He cooperated with the historian Joannes Lucius, translated classical authors, wrote a biography of the Dubrovnik writer Junije Palmotic and a poem about the earthquake in Dubrovnik. In the literary and scientific circle of pope Alexander VII and Queen Christina of Sweden Gradic discussed scientific and philosophical issues. Along with philosophy, he engaged in mathematics, physics, astronomy, literature and diplomacy.
Antonija Krasnik holds a distinct place of the first Croatian woman applied artist and designer in Croatian history. She participated at numerous exhibitions of decorative art in Vienna, Berlin, Munich, London, St. Louis, Torino and Paris and her works were published in the most prominent European journals for art and culture. In all works by Antonija Krasnik evident is superior delicacy in shaping decorative objects and objects of use, which is an authentic expression of the spirit of time and style at the turn of the century, but above all a peculiar expression of her aesthetic sensibility.
Ranko Marinkovic proved himself as key personality in Croatian literature in the second half of the 20th century. From his very beginnings in literature, accepted before the Second World War as the author of particular literary skill and sensibility, Ranko Marinkovic asserted himself in the second half of the 20th century as the key personality in Croatian literature, a writer of explicit critical vocation, interested in contemporary topics, but also a creator of strong intellectual reflection – ready for the challenges of radical modernism and open to probations of postmodern relativism. He tried almost all genres and proved his creativity as an exceptional story teller, novel writer, dramatist, critic and essayist.

In the history of world opera art, known as "legendary Ternina", she is still referenced in all encyclopedias.
