The great questions that humanity has always asked itself, while receiving different narratives among the various cultures, bring men together in a universal search for eternity and salvation. In this Dictionary, the writings of Julien Ries are collected in headwords on the theme of life, death and eternity. He traced a path from prehistory to the great religions of the past, up to those still present: Hinduism, Buddhism, Judaism, Islam, Christianity. These headwords are accompanied by the thematic and comparative entries drawn up by Eliade: Eternity, Birth, Afterlife, Death, Descent into Hell, Ecstasy, Free Will, Fall, Reincarnation, Guilt, Salvation, etc. Ries is a precursor of the Eliade’s concept of homo religiosus and on this concept he built the fundamental religious anthropology, which allows us to enter the profound culture that every religion expresses. The themes of life, death and the afterlife lead us to the heart of every religion and every culture, re-proposing the theme of Myth and History (this headwords, written by Paul Ricoeur) of destiny and eternity.
