Huge attention has been given to their literary work for they are the best indicator how big the influence Jerome was on Marulić. Those literary creations were the biggest source for the continuing research. Next is literary work of Marko Marulić where the Jerome's influence is easily seen. The best indicator of Marulić's fascination with Saint Jerome is the work Repertorium in which Marulić wrote quotations and sayings which he found in Jerome's work. Those quotations Marulić used in writing his literary work and most of all in his famous De institutione bene vivendi per exempla sanctorum, using them in the same or similar form, but keeping the origin. In this paper are listed examples comparing Repertorium with De institutione bene vivendi per exempla sanctorum.

After an overview of literary creations Marulić wrote modeled from Saint Jerome, it is listed all the literary work Marulić wrote about Saint Jerome. It's biography Vita divi Hieronymi with controversal document In eos qui beatum Hieronymum Italum fuisse contendunt that tried to explain where comes such an interest for Jerome as a Saint, for fiercely defending his origin and proving that he was from Dalmatian coast.
