A whimsical 6000-year-old prehistoric clay mask that depicts an unusual non-human face was found in the ancient salt mines at Provadia-Solnitsata in northeastern Bulgaria during excavation. The mask depicting an unknown mythical creature is well-preserved. It is made of clay. Researchers believe that it was made in the 5th millennium BC.
According to archaeologists, Provadia-Solnitsata was inhabited by some of the world’s first rock salt miners in the Neolithic era. Over the past few years, many finds have been unearthed in the area, including golden artifacts.
According to the head of the archaeological expedition, Prof. Vasil Nikolov, the artifact was found at the site of the prehistoric settlement, which is the oldest salt production center in Europe, dating back to between 5500 and 4200 BC.
