The term warrior priests is usually used for armed priests of the antiquity and Middle Ages, and of historical tribes. Cerro Sech穩n is an archeological site in northern Peru, dating to 1600 BC. There are several buildings, made from clay and stone. The most striking feature of the temple is its lithic block facade decorated with reliefs representing warrior-priests (wearing a weapon or scepter) and mutilated bodies(heads, limbs, eyes skewered, intestines, vertebrae and viscera). The etched bas-reliefs number approximately 300. There have been various interpretations of the stone carvings. One interpretation is that of battle scenes, carved to commemorate a great battle, with foreign victorious warriors and defeated Casma people. An alternate theory is that the site was a laboratory for anatomical studies, which explains the explicit exposure of different parts of the human body, such as organs and bones. Yet another theory is that it represents a popular bloody rebellion, crushed by the ruling elite. The Casma/Sechin culture (3600 - 200 BC) of Peru refers to the large concentration of pre-historic ruins in the valleys of the Casma River and its tributary the Sechin River and along the nearby coast of the Pacific Ocean.
