In the summer of 1096, Pegau Abbey not far from Leipzig was consecrated. The founder of the monastery Wiprecht of Groitzsch and his wife the Přemyslid Judita, daughter of King of Bohemia Vratislaus II (1061-1092) were not absent from the spectacular celebration. According to the Annals of Pegau, Judita approached then with a golden crown on her head and wearing a dress with golden thread with a cloak to the local altar on which she placed the items decorated with gold and precious stones and dedicated them to the monastery. The study sets the question of to what extent this report is trustworthy, whether these objects were royal insignia and whether the act itself belongs to the ritual of ´sacrificing crowns´. Regarding the sovereign acts of this type, the study attempts to map the various symbolic levels of these acts, which the literature does not reflect in its entirety. The work predominantly offers an answer concerning the character and origin of the donated gems and paces it in the practice then of using specific royal diadems. and Lukáš Reitinger.
