The subject of this book is the life of the Mexicans?the Mexica, as they said themselves?at the beginning of the sixteenth century. At that time, in the early 1500s, nobody, from the arid steppes of the north to the burning jungles of the isthmus, from the coast of the Gulf of Mexico to the shore of the Pacific, could have believed that this enormous empire, its culture, its art, its gods, were to go down a few years later in a historic cataclysm.
