Sheep Among the Thule
What became the Thule sheep was derived from Greenland, which itself was a sub-population of the emerging breed of Icelandic sheep, which in turn was derived from the Norwegian Spelsau variety, an archaic form of the class of North European sheep breeds.
Domesticated sheep run from 45 to 100 kilograms, roughly 100 to 250 pounds. Their fleece is white, but will also come in a range of colours from browns, to greys to blacks. They are generally horned.
Males and Females will become reproductively capable as early as five to seven months, although full maturity takes about a year. The preference is to wait until the second winter before breeding, after which they can breed steadily. Some of the Thule sheep will breed two or three times a year, particularly when breeding is for meat or milk, but usually breeding is annual.
A notable feature of Thule sheep, inherited from Icelandic sheep, is a tendency to multiple births, with twins being common, and triplets, quadruplets and even quintuplets being born.
Of all the Norse domesticates, these seemed most tolerant to the rigors of the Little Ice Age, able to successfully endure harsh temperatures. The super-dense wool of northern european sheep breeds provides effective insulation. The lowest temperature at which a sheep’s body will function normally is about 40 below zero in calm air. They can endure even lower temperatures by huddling together for warmth, or burning through fat reserves, or seeking shelter. So, with some reasonable degree of accommodation - sheds and fodder, sheep could survive in many Thule territories.
The key Thule domesticates, Musk Ox and Caribou, were outdoor animals. So the notion that you would have to keep sheep in buildings from time to time was a strange one. But the Agricultural Thule were by this time living in settled communities, so once the idea as well as the animal was acquired from the Norse it was adopted readily. In some communities, Sheep became an occasional household animal, but as numbers proliferated, sheep lodges were established.
As a collateral effect, sheep tended to be less effective winter feeders than Musk Ox or Caribou, and often required hay or forage to be provided to them. This involved a certain investment of time and effort.
There was a major downside. Sheep carry a virus lethal to Caribou and Musk Ox. Malignant Caterlal Fever (MCF) . This virus affects most domestic sheep and goats without disease. If has been found to be fatal in cervidae species with the exception of fallow deer. It is a virus acquired through nasal and ocular secretions and through the feces. Susceptible ruminants are “end hosts” - ie, it kills so fast and ruthlessly that transmission to other animals in the herd is rare. Clinical finds are reported to be sudden death in acute cases, but more often death is preceded by high fever, depression, enlarged lymph nodes, serious eye and nose discharges, problems with coordination and diarrhea. Deer will often have blood in the feces from prominent intestinal hemorrhage. Death usually occurs in 3 – 7 days. Even today, there is no preventative vaccine. Essentially, it’s sheep ebola. The only effective way to avoid infection was to keep sheep separated from caribou or musk ox, or to simply keep sheep out of caribou or musk ox territory.
The tendency of their animals to die horribly on contact with sheep tended to discourage the spread of sheep through the Thule realm. At times, introduced sheep would simply be slaughtered by angry locals. As word spread of the virulence of the sheep disease, local resistance became fierce. It was only in the more marginal and impoverished areas of the Thule sphere that sheep’s wool was desirable enough to overcome resistance.
In sheep areas, Thule herders developed effective techniques to ensure that their Caribou were kept away from Sheep, and without direct contact there was little risk. Dogs became more prominent as pack and draft animals in these areas, due to their immunity and indifference to sheep disease.
One subtle outcome of MCT, however, was that it gave the Thule some degree of experience with managing virulently contagious diseases and asymptomatic carriers. This, along with the experiences Thule’s own trio of transmissible diseases, provided the Thule with a level of cultural insight into disease transmission, and somewhat effective methods for coping with transmissible diseases that were lacking in southern cultures.
These two factors, the need for special measures to support them and the virulence of MCT, actively worked to discourage the spread of sheep through the Thule sphere. But they did spread. Sheep dominated in the lower half of Greenland, on the Eastern coasts of Baffin, and throughout the northern Quebec/Labrador region, as well as being found occasionally on the west side of Hudson bay.
Despite the downsides, however, Sheep had value which encouraged their spread, particularly in the more remote and impoverished areas of the Thule sphere.
As a meat animal, Thule Sheep grew rapidly, and could be ready for harvest within six months, at a weight of 70 to 90 pounds. For meat, harvest could be any time between six months to a year, but depending on need and circumstance, could be slaughtered earlier or later. Generally the animals were preserved to give at least one harvest of wool.
Hides of slaughtered sheep produced a strikingly coloured, and soft leather, sheepskin. On average, a sheepskin runs from six to eight square feet, and was used for small objects such as gloves, hats, bags, etc., although it could be sewn together to form blankets, or sewn to heavier leathers from caribou or musk ox.
Thule Sheep were also milk producers. Sheep produce milk after giving birth for approximately eight to twelve weeks. The lambs can be weaned off after the second week, and thereafter the sheep can be milked daily. Milk production averages 1.5 to 2 litres a day with some animals producing as much as 3 litres. Sheep milk is high in fats and dissolved solids. Although both Musk Ox and Caribou produced milk, the quantities were small in comparison and harvest was difficult. It was with sheep and among the Sheep subculture that milk production and consumption became significant, and there was a rapid selection for lactose tolerance among these populations, similar to what was seen with Musk Ox subculture.
One relatively unique feature of Thule acquisition of sheep was in the effort to use them consistently as draft and pack animals. This was not unheard of, sheep were used as draft animals in the Himalayan region of central asia. However, the incompatibility of sheep with Caribou or Musk Ox meant that Thule sheep were underwent intensive selection from the beginning for their ability to carry backs or draw loads. This, together with milk production are the principal differences between modern Thule and Icelandic sheep.
One factor contributing to the extensive use of sheep as pack or draft animals, was the use of dogs - a similar sized animal. Sheep harnesses were essentially slightly modified dog harnesses. In a sense, the technology to use sheep effectively as pack animals was already sitting on the shelf. As pack and draft animals, however, sheep were inferior to dogs - they could pack loads between 15 to 23% of their body weight, compared to up to 40% for dogs, and they could not perform in all weather. The difficulties in maintaining adjacent populations of Musk Ox or Caribou, in sheep areas meant that the Thule both embraced higher populations of dogs for labour (and they proved to be effective herders - previously a minor role), and extensive use of large numbers of sheep as pack or draft animals.
The feature which made sheep a successful and valued Thule domesticate was obviously wool. Like Icelandic sheep, Thule sheep have two kinds of wool. The long outer coat of coarse or medium outer fibres, about 27 micrometers in diameter, called Tog, and a finer inner coat of hairs called thel about 20 micrometers in diameter. (In comparison, Musk Ox wool or qiviat is between 16 and 18 micrometers).
In the harsh environment of the Arctic, wool wasn’t necessarily the best item for clothing. Wool isn't very good in the Arctic, its not warm enough and gets soaked too easily. A lot of Europeans searching for the Northwest Passage in OTL died wearing wool for protection. There are stories of them having to literally chip themselves out of bed in the mornings because wool blankets and clothes had frozen solid overnight. Rather, wools became popular for accessory items - lightweight bags, hair braids, tassels, strings, undergarments, summer shirts, scarves and sashes, etc. This was sufficiently valued that wools and woolen items became a major trading item within the Thule sphere.
The Thule adoption of sheep also meant the adoption of weaving and textiles. In turn, this produced a minor revolution elsewhere in the Thule sphere. The Musk Ox subculture of the western archipelago had traditionally been among the most impoverished of the Thule. Effectively, in terms of precipitation, the Islands were deserts. The Islands as a whole were too cold and too dry for even the resilient Thule agriculture, only limited horticulture was achieved with the hardiest of the Thule species. Agricultural techniques were often confined to enhancing forage. The landscapes were too harsh even for Caribou. The result had been a subculture which subsisted on herding Musk Ox and supplementing their lifestyles with milk, horticulture and limited hunting and gathering.
But Musk Ox produced a far better quality of wool, known as qviat, than sheep. It was eight times warmer than sheeps wool, softer than cashmere, significantly stronger, did not shrink in water as sheeps wool did and could last up to twenty years. Prior to the introduction of sheep and textiles, Musk Ox qviat had only local value, mostly as packing and insulation. But the emergence of woolen articles as a valued trade item, and the importing of looms revolutionized the Musk Ox subculture. For the first time, they had something that someone somewhere else might want. Looms and qviat textiles spread rapidly through the western archipelago within a generation.
Musk Ox populations expanded significantly in the south and on the mainland and in alaska, despite the relative vulnerability of these animals to Caribou diseases and adverse conditions. Within two generations, qviat looms and qviat trade had spread to Thule in siberia, resulting in both local trade and exchange, and a trading network that moved siberian qviat from the Arctic siberian coast down across Alaska to the Tlingit and Haida.
In a sense, the intellectual or cultural transfer of knowledge of wool and the techniques and applications for handling it were as significant to Thule civilization as the physical sheep themselves.
Oddly, despite the similarities and common ground between Musk Ox and Sheep subcultures, the two did not overlap. Musk Ox were a non-migratory, sedentary animal that traditionally lived in small relatively isolated herds. As a result, their immune systems were not terribly robust. They were prone to catching and often dying from diseases contracted by Caribou who migrated across large distances in large dense herds. If Musk Ox weren't standing up well to Caribou, then Sheep were death to them. Thule culture learned to develop elaborate systems and techniques for maintaining Musk Ox around other animals, but large scale mingling was simply out of the question.
