Benediktinci i benediktinke u Biogradu u ranom srednjem vijeku - Galović, Tomislav (Array, 2014)
The reign of king Petar Krešimir IV was a time of blossom for the city of Biograd. This is primarily demonstrated by the fact that king himself was behind the foundation of two Benedictine monasteries in the city. Further, first records of the Bishopric of Biograd and a name of a bishop of Biograd are to be found precisely in his charters. Hence the king is believed to have suggested in the middle of the 11th century the foundation of the bishopric. The male Benedictine monastery of St. John the Evangelist was formally established, as stated by the abbey's foundation charter, in February 1060. In this important document the convent is called royal: monasterium regale. For the deed of donation bestowed presumably between 1060 and 1062 by king Petar upon the female Benedictine monastery of St. Thomas in Biograd we have neither the original or the template, but only the donation's text that has been preserved in Libellus Policorion. With this deed the king remits all fiscal duties to the monastery and gives it a plot of land called Rasohatica by Tinj. Therefore it has been logically concluded that the king himself must have been the founder of the convent.
