The bio-anthropological studies allowed us to know that the Lady of Cao died when she was approximately 25 years old and that her height was of 1.48 meters. Moreover, the study of her hair allowed us to know that she consumed corn grains and seafood.
But, who was this woman? The insignia of power that accompanied her (crowns, diadems, bludgeons, nose-pieces, ear-pieces), if they were used by the personage, would suggest her privileged status within the hierarchical composition of the Moche society of lower Chicama.
It is surprising to see the similarity between her insignia and those of personage D from the so-called «Sacrifice Ceremony», a central theme of the Moche iconography, which is also shared with the evidence coming from the Lord of Úcupe, from the neighboring valley of Jequetepeque.
In the narrative sequence of this ceremony, the blood of the executed prisoners is offered to the highest dignitary. The archaeological research has allowed us to identify these personages in their own tombs: personage A, to whom the cup of blood is given, corresponds to the position occupied by the Lord of Sipán; personage B corresponds to the Owl Priest, also buried in Sipán; personage C corresponds to a priestess whose tomb was discovered at San José de Moro; and personage D is compared to the Lord of Úcupe and to the Lady of Cao. Thus, we recognize his semi-divine investiture and political-religious authority.
The presence of tattoos on the body, with figures of snakes and spiders (both animals linked to the fertility of earth and water) and other elements linked to the magical-religious, suggest that the Lady dedicated herself to very deep spiritual activities associated to curanderismo (folk healing).
