This is an intensive study of the folk culture of the village of Chan Kom, located in the north central part of the Yucatan peninsula. The basic presentation is in twelve chapters concentrating successively on the village and its setting; history; tools and techniques; economics; the division of labor; family, village and state; the invisible world; ceremonies of field and hive; the novena and the village fiesta; sickness and its cure; the life cycle; and the meaning of nature. The autobiography of a native community leader is presented as a separate chapter. The six appendices include a diary of his life in Chan Kom by Villa Rojas; some myths, legends, and tales; texts of Maya prayers; notes on midwifery by Katherine MacKay; an analysis of Indian and Spanish elements in the culture; and a glossary of Maya and Spanish animal and plant names mentioned in the text. The original draft of this source was prepared by Redfield and was submitted to Villa Rojas for additions and changes.
