Acquainted with Grief, Gadda's first novel, set in an imaginary South American country, appeared in 1938. His masterpiece, That Awful Mess on the Via Merulana, was serialized after the war, but only published as a book in 1957. Both novels, like much else that Gadda wrote, were left incomplete. Among Gadda's other notable works are essays, film and radio scripts, a travel book, and his journals from World War I.
