Sarcophagus (from ancient Greek, 'carnivorous') is a massive tomb of stone, wood and other materials, often with ornaments and paintings.
"Sarcophagus of Humanity" is a part of the sculptural-philosophical composition consisting of five items.

Each side of the sarcophagus contains images of revolutions, social conflicts and confrontation of different groups of people. A crowd of revolutionaries, their slogans, their faces hidden behind masks, are against faceless enemies with shields. History shows that revolutions are bloody events where not just both sides suffer, but eventually the humankind itself.
The sarcophagus's lid is a plate with the pictures of state flags of different countries.
