Rock-carvings from Bardal, Nordtröndelag, Norway. There are two layers of carvings on the rock, the oldest one shows natural-size elks and other figures, here painted in yellow, and can be dated to between 7000 and 4000 BC. The later one shows ships and geometrical patterns, here painted in red, and can be dated to the Late Bronze-Age, c. 1000 - 500 BC.
