Abstract
Detailed monitoring of the life and influence of Prevost of Vyšehrad and Chancellor of King Přemysl II. It should lead to a finding that it was actualy this Peter, which was 1264 as the King's Enwoy at the Curia in Orvieto, who was present in the miracle in Bolsena.
Safe conclusion rests on the interpretation of some of the entries in one of the manuscripts of the form of Henry from Isernia.
