The epilogue, Chapter 7, describes Guccia's death and the decay of the Circolo from the interwar period through the Second World War, when the bombing of Palermo in 1943 destroyed the Palazzo Guccia. Two mathematicians particularly assisted Guccia in improving his mathematical society and the I Rendiconti i : the French Poincaré and the well-known Italian mathematician Vito Volterra (1860-1940). The other important mathematician in Guccia's scientific life was Poincaré, who supported Guccia throughout his career by contributing important papers to the I Rendiconti i . However, the book remains captivating, sheds light on a still little-known story, and contains unpublished documents on the origins of the Guccia family, the role of Guccia's uncle Giulio Fabrizio Tomasi, and the first years of Guccia's life.
