The importance of language and bilinguality in the development, perpetuation, and "degeneration" or change of culture is a central theme throughout this treatise. Original pictorial representations of Mayan hieroglyphic sculpture are included as examples, and represent artistic styles and language variations of written Cholan and Yucatec. Modern Cholan and Yucatecan languages are important in the decipherment of Mayan hieroglyphic writing, because these two languages were the languages of the ancient hieroglyphs. Bilinguality as a positive factor Is considered in the florescence and duration of the central lowland Mayan area. The impact of Spanish language on indigenous languages of Mesoamerica is traced from 1519 to the present. Special consideration and speculation is given to the role of Yucatec and Chol as "divine" non secular languages in the florescence of Mesoamerican cultures. This thesis is a continuation and development of undergraduate anthropologic field work undertaken in Mesoamerica during the 1970s. / Graduation date: 1994
