A significant number of church codices from this time have survived. In Zagreb there is a Liber psalmorum which was illuminated in Benedictine style by prior Majon for archbishop Paul of Split (c. 1015–1030). In Vatican there is a Breviary, also in monte-cassino Benedictine style (initials of intertwined leaves, interlace and animal heads) which originates from monastery of St. Nicola in Osor. The same style of illumination we can found in Breviars in Trogir, Šibenik and Dubrovnik but there are many that were recorded (like 47 books in only one church in monastery of St. Peter in Seka) but not preserved.
