In the mythology of the Ancient Greeks, Indians, Iranians there are some myths that demonstrate the detailed knowledge of the Arctic regions. They can get their explanation in the light of the concept of the Indo-European homelands [11]. Having gone to the north up to the southern Scandinavia some groups of the late Proto-Indo-Europeans (Funnel Beaker culture - FBK «AB») had the opportunity to observe the polar phenomena directly. The climate changes about 3000 BC made their descendants (FBK «C») return to the Danube-Tissa region where they and the people of Lengyel IV/V culture formed the alliance that can be identified as the Greek-Aryan community that corresponds the co-existence of the archaeological cultures such as Boleraz/Baden +Pit Grave I (with flat-bottomed pots) cultures. Realistic stories about the Arctic regions that were brought by the northern group of Indo-Europeans had become the common knowledge inside this community, and as time went, they were transformed into fantastic tales which had been persisting for more than three millennia as sacred heritage, until they were recorded and included into the literary works of the Ancient Greeks, Iranians and Indians.
