I was translating some Old Norse and came across the word 'hagr' which has little to do with the cartoon since the word as an adjective means 'skilful' and the noun has even less to do with the Viking bumbler.
Hagar has been with us since 1973. When the original cartoonist, Dik Browne (who bore a slight resemblance to Hagar) died, his son, Chris Browne, continued the cartoon. It is a funny look at Vikings in the later part of the first millennium. Hagar raids castles but he does not seem to raid small villages or sell people into slavery like a real Viking. That would not be at all funny.
I found a website with 3,450 strips to look at. I like Hagar so I recommend it. http://www.hagarthehorrible.net/
