This is one of the best of the numerous recent studies of the Roman Question. The author, the well-known political writer of the Echo de Paris, places the Lateran Treaties in their proper historical setting, showing them as a logical development in Vatican foreign policy during the last hundred years. Chapters are also set aside for a discussion of the personality and policy of the Pope, Cardinal Gasparri and Premier Mussolini. A final chapter reviews the relations of France with the Vatican and criticizes the French Government's "abdication" of influence. The work is fully documented throughout and shows both care and imagination. An appendix gives the text of the recent accords, as well as extracts from some of the earlier documents defining the temporal power of the Pope.
