated within the limits of their technology, most of their iron was wrought or hammered, there’s little evidence of casting. There was no chance of such activities as forging gun barrels, and they simply could not compete with European metals when these were introduced.
The iron culture that the Thule adopted from the Norse was effectively living on borrowed time from the day they got it, enduring for three centuries before almost vanishing.
