 The sacrifice took place on a platform on the summit of the volcano and was presumably intended to calm the mountain spirits during an eruption of the neighbouring volcano Sabancaya.The mummies were discovered in 1995 by Johan Reinhard and colleagues on the summit of the mountain.Such sacrifices with children being the usual subjects are known as "capacocha" and the discoveries of their mummies on mountains in the Andes has gained them a lot of attention.
