One of the most popular works by the Italian theologian Ambrogio Marliani (1562-1632) is the “Theatrum Politicum,” which details the rules of conduct, morals and values of a duke and other nobles. In an ornate, baroque title page, in order to highlight the most important details of the book: the title, author, place and year of publication, are presented in capital letters. The title is perceived as a mark that helps to identify and distinguish the publication. At the same time, in the early years of the early modern period, the purpose of the title page was to promote and sell the publication. The title pages of the books in the 16th-18th centuries did not contain a bibliographic data arranged one after the other but a cohesive and continual text, combining the necessary data into a grammatically correct sentence.
