"The Enigmatic Centaur Head: A Scientific Puzzle"

Despite intensive scientific analyses, the brown film on the centaur head from the Parthenon temple at the National Museum of Denmark remains a mystery. The film, first examined in 1830, contains oxalates, but its origin is unknown. Recent investigations found no traces of biological matter or paint, and the film consists of two distinct layers with different chemical compositions. The centaur head, brought to Denmark in 1688, has been indoors since before modern industrialization, making air pollution an unlikely cause. The mystery of the brown film persists, leaving researchers puzzled.
