Featuring a small hole for hanging at the top, the mask is hollow inside and was most likely originally suspended from a wall, archaeologists believe. They added that such masks are unquestionably linked to theatre, whose patron deity was Dionysus.
The head of the Dubrovnik Archaeological Museum, Domagoj Perkić, noted that most of the finds were uncovered in the entrance and side section of the cave, which had been almost completely concealed and buried prior to the excavation.
Other fragments of Greek pottery were also discovered in the Crno Jezero cave, including some of the finest and most valuable vessels of the period, which were used either for storage (amphorae) or for drinking wine (various types of cups).
Research conducted in 2025 established that the cave and certain parts of it were used during different periods, from the Bronze Age to the end of the Late Iron Age, although for different purposes.
