"The Penitente Moradas of Abiquiú" by Richard E. Ahlborn is a scholarly historical account published in the late 20th century that explores the architecture, cultural significance, and socio-religious practices of the Penitente brotherhood in Abiquiú, New Mexico. The book delves into the unique "moradas," or meeting houses, that serve as essential sanctuaries for the Penitente community, showcasing their traditions rooted in Hispanic Catholicism, particularly during Holy Week observances. In this comprehensive study, Ahlborn documents the architectural features and interior artifacts of two distinct moradas, illustrating how they reflect the cultural heritage of Spanish-Americans in the region. The book examines the organization of the Penitente brotherhood, its practices of penance and mortification, and their ceremonies such as the dramatic "tinieblas," which symbolize the Passion of Christ. Through photographs and historical descriptions, Ahlborn emphasizes the significance of these moradas as vital records of Hispanic traditions and social structure, offering insights into the continuity and adaptation of these practices amidst external threats to their cultural identity.
