"Italian scientists Monday collected from a small chapel bones that are presumed to be the remains of celebrated Renaissance artist Caravaggio who died 400 years ago," reports AFP. The scientists, watched by media, retrieved the bones from an ossuary in the central port town of Porto Ercole to find out more about Caravaggio's death and give him a more notable burial site. The remains were placed in aluminium boxes and taken to the University of Bologna's Ravenna campus where they are to be compared with those of descendants of the artist's family. Criticised at the time for an expressionist style, Caravaggio works stirred religious debate.
