In a couple of articles published at this time, the literary scholar described the phenomenon as a form of unmediated or improvisational speech.[5] He applied it specifically to Nikolai Gogol's short story The Overcoat, in a 1919 essay titled How Gogol's "Overcoat" Is Made.[2] Eikhenbaum saw skaz as central to Russian culture, and believed that a national literature could not develop without a strong attachment to oral traditions.[3] Among the literary critics who elaborated on this theory in the 1920s were Yury Tynyanov, Viktor Vinogradov, and Mikhail Bakhtin.[5] The latter insists on the importance of skaz in stylization[6], and distinguishes between skaz as a simple form of objectified discourse (as found in Turgenev or Leskov), and double-voiced skaz, where an author's parodistic intention is evident (as found in Gogol or Dostoevsky).[7]
