The Passion Play is considered to be part of “folk religion,” supported by clergy but not considered to be liturgy. The Passion Play has antecedents in the plays put on by evangelizers to teach the Catholic faith and to get the indigenous to renounce their former beliefs. However, the passion play incorporates areas which were special or sacred to the pre Hispanic world, including the gardens that once belonged to the emperor Cuitláhuac and the hill on which the New Fire ceremony was performed. The Passion Play started as a number of reenactment events held in a number of places in the borough during Lent and Holy Week, including a procession with the Señor de la Cuevita on the fifth Friday of Lent. However, by the early 20th century, one main passion play for the borough had come into existence. According to one local legend, Emiliano Zapata lent his horses for the 1914 version of the play.
