 However, linguistic, historical and archaeological evidence suggest that the name could be a borrowing of Aymara "Wila Quta" ("wila" "blood"; "quta" "lake"), due to the sacrifices of camelids that were celebrated at Lake Titiqaqa by pre-Incan Andean cultures that spoke Aymara.Viracocha is often referred to a lord "Tunuupa", which in both Quechua and Aymara have a clear provenance from "Tunu"= mill or central support pillar of a round house and "upa"= the bearer, the one who carries.Thus, "Tunuupa" or "Tunupa" may be read as the "bearer of the mill", while in the Old World the mill or mill stone symbolizes time and the making of time, or "the works that make civilization".
