A British team of archaeologists on expedition in the Peruvian Andes has hailed as "sensational" the discovery of some of the most sacred objects in the Inca civilisation -- three "ancestor stones", which were once believed to form a precious link between the heavens and the underworld... Dr Frank Meddens, research associate of Royal Holloway, who was also on the expedition, said they had "danced a little jig on top of the mountain" after discovering the objects that they had only read about in 16th-century Spanish documents.
