Aztecs [PDF ebook] 
A Very Short Introduction

This book presents a very short introduction to the Aztecs using interpretive tools from religious studies and anthropology to uncover the paradox of Aztec life; on the one hand a people highly skilled in sculpture, astronomy, city planning, poetry and philosophic rhetoric while on the other hand a people profoundly committed to cosmic regeneration through the thrust of the ceremonial knife and warfare.
