In Ísland, they speak Viking.
That is pretty much true, actually
They are descendants of the old norse, pretty much like the Faeroe Islands. Even more there, actually.
But the language is old norse. And it's really really fucking beautiful. If you haven't heard it (which I think you have as I suspect you speak it) I would recommend the song "Ormurin Langi" by the band "Týr". "Ormurin langi" translates to "The long snake" and was the name of the kings boat. It's a remake of an old "Kved" (and old song/story-telling "method") of originally 86 verses about when the norwegian king the year 1000 had a huge defeat when he met 70+ ships against his 11 ships in open sea. It was a huge battle that depicts some rather cool battle-techniques and of course heroism. Because the king lost (duh), this was the start of christianity in Norway, basically paving the way for the big language fuck-up.
I may, and I probably do, remember most of these numbers only approximately.
