This volume from the well known early 20th century creation series is a work comprised of two basic topics- the Aztec and the Incan religions. It speaks of the rituals and deities of both, and compares them at times with Christianity. The linguistic nature of parts of the religious structure especially among the Aztec is frequently pointed out.Indeed the first chapter also speaks of Nordic religion, the separation in ritualism between most Northern tribes and their counterparts in Mexico and Peru, and refutes a few of the theories of the era regarding European influence prior to Columbus.
