KANSK, RUSSIA—Siberian archaeologists have completed their study of a skull belonging to a man who died between the ages of 30 and 40 that was discovered last year at a Bronze Age burial ground in the region of Krasnoyarsk. The Siberian Times reports the skull bore obvious traces of trepanation, or brain surgery, which in ancient times was carried out for both medical and ritual reasons. In this case, the researchers suspect the trepanation was likely medical in nature, and that although the patient survived the surgery and lived for a time afterwards, he may have died because of post-operative inflammation. In reconstructing the incisions made in the skull, the researchers suspect the "surgeon" had an assistant helping complete the procedure.
