The collection Croatian Tales of Long Ago is considered to be a masterpiece and features a series of newly written fairy tales heavily inspired by motifs taken from ancient Slavic mythology of pre-Christian Croatia. Croatian Tales of Long Ago are seen as one of the most typical examples of the writing style of Ivana Brlić-Mažuranić. The book has been compared by literary critics to Hans Christian Andersen and J. R. R. Tolkien due to the way it combines original fantasy plots with folk mythology.
