Piercing blue eyes undimmed by the passing of 1,300 years, this is the Lady of the Mask – a mummy whose discovery could reveal the secrets of a lost culture. She was found by archaeologists excavating a pyramid in Peru’s capital city Lima, alongside two other adult mummies and the sacrificial remains of a child. It is the first time a tomb from the region’s Wari culture has been discovered intact and gives historians the chance to pin down exactly how the pre-Incas buried their dead. The mummy - assumed to be a noblewoman because of the ornate mask - was found in a crouching position surrounded by ceramics and textiles associated with female weavers.
