This massive artifact is believed to be more than a simple ancient structure. It is believed to be an ancient star chart used in agriculture over 3,000 years ago.
The Rupinpiccolo is a defensive structure surrounded by a massive wall 3 to 7 meters thick, in use since 1800 BC. to 400 BC It is considered one of the best examples of well-preserved castles in the Karst region.
However, with the discovery of two mysterious stones at its entrance, many mysteries were added to the history of this place.
After carefully examining one of the stones, researchers identified 29 mysterious carving marks – five on one side and 24 on the other.
According to archaeologist Federico Bernardini and astronomer Paolo Molaro of Italy’s National Institute of Astrophysics, these marks were likely created with a chisel by a single craftsman.
Researchers speculate that the carvings on the stone represent bright stars, especially those in the constellations of Orion and Scorpius. These stars rose in the eastern sky during the “protohistoric period” during an event known as the “heliac rising.” One of the stones, according to experts, could even depict the Sun.
Astronomer Molaro emphasized that the scale, statistical accuracy and orientation of the marks support the idea that these are stars.
According to Molaro, the use of bright stars as landmarks in agriculture was quite common. Even in the 8th century BC. the Greek poet Hesiod described the heliacal rising of stars such as Orion and the Pleiades as an important aspect of crop planting.
However, not all experts agree with this statement. Astronomer Ed Krupp of the Griffith Observatory suggests that any connection between the marks carved into the stone and the brightest stars could be mere coincidence.
Research by Bernardini and his colleagues was unable to explain the mysterious 29th mark engraved on the surface of the stone disk. This mark, found next to a supposed image of the constellation Orion, does not correspond to any known star.
The most intriguing aspect of this claim is that the 29th mark may represent a supernova that was visible when the disk was created but later disappeared from view. A black hole or supernova remnant could still be in that location today, Molaro said.
Until now, very little is known about the culture of the Kastelleri, a Bronze Age people who built more than 100 fortifications in the ancient region of Istria. The accuracy demonstrated by the star map is surprising and still baffles modern scientists.
