Jakarta –
40 Rock carvings or petroglyphs were recently discovered on a former rocky island in Bohuslan, Sweden. These petroglyphs depict objects from 2,700 years ago, such as ships, people, and an animal thought to be a horse.
The prehistoric image is carved on a large granite rock face, as quoted from Live Science. He is more than twice the height of an adult.
Martin Ostholm, one of the archaeologists who discovered these petroglyphs, revealed that the rock was originally part of an island. He estimated, the image was carved while standing on a boat or on an ice mound.
Discovery of Prehistoric Stone Carvings
Initially, researchers wanted to find new petroglyphs in Bohuslan. According to the United Nations Educational, Scientific and Cultural Organization (UNESCO), the city of Bohuslan was previously famous for its ancient stone carvings. One of them is the Bronze Age artwork created at Tanum, a UNESCO world heritage site.
They then found a rock face covered in moss. At first glance, there were man-made carving lines on the stone.
The research team then removed the moss. From there, they found petroglyphs. The pictures vary.
What is surprising is that there is a large carving of a 13-foot or 4-meter long ship. This finding is special considering that most of the petroglyphs there are 30-40 cm long.
How to Make Petroglyphs
Researchers estimate that people in the past made it by banging rocks against granite surfaces. As a result, the white layer underneath is visible.
According to James Dodd, a researcher at the University of Aarhus in Denmark, petroglyphs made in a short time usually tell something. Repetitive images such as ships, animals and people form the narrative.
This rock art is also thought to be a sign of ownership. But until now, the exact function of these petroglyphs is unknown.
