QuoteAnd of course it is Icelandic, since it is what comes closest to what they spoke in the Viking Age.
Hello.
After more investigations, I believe the Alter messages are written in the old norse language: "Havamal" and not Icelandic - even that Icelandic is still the closest you, today, can come with how they spoke in the Viking Age.
Havamal is the same language as the "Edda Verse" Valnir Rok has on the website.
It would probably also be how the Gods would speak.
