THE ARCHAIC HORIZON 65 



these appear in relation to the archaeological evidences 

 of the archaic horizon. 

 I. Pre-Archaic Horizon. 



The peopling of the New World from Asia 

 by tribes on the nomadic plane of culture. 

 II. The Archaic Horizon. 



Invention and primary dissemination of agri- 

 culture, together with pottery making and loom 

 weaving. Homogeneous culture with unde- 

 veloped religion and unsymbolic art. Practi- 

 cally limited to arid tropics. 

 III. Post Archaic Horizon. 



Specialized cultures in North, Central, and 

 South America dependent upon agriculture 

 Strong local developments in esthetic arts, re- 

 ligious ideas, and social institutions. Agricul- 

 ture extended to humid tropical and temperate 

 regions. 



We will now make an effort to analyze still further the 

 historical levels in the Post Archaic Horizon.
