Poetry written for the Day of the Dead are known as literary calaveras, and are intended to humorously criticize the living while reminding them of their mortality. Literary calaveras appeared during the second half of the 19th century, when drawings critical of important politicians began to be published in the press. Living personalities were depicted as skeletons exhibiting recognizable traits, making them easily identifiable. Also, drawings of dead personalities often contained text elements providing details of the deaths of various individuals.
