The baptismal font with the name of duke Višeslav, discovered in the Capucin monastery in Venice during the 19th century, is still of great interest to a number of scholars. The reason for that are the names of priest John, who donated the monument and duke Višeslav, whose name was used as a time reference in the inscription. The attempt of identification of duke Višeslav was one of the first problems that scholars faced and was one of the causes which led to the wrong interpretations related to the origin as well as dating. Throughout researching the literature that deals with this topic a better insight in different approaches has been achieved. Some of the approaches led to the important findings, while other led to completely wrong conclusions. Question related to the origin of this monument prompted many discussions due to the fact that some of the scholars have considered the town of Nin to be the right answer, while others have put more emphasis on the Venetian origin to be more accurate one. However, the theory of Venetian origin entails revaluating the facts about Croatian history and cultural heritage. This is the reason why it is not surprising that the interest in this topic is still present among scholars.
