In Time and the Ancestors: Aztec and Mixtec Ritual Art, Maarten Jansen and Aurora Pérez present new interpretations of enigmatic masterpieces from ancient Mexico. Combining iconographical analysis with the study of archaeological contexts, historical sources and living cultural traditions, they shed light on central symbols and values of the religious heritage of indigenous peoples, paying special attention to precolonial perceptions of time and the importance of ancestor worship. They decipher the meaning of the treasure deposited in Tomb 7 at Monte Albán (Oaxaca) and of artworks such as the Roll of the New Fire (Selden Roll), the Aztec religious sculptures and, last but not least, the mysterious chapter of temple scenes from the Book of Night and Wind (Codex Borgia).
