Widerspruch zu Spanien and dem Kaiser (Stuttgart, 1879). This last work was translated into Italian by the author himself (Rome, 1879). Gregorovius was also something of a poet; he wrote a drama, Der Tod des Tiberius (1851), and some Gedichte (Leipzig, 1891).
His Romische Tagebiicher were edited by F. Althaus (Stuttgart, 1892), and were translated into English as the Roman Journals of F. Gregorovius, by A. Hamilton (1907).
