Maritain, early Greenland colony

I just read Viking Settlers in Greenland and their Descendants During Five Hundred Years, by Poul Noerlund. This is an anthropological study based on archeology of the two settlements. It was written in the 1930s, and it paints a sad picture of a people who became cut off from Europe and died out from all the diseases of malnutrition. One settlement was weakening when it was attacked by Innu and the settlers killed by burning their church refuge over their heads. (There is plenty to show the animosity and cruelty was mutual.) The other settlement died out slowly, with bone malformations preventing childbirth and growth so stunted the average woman was only 4 ft 6. People's teeth were worn down from eating low quality grain, they were iron-starved (heads of axes were fashioned from bone), and of course their were abandoned to their fate by the colonial power, Norway-Denmark, when the Little Ice Age meant the fjords filled with ice became impassable. The Church also abandoned them as the weather deteriorated. It is an ugly memory, right up there with the Irish potato famine, in terms of white-on-white colonial neglect causing death. I read a trashy novel in French, Dole Rumen's Lys d'or, a novel about an art trader in China. It is short and has none of the telling detail a good novel has. I also finished off the complete works of Jacques Maritain. I didn't think his wife's journals were worth publishing, and they were not insightful, although this is not to say the person didn't have merits. It was just a list of headings about when she prayed, and whether she felt arid or transported. She doesn't explain what aridity or exaltation means. The rest of the work is fairly good. I feel at the end how I felt from the start. He would have been more effective if he didn't constantly judge other religions to be inferior to Catholicism. I also thought what a great contribution it would be to look at the impact of Christianity on philosophy in various ways, but also how little he actually does that.
