The success of my revised edition of Mr Crawley's The Mystic Rose has encouraged me to bring together in the present volume some of his papers previously unpublished in book-form, on subjects akin to those of his great work. Mr Crawley's treatment of these problems of sexual anthropology, especially on the psychological side, was, in the years in which he was most actively at work, too uncompromisingly original to meet with general acceptation, even in academic circles. But now his standpoint, which can perhaps be best described as being that of a profound psychological analysis on the basis of biological common-sense, is beginning to be appreciated. And the following papers will be found, I think, to contain all those qualities which so sharply differentiate Mr Crawley's work from that of most other students in the same fields.

Lewis Henry Morgan (1818-1881) was America's leading ethnologist in his day, & his scholarship played a role of exceptional importance during the critical period of the 1860s-1880s when anthropology was beginning to crystalize as a specialized field of research. Contents of this vol.: Lewis Henry Morgan & His Library; Morgan's Life & Works; The Library & Its Contents; Analysis of the Collection; Explanation of the Inventory, Catalogue, & Register; Bibliography of Morgan's Publications; The Inventory; The Catalogue; & Register of the Morgan Papers.

As the Olmec culture developed in the early pre-classic period, we observe the phenomenon of the Olmec Heads and their Mysterious origins. Through ideological management and coercion mechanisms, the dominant ruler appears and alludes to forms of government exercised by individuals. Massive sculptures and large-scale architecture represent the first representations of political power. The socio-political complex that developed thus encouraged the development of similar forms in other areas of Mesoamerica, resulting in the first stratified societies consisting of actual states, as seen in Teotihuacan in the Mexican highlands, Monte Albán in Oaxaca, and the Maya city states during the classical period. A corollary of this process was the rise of some post-classical societies that reached supra-state levels, such as the Mexica, who settled in the Mexican highlands and established a true pan-Mesoamerican empire. Following this brief introduction, it is time to examine each ancient Mexican society considered the most significant in Mesoamerica's political development.
