The Virgin of Guadalupe, though quintessentially Mexican, inspires devotion throughout the Americas and around the world. This study sheds new light on the long-standing transnational dimensions of Guadalupan worship by examining the production of sacred space in three disparate but interconnected locations-at the sacred space known as Tepeyac in Mexico City, at its replica in Des Plaines, Illinois, and at a sidewalk shrine constructed by Mexican nationals in Chicago. Weaving together rich on-the-ground observations with insights drawn from performance studies, Elaine A. Pea demonstrates how devotees' rituals-pilgrimage, prayers, and festivals-develop, sustain, and legitimize these sacred spaces. Interdisciplinary in scope, Performing Piety paints a nuanced picture of the lived experience of Guadalupan devotion in which different forms of knowing, socio-economic and political coping tactics, conceptions of history, and faith-based traditions circulate within and between sacred spaces.
