Nynorsk is a much older language than Bokmål and has it's origin in the german languages. Translating the text also involves if it shall reflect the poetic structure or just the context. The first way I translated I made a straight forward Nynorsk translation ("the language of the vikings" is not known as a poetical language directly).
When you did your remark I read the English translation. I included the earlier title in the text material, excluded definite form of "love" as in the French. I avoided to use nouns in different genus, which is common in Nynorsk.
