A representation of a fawn carefully engraved on a small piece of slate with a silex burin. Some 10,000 years old ―if not more― , it is one of the oldest and most beautiful examples of prehistoric decorative art found in our country. It was discovered on the 26th December 1932 by the prehistorian Salvador Vilaseca who, with his collaborator Manel Mata, took advantage of a day off to excavate the area around the rock shelter of Sant Gregori. The piece is exceptional, according to its finder, “for its artistic expertise and the expressiveness with which its creator has endowed it”.
