In the way of summary of the quotes about the Nicholas expedition I would like to make the following points

1) There appears to have been an expedition.

2) The expedition was at least in part a voyage of discovery - this is the whold point of Nicholas' / Cnoyen's book. Rergardless of the truth of what was involved or seen in the expedition, the nature of it is the most core issue.

3) There were Norsemen involved in the expediton. This would not be third hand information to Conyen, but at the very least second hand from Bardson. Possibly Cnoyen was in Bergen when the ship arrived from Greenland.

4) 8 people returned from the expedition to Bergen (see 3).

5) This occurred in 1364.

6) The expedition was purported to have gone beyond Greenland into unexplored regions of the North. There is, of course, the possibility that it only went as far as west Greenland, where Nicholas sat down and made up the rest of the journey, however,

7) Certain aspects of the expediton reported by Cnoyen, seem to fit in with the actual aspects of the region. This could be 'wsihful thinking' - I have laid what I know out, people can make what they will of it in that regard. I note again, though, that Beste, one of the first to sail those waters, believed Nicholas (Cnoyen)'s work to be true and accurate.

8) Nicholas also writes of a 'sucking sea' , which, if true, can only refer to Hudson Bay - he also states that he saw the SW coast of that sea.
I have tried to lay these out in order of probability, that is, point one is the most likely to be true, and should be given more weight than the later points. All of these points fit the scenario outlined in the KRS, and can be looked at as pointing to the veracity of that document.
