This head of a stele statue was discovered in 1996 at Calamazza , in the woods to the south of the town of Aulla(MS) ; it was lying on the ground near a ruined farmhouse . The spikes and the shape impressed in the mortar above the door lintel show where is was lodged . It belongs to the B group and probably dates to the Eneolithic Age ( between 3400/3300 and 2300/2000 b.C. ) . The outline of the head is a low arc with lateral elongations ; the head is rather damaged and is connected to a rectangular -section neck ; on the right side there is part of the shoulder . The barely distinguishable face is circular and slightly in relief .
