 Changing the name of the abbot of the first part from " Father Juan " to " Abbot Arkos " strengthened the cyclical / recurrence motif , since the name of the first abbot encountered , " Arkos " , begins with the first letter of the Latin alphabet and the name of the last abbot , " Zerchi " , begins with the last letter . Miller also expanded scenes , increasing their importance : for instance , the initial encounter between Brother Francis and Abbot Arkos in " Fiat Homo " grew from two pages in the short story to eight pages in the novel . Abbot Arkos was shown to possess doubts and uncertainty , unlike the dogmatism of Father Juan .
