Why did Alice Longfellow have a brass seal shaped like a fasces? We do not know the answer for sure, but one possibility is that it had to do with her admiration for the fascists who assumed power in Italy in the 1920s.
Alice traveled to Italy repeatedly, first as part of her family's Grand Tour in 1868-1869 then again in 1913, 1922 and 1927. She had a great love of Italian culture, and was distressed to see the unrest and general chaos the country was thrown into after the end of World War I. She was in Italy in 1922 when Benito Mussolini and the fascists marched on Rome and assumed control of the government. She recorded her experiences of this 1922 trip in an essay title "The Fascisti as I Saw Them." In her essay she gave an extremely positive view of the Italian fascists, saying "The Fascist government is clearly favorable to every solution which favors individual initiative, and the free development of the energies of labor in the economic field." On a subsequent trip in 1927 she was received by Mussolini, and presented him with a copy of her father's translation of Dante's Divine Comedy.
The seal is not listed among the items in Alice's Study in a 1912 inventory, but does occur in a later survey done in 1954, indicating that Alice acquired it between 1912 and her death in 1928. Exactly why and when she acquired it may never be known for sure, but the prospect of a connection between the seal and Alice's views on the Italian fascists seems promising.
