Rock art in Fenno-Scandinavia can be divided into northern ‘hunter’s art’ and southern ‘farmer’s art’ styles. The distribution of rock art sites shows that ‘hunter’s art’ is found not only in the area where Sami people live today but also across a much more extensive area settled in earlier times by the ancestors of the Sami (Figure 2). The rock art takes various forms, including polished carvings, pecked engravings and paintings made with red ochre. Very often the rock art is found in sites that are associated with water, for example springs, waterfalls, rivers and close to the sea. The commonest motifs are zoomorphs (often elks and reindeer), boats, and anthropomorphs. In this article I will suggest that many of these rock art motifs are direct or indirect representations of the Mother Earth deity known to the Sami as Máttaráhkká.
