Some findings are significant. The article never suggested that they were rewriting historic by their analysis, but it certainly suggested that there is an interesting method of confirming the historical text that had been available. For instance, it is very interesting that apparently their diet was high in protein. That suggests a significant level of wealth, and absence of overpopulation, and a tendency to be restive if there was, in fact, any reason to dissent. Suppression of a protein diet is a common means of oppression.
The meat and dairy products available to the residents surely varied across the centuries. The article does not date the specific finds.
A nice feature of feudalism is that if there’s a shortage of food/peasant ratio the nobility had two factors, instead of just one, that they could adjust.
Cabbage can take up to 180 days to mature and in the absence of insecticides, would need to be carefully tended. It grows best at 60 degrees, bolts at 80 degrees, but prefers full sun to shade. Seed can germinate down to 45 degrees but the best return on seed germination is between 65-75 degrees, same as leeks. Both leeks and cabbage require heavily composted soil and consistent watering but not too wet or they’ll rot. So evidence of consistent cabbage cultivation can give us clues what the microclimate was and lends evidence to a animal population that could produce the manure required for both crops. :)
