Lucien Millo has always had a keen eye on symbolism in his works, which he considers capable of leading the Spirit to invisible and inexpressible realms. The study he now proposes is to submit to the initiatory acumen of the reader a symbol that combines pleasure and the highest spirituality: wine. Because it is the happy marriage of the earthly and the divine, at the precise intersection between the gift of nature and human craftsmanship, wine thereby conceals mysteries that Freemasons must discover. In a highly documented essay, the author examines the theme of wine through various approaches, whether philosophical, poetic, theological, and of course, initiatory, to explain the place of wine in the Masonic journey. As a blend of the profane and the sacred, wine gradually reveals itself, under the pen of Lucien Millo, as one of the deepest and most joyful symbols of Freemasonry.
