Very Old Signs Indeed

Bronze Age petroglyphs (rock carvings) at Tanumshede on the Swedish west coast. (Photo taken by me in the early 1990s.) In total there are about 3000 petroglyphs in this area, occurring in about 100 panels along a 25 km stretch, which was the coastline of a fjord during the Bronze Age (roughly 1800 to 600 BC). The Scandinavians of the Bronze Age were sophisticated woodworkers and travelers by water. Some of the glyphs depict long boats carrying around a dozen passengers. Wagons or carts are also depicted. Other scenes depict people hunting or performing agrarian tasks. The rock carvings are endangered by erosion due to pollution. They have been painted red to make them more visible for tourists.
