U radu se donosi prikaz arhivskog gradiva iz mletačke knjižnice Muzeja Correr, iz fonda Cicogna, u kojemu su sadržani prijepisi raznih pisama i ostale arhivske dokumentacije povezane s djelovanjem zadarskog nadbiskupa Vicka Zmajevića (1713. – 1745.). Osobita pozornost posvetit će se dosad neobjavljenom govoru nadbiskupa Zmajevića pred mletačkim Senatom prigodom preuzimanja službe zadarskog nadbiskupa i njegovu pismu papi o namjeri osnivanja glagoljaškog sjemeništa u Zadru. Analizirat će se njihov sadržaj te komparativnom metodom s dosad objavljenim rezultatima istraživanja u znanstvenoj literaturi i arhivskim podatcima pohranjenima u arhivu kongregacije De Propaganda Fide nastojati razmotriti diplomatske interakcije nadbiskupa Zmajevića prema mletačkoj vladi i crkvenoj hijerarhiji na početku njegova djelovanja u Zadru. In the fond Cicogna in the library of the Venetian Correr Museum (Museo Correr) there is a codex that contains transcriptions of various correspondence and archival documentation related to Vicko Zmajević who was Archbishop of Zadar between 1713 and 1745. Among these documents, one can find the transcription of Zmajević’s speech, which he held before the Venetian Senate on the occasion of his installation in the archbishopric office. Moreover, in this codex, there is also the transcription of his plea to Pope Benedictus XIII (1724 – 1730) regarding the foundation of the Glagolitic seminary in Zadar. The author particularly investigates the abovementioned two transcriptions and then correlates the content of these documents with the prior knowledge and research that was based mostly on the relevant literature and archival data kept in the Archives of the congregation De Propaganda Fide in Rome (Italy). The emphasis has been put on diplomatic interactions between archbishop Zmajević, Venetian authorities, and higher ecclesiastical institutions in the eighteenth century. On the basis of the investigated material author suggests a thesis that Zmajević’s diplomatic abilities largely influenced ecclesiastical and social life in Venetian Dalmatia and Albania in the eighteenth century. Moreover, the author maintains that in the context of the general history of the Catholic Church in Dalmatia and Albania archbishop Zmajević was an unavoidable historical character since without knowledge about his activities, many ecclesiastical, social, and political processes from this period cannot be properly explained and understood.
