This text analyzes the historical and philosophical concept of death as a transition, a theme deeply rooted in ancient myths and subsequent theological traditions. The primary focus is the figure of the Greek ferryman Charon, who transports the souls of the deceased across the river Acheron to the underworld. This metaphor emphasizes that death does not represent a simple cessation of consciousness or a definitive end to existence, but rather a demanding process of transformation. In these traditions, the transition is understood as conditional and requires the fulfillment of specific ritual obligations, such as offering a coin as payment for passage. If these conditions are not met, souls are condemned to wander indefinitely at the boundary between worlds. The study traces the development of this symbolism from classical antiquity through Virgil to Dante's Divine Comedy. Death is perceived here as a journey that necessitates guidance and assistance, governed by its own laws and order. The objective of this abstract is to illuminate how the perception of the end of life evolved into a structured passage between being and non-being, requiring active participation and ritual preparation, thereby granting death a meaning that transcends a mere biological event.
