This is a presentation of general information on the prayer-book by Nikola Hermon "Sacred Flour"( ,, Brašno duhovno.), published in 1693. A more detailed analysis deals with his structural use of the standard language based on the chakavian dialect of Rijeka, with an interpellation of his norms. The possible connection with previous prayer-books is contemplated, especially with "Paradise of the Soul"(" Rajem duše") by Nikola Dešić, published in 1560 and. "The Spirit's Garden"("Dušnim vrtom") by Baltazar Milovac, published in 1664.
