Death is an intriguing issue, an immense concern in human thought from the beginning of time, a daily, irreversible and inevitable process of becoming; man’s attempts to avoid and transcend it have become a hopelessly eternal struggle. Death leads us to thinking about who we are and creates distress over finiteness, not as an act feared in itself, but for what comes after it. The idea of transcending over time has given man values to calm the uncertainty and to come to grips with the end with places of eternal Rest, The Hereafter, the hope of existence in another place. In the Nahua worldview there were four places, perhaps erroneously called “hells,” destinations determined by the way the individual died: Chichihualcuahco, Tlalocan, the Sun, and Mictlan. Here I will address Mictlan to reconstruct the steps or “underworlds” that the deceased had to pass to reach the final destination in order to show the conception and characteristics of the Mesoamerican “underworld,” and to highlight the differences with Christian conceptions of “hell.”
