L’art rupestre d’Alta, Norvège. Sémiotique visuelle

Abstract

Alta rock art shapes appear remarkably similar over a period of nearly six millennia. Careful observation reveals graphic variations that give the shapes a distinctive appearance. After defining these variations, we subjected the data to multiple factor analysis in order to highlight the similarities between certain groups. The results interpretation confirms the four phases of representation defined elsewhere and allows us to link altitude, dating and engraved groups. This study also offers the possibility of comparing the engravings with other decorated panels, and indicating the possible phases of activity in these areas. We also consider the modest rock paintings of Alta.
