Podrobna istraživanja o Petrićevu grobu, provedena u crkvi Sv. Onofrija u Rimu, u Muzeju Torquata Tassa u Rimu i u literaturi o Tassu urodila su spoznajom o karakteru odnosa između Franje Petrića i kardinala Cinzija Aldobrandinija za vrijeme Petrićeva rimskog razdoblja: Petrić je bio službeni dvorski filozof kardinala Aldobrandinija, državnog tajnika Papinske države i nećaka pape Klementa VIII. Kardinal Aldobrandini, tijesno povezan s Torquatom Tassom, najvjerojatnije je odlučio da Petrić bude ukopan u Tassov grob u crkvi sv. Onofrija u Rimu, (...) da mu dvorski pjesnik i filozof počivaju zajedno.Thorough research on finding Petrić’s grave, conducted in the Church of St. Onophrio and the Torquato Tasso Museum in Rome, as well as in literature, has resulted in the knowledge about the nature of relationship between Franjo Petrić and Cardinal Cinzio Aldobrandini during Petrić’s Roman period: Petrić was the official court philosopher of Cardinal Aldobrandini, the secretary of State of His Holiness the Pope, and the nephew of Pope Clement VIII. Cardinal Aldobrandini, closely connected with Torquato Tasso, most likely chose Tasso’s grave in the Church of St. Onophrio in Rome as the place of Petrić’s burial, in order that his court poet and philosopher rest together.
