A bull and two boat at Aspeberget. The shape of the larger boat indicates that it was made in the beginning of the Bronze Age. The bull can also be dated to the start of the period. Scholars have argued that the bull was introduced as a rock art symbol in Scandinavia as a result of impulses from eastern Mediterranean, where the bull was an established ritual feature. This theory is supported by the fact that some of the early Bronze Age metal objects found in Scandinavia are made from copper ore mined on the island of Cyprus. Another interesting detail is the curly extensions on the stem. These lines are much narrower and shallower than the rest of the boat and was carved at a later date. The boat have consequently been updated during the Bronze Age to follow the changing ideas on how rock art boats should be presented. Yet another fascinating thing is that that the small boat was made at the end of the Bronze Age, perhaps a thousand years after the large boat came into existence. That is one long lived tradition!
