The study is dedicated to development of the Olomouc bishop’s seals in period between 1351 and 1457 with emphasis on their iconography. From the artistic point of view the analysed seals from above stated period represent the highest quality. In the same period we can notice significant transformation of typology of used matrixes. The study shows that those changes in some cases reflect the period mentality. The authors of the article also mention reasons that could motivate the individual bishops to choose the particular iconographic type. In that sense the authors further on analyse the basic iconographic motifs. The catalogue of the Episcopal seals represents the core of the study as well as the description of the official Coat of arms evolution till the end of the 15th century.
