How does Vallejo illustrate the theme of existential anguish in the poem, The Black Heralds?

“The Black Heralds” is an excellent example of existential anguish. The poem contains classic descriptions of the existentialist experience: trying to create meaning from a world that has no meaning but is empty and confusing; trying to understand the purpose of an existence that makes no sense; trying to establish the freedom and responsibility of the individual in relation to established ethics and morality; trying to endure the hardships of life when there seems to be no valid reason or reward to do so. Angst is often associated with existentialism because there is so much anxiety, guilt, and isolation that comes with individual responsibility and that stems from unanswered questions about causation and human suffering. A possible conclusion is that there is no meaning to life because there is only a path to nothingness, but Vallejo tells readers that he just does not know what to conclude.
