The work is actually a brochure numbering only 32 pages. It was intended as a draft for a much larger work, which the author never managed to realize. It begins with a dedication to
Emperor Leopold, naming him, among others, "king of all Croatia", as a reflection of political ambitions outlined in this book. This is followed by an introductory in verse
Monitio ad Prodromum, where goals and ideas of the work are laid out. In the same poem consisting of 9 couplets, he encourages the reader to send him more material such as sources and coats of arms. The whole introductory part is meticulously structured, thoroughly stylized (demonstrating Vitezović abilities as a printer), and ornamented with rhetorical devices such as puns,
litotes,
homeoteleuton, etc. In
Croatia Rediviva, Vitezović sets out to first establish the origin of the
Croat name (
ethnogenesis), and then the extent of boundaries of Croatia, trying to reconcile contradictions in various sources ranging from chronicles such as
Chronicle of the Priest of Duklja to historians
Mavro Orbini and
Johannes Lucius. Using
White Croatia,
White Croats and the legend of
Lech, Czech and Rus as basis, Vitezović declared all
Western and
Eastern Slavs as Croats. The second part is a polemic against those who view Croats as different to
Slavs and
Illyrians. He maintains Slavs and Croats are synonyms, holding the term "Illyrian" as merely a
Greek and
Latin name for Slavs. By denouncing Lucius as a
Venetian apologist, he negates Venetian claim to
Dalmatia. Finishing the book with the newly attained belief that all Slavs held the Croat name, he views all the Slavic lands as being divided in two main parts: Northern Croatia (
Croatia Septemtrionalis, which included
Hungary) and Southern Croatia (
Croatia Meridionalis), the latter being further divided into
Red Croatia and White Croatia. White Croatia he divided in four regions: • Maritime Croatia •
Mediterranean Croatia • Mesopotamian Croatia •
Alpine Croatia These newly coined terms corresponded to actual region of Dalmatia,
Slavonia,
Noricum, whereas Red Croatia consisted of
Serbia,
Macedonia,
Bulgaria and
Odryssia. ==Interpretations and influence==
