The region of northern New Mexico and southern Colorado holds a unique place in the world of Spanish folk literature. Isolated from the rest of the Spanish-speaking world for most of its history since its first settlement in 1598, it has retained, even into our own time, much of its Hispanic folkloric heritage from the sixteenth and seventeenth centuries-ballads, songs, poems, folktales, sayings, anecdotes, proverbs, riddles, and folk drama. In this book, written in the late 1930s and never before published, Aurelio M. Espinosa, New Mexico's pioneer folklorist, presents the first comprehensive, authoritative account of the relict folklore, bringing together the results of his collecting during the first third of this century, in the Southwest and in Spain, and his many ground-breaking scholarly studies.
