Collapse_ How Societies Choose to Fail or Succeed - Jared Diamond [148]
Still like Iceland, Viking Greenland was a conservative society resistant to change and sticking to old ways, compared to the society of the Vikings who remained behind in Norway. Over the centuries, there was little change in styles of tools and of carvings. Fishing was abandoned in the earliest years of the colony, and Greenlanders did not reconsider that decision during the four-and-a-half centuries of their society’s existence. They did not learn from the Inuit how to hunt ringed seals or whales, even though that meant not eating locally common foods, and starving as a result. The ultimate reason behind that conservative outlook of the Greenlanders may have been the same as the reason to which my Icelandic friends attribute their own society’s conservatism. That is, even more than the Icelanders, the Greenlanders found themselves in a very difficult environment. While they succeeded in developing an economy that let them survive there for many generations, they found that variations on that economy were much more likely to prove disastrous than advantageous. That was good reason to be conservative.
The remaining adjective that characterizes Greenland Norse society is “Eurocentric.” From Europe, the Greenlanders received material trade goods, but even more important were non-material imports: identities as Christians, and as Europeans. Let us consider first the material trade. What trade items were imported into Greenland, and with what exports did the Greenlanders pay for those imports?
For medieval sailing ships, the voyage to Greenland from Norway took a week or more and was dangerous; annals often mention shipwrecks, or ships that sailed and were never heard from again. Hence the Greenlanders were visited by at most a couple of European ships a year, and sometimes only one every few years. In addition, the capacities of European cargo ships in those days were small. Estimates of the frequency of ship visits, ship capacities, and Greenland’s population let one calculate that imports worked out to about seven pounds of cargo per person per year—on the average. Most Greenlanders received much less than that average, because much of that arriving cargo capacity was devoted to materials for churches and luxuries for the elite. Hence imports could only be valuable items occupying little space. In particular, Greenland had to be self-sufficient in food and could not depend on bulk imports of cereals and other food staples.
Our two sources of information about Greenland’s imports are lists in Norwegian records, and items of European origin found in Greenland archaeological sites. They included especially three necessities: iron that the Greenlanders were hard-pressed to produce for themselves; good lumber for buildings and furniture, of which they were equally short; and tar as a lubricant and wood preservative. As for non-economic imports, many were for the church, including church bells, stained glass windows, bronze candlesticks, communion wine, linen, silk, silver, and churchmen’s robes and jewelry. Among secular luxuries found in archaeological sites at farmhouses were pewter, pottery, and glass beads and buttons. Small-volume luxury food imports probably included honey to ferment into mead, plus salt as a preservative.
In exchange for those imports, the same consideration of limited ship cargo capacity would have prevented Greenlanders from exporting bulk fish, as did medieval Iceland and as does modern Greenland, even if Greenlanders had been willing to fish. Instead, Greenland’s exports, too, had to be things of low volume and high value. They included skins of goats, cattle, and seals, which Europeans could also obtain from other countries but of which medieval Europe required large quantities to make leather clothes, shoes, and belts. Like Iceland, Greenland exported wool cloth that was valued for being water-repellent. But Greenland’s most prized exports mentioned in Norwegian records were five products derived from Arctic animals rare or absent
