Many people in Iceland talk about trolls as nasty or evil ogres, plagued with a seemingly endless aggressive streak. But others will tell you that these are untrue and shameful images that say more about the ignorance of the storyteller than about the trolls themselves. Yes, trolls are quite large and tremendously strong, but by nature they are essentially peaceful cave-dwellers who only come out at night. The reason they are nocturnal is that if they are touched by the rays of the sun they will turn into volcanic statues. In fact I saw many of these unfortunate creatures while on our recent trip to that most interesting island, which is east of Greenland and south of the Arctic Circle.
Actually Iceland and Greenland are misnamed, because most of Iceland is green, and almost all of Greenland is glacial ice. The common explanation is that the two lands were intentionally misnamed because Icelanders were happy being left alone and so adopted that inhospitable handle, but people in Greenland wanted to lure more tourists and residents with the more enticing name.
