First, please look at this thread: History of Aryans in Europe
As you read here, the first mention of Cimmerians in western sources is in The Odyssey of Homer (11.14), where they are described as inhabitants of the opposite side of the Oceanus river surrounding the earth, a country forever deprived of sunshine.
If we consider sound changes in the Germanic languages (k>h), the original land of ancient Cimmerians could be Himmerland in Denmark. There are enough evidences that these Cimmerians first migrated to the northwestern part of Black sea and in the 8th century BC they conquered northwest of modern Iran and eastern Anatolia, and in the 7th century BC they founded the Achaemenid dynasty.
