"Bulls in defensive position", 5500 years ago

The engraving from the Bull grotto of Kamyana Mohyla in South-Eastern Ukraine. In pictures four bulls staying close to one-another in so-called "defensive position". Due to photogrammetric study and numerous references from Central Asia, this engraving is dated back to Eneolithic — Early Bronze Age of the region (approximately 5500 years ago). Some of the bulls have initially been covered with red ocher or superimposed with a number of cupmarks. The cave is currently unuavailable due to the safety reasons. Source: Objaverse 1.0 / Sketchfab
