Christian Giudice''s Occult Imperium explores Italian national forms of Occultism, chiefly analyzing Arturo Reghini (1878-1946), his copious writings, and Roman Traditionalism. Trained as a mathematician at the prestigious University of Pisa, Reghini was one of the three giants of occult and esoteric thought in Italy, alongside his colleagues Julius Evola (1898-1974) and Giulian Kremmerz (1861-1930). Using Reghini''s articles, books, and letters, as a guide, Giudice explores the interaction between occultism, Traditionalism, and different facets of modernity in early-twentieth-century Italy. The book takes into consideration many factors particular to the Italian peninsula: the ties with avant-garde movements such as the Florentine Scapigliatura and Futurism, the occult vogues typical to Italy, the rise to power of Benito Mussolini and Fascism, and, lastly, the power of the Holy See over different expressions of spirituality. Occult Imperium explores the convergence of new forms of spirituality in early twentieth-century Italy.
