The document discusses the history and politics of Mexican theater. It explains that playwrights would use Aztec history and figures like Xicotencatl and Tlahuicole to illustrate the mistreatment of the mestizo class by criollos of European descent. Two playwrights, Mateos and Riva Palacio, wrote fifteen dramas and sketches about issues of independence, colonization, and religious zealotry that became foundational to Mexican theatrical thinking. It also describes the 1878 play Quetzalcoatl, which symbolically depicts the marriage of Old World and New World cultures through the image of a feathered serpent holding a cross.
