Occult Imperium: Arturo Reghini, Roman Traditionalism and the Anti-Modern Reaction in Fascist Italy is a book by historian Christian Giudice published by Oxford University Press in 2022.

[6] Historian Mark Sedgwick called the book "an important contribution", which offers a revealing insight into Italian esoteric milieu of the twentieth century.

Sedgwick has emphasized how an understanding of Reghini, Roman Traditionalism and this broader Italian esoteric milieu can be crucial for the study of the influential esotericist Julius Evola.

[8] His review especially found fault with the way Giudice handled source criticism, relying on political police records in portraying the relationship between Reghini and the Fascist regime.

He noted Giudice "may have misunderstood the function of the anonymous informant reports that make up the bulk of such dossiers; they are an inherently unreliable genre, continually concocting inaccurate allegations".
