This research paper analyses two short stories, “Bon Voyage, Mr. President” and “A Very Old Man with Enormous Wings” by Gabriel Garcia Marquez, using Heidegger's concept of authenticity. The paper argues that the characters in both stories, “Bon Voyage, Mr. President” and “A Very Old Man with Enormous Wings”, are driven by their old age and a heightened understanding of mortality. This understanding of death leads to a sense of authenticity as the characters are forced to confront the limitations of their existence and re-evaluate their priorities. Through an analysis of key scenes and character development, the paper demonstrates how the concept of authenticity is central to understanding these stories and the characters within them. Ultimately, the paper concludes that Heidegger's ideas provide a useful lens through which to interpret Marquez's work, highlighting the importance of authenticity in the human experience.
