Researchers working in western Sweden made a fascinating discovery. Scientists have found about 40 petroglyphs in the area dating from around 2700 years ago. Petroglyphs can be used for digging, carving, etc. on rocks. Shapes created by methods are called
One of the researchers, Martin Östholm, told Live Science that the petroglyphs were created on the face of a granite rock that used to be part of an island. This too, Östholm added, may have required people to stand atop a ship or a platform built on ice to form the shapes.
Petroglyphs depict people, ships and animals
The petroglyphs, which are reported to belong to thousands of years ago; It depicts things like ships, people, and animals. In addition, four-legged creatures, which are thought to be horses, can also be encountered. The largest of the figures is a petroglyph, 4 meters long, depicting a ship. Normally, most of these shapes range in size from 30 to 40 cm, archaeologists say.
Saying that his research continues, Östholm states that people created the petroglyphs to hit hard stones on the granite rock face. In this way, he adds, the underlying white layer is exposed and can be seen from land or from passing ships.
It is not known exactly why the petroglyphs were made; however, according to some researchers, people may have done such things to mark their property. On the other hand, other scientists think that petroglyphs may have been created for purposes such as storytelling.
The discovery was made in Bohuslän, Sweden, where such findings have been found before. Researchers looking for petroglyphs came across some lines that appeared to be man-made when they encountered a moss-covered rock. When the moss was removed, the discovered petroglyphs were found. Because the rock was so steep, the researchers had to stand on a platform to access the carvings.
