Johann Joachim Winckelmann (1717-1768), the famous German archaeologist and art historian, wrote in his notes: "Of all the works of antiquity that survived destruction, the statue of Apollo represents the highest ideal of art”. Even Michelangelo would stop in admiration before the Apollo of the Belvedere, studying its volumes and using it as a model. The most iconic statue of the Vatican Museums, dating back to the mid-2nd century AD, is now once again visible to the public after a five-year restoration that ensured the stability and preservation of the masterpiece. In 2019, during one of their periodic inspections, the Vatican team of archaeologists, restorers, and historians discovered that the statue was in serious danger. The condition of the ankles and knees was alarming, and they noticed a worrying structural weakness that required a comprehensive restoration, addressing the loads, anchoring system, and center of gravity. The intervention has successfully restoredan absolute masterpiece to the world.
