Archaeologists have discovered an unusual sword in Denmark—its uniqueness lies in the fact that it may be one of the earliest iron artifacts.

This is reported by livescience.com. The long bronze sword, bent in the shape of an S, was found in a bog northwest of Denmark's capital, Copenhagen. According to the archaeologists, the sword is approximately 2,500 years old, dating back to the late Bronze Age.

Experts also note that this sword was part of a ritual sacrifice.

In addition to the curved sword, archaeologists unearthed other Bronze Age artifacts, including two small bronze axes, several large bronze "ankle rings," and an object resembling a fragment of a needle.

The handle of the bronze sword contains two iron rivets, which may represent the earliest iron ever found in Denmark. Scientists describe this sword as "almost a physical manifestation of the transition from the Bronze Age to the Iron Age."

The leader of the archaeological team, Emil Winter Struve, noted that this sword is a very rare find.

Previously, "The Telegraph" reported that archaeologists discovered a 2,000-year-old bust of Cleopatra. It is considered the most accurate depiction of the queen.
