An unexplained object was found in an ancient temple. In southern Bulgaria, in an ancient Thracian temple on the territory of a fortified settlement, a 2500-year-old bronze object was discovered. The design looks like a ring on which four hooks are attached. However, behind the outward simplicity hides a question that archaeologists have been struggling with for several weeks: no one can say for sure what this item was for. Scientists are calling the discovery unlike any other. And that is her mystery.
