Three sources have been preserved presenting the position taken by the Holy See regarding the holiness of Hedwig of Silesia. All of them were created on the day of canonization or shortly before. The basis for these texts were materials sent by the Polish side. To some extent, it is possible to determine what was in these materials. The aim of this paper is to answer the question whether and to what extent the Silesian hagiographer, when he wrote Vita maior of St. Hedwig around 1300, took into account the views of the papal curia. While it can be assumed that the canonization bull of the Duchess of Silesia was known to him, while it is possible that the author of the Life of Anna knew it, it is unlikely in relation to the authors of the Life of St. Salome and the Life of St. Kunegunde. The analysis of these last three works will focus on confronting the papacy's views on holiness with the opinions of relevant hagiographers.
