In 1990 Oliveira directed "No, or the Vain Glory of Command" ("Non, ou a Vã Glória de Mandar"), starring Cintra, Dória and Silveira. The film depicts the military history of Portugal, focusing on its defeats over its victories. The film's historical action includes the assassination of Viriathus, the Battle of Toro, the Battle of Alcácer Quibir and the Portuguese Colonial War. The only exception to the historical scenes is a sequence depicting the mythical Isle of Love, which celebrates Portuguese explorers and discoverers, instead of its military figures. The Isle of Love features winged cupids, beautiful nymphs and the goddess Venus. The film competed at the 1990 Cannes Film Festival. In 1991, Oliveira directed "The Divine Comedy" ("A Divina Comédia"). Set in a mental institution, the film is not an adaptation of Dante Alighieri's famous work but derived from stories on the Bible, José Régio's play "A Salvação do Mundo", Fyodor Dostoyevsky's "Crime and Punishment" and "The Brothers Karamazov", and Friedrich Nietzsche's "Antichrist". Oliveira stated that all of the texts he uses "deal in some way with the problem of sin and the possibility of redemption, and in this sense they all derive ultimately from the same source." The film stars Maria de Medeiros, Miguel Guilherme, Luís Miguel Cintra, Leonor Silveira and Diogo Dória and competed at the 1991 Venice Film Festival, where it won the Grand Special Jury Prize award.
