Nacimiento fuses the history of the birth of the mestizaje with the emergence of Christianity and Christmas in the New World. It explores pre-Hispanic rituals and the impact of colonization on the Americas. Nacimiento examines stories of La Malinche, Juan Diego and the Virgen de Guadalupe, and other historical characters whose stories are seminal to the identities of the New World. Act II of Nacimiento demonstrates the festive nature of how Mexican Christmas traditions are celebrated today in Mexico and in North America, through the Posadas: celebratory dances and retelling of the Nativity scene.
