In this capacity, he formulated the last will and testament of one Kaba in favor of the Pannonhalma Abbey upon the order of King Béla III, who issued the charter on a Sunday, while sitting under an oak tree at the palace of comes Scene in Esztergom.
[3] He formulated that famous document in that year, in which Béla III emphasized the importance of written records, ordering that a charter was to be issued for all transactions proceeding in his presence.
Historian Attila Zsoldos analyzed the document in detail and revealed the contradictions between archontological data, which still exist despite that historiographical efforts which tried to correct the charter's date to 1183 or 1185.
As Peter's namesake successor in the Archdiocese of Split already appears in 1191, it implies that he was transferred to the Archbishopric of Kalocsa prior to that, presumably in 1190, which suggests that Paul died in that year.
Other scholars rejected this theory because Paul's death occurred still during the reign of Béla III and the chronicler referred to the monarch as a deceased person.
