Maxim Gorky's novel "Mother" is usually considered to have been the first socialist-realist novel. Gorky was also a major factor in the school's rapid rise, and his pamphlet, "On Socialist Realism", essentially lays out the needs of Soviet art. Other important works of literature include Fyodor Gladkov's "Cement" (1925), Nikolai Ostrovsky's "How the Steel Was Tempered" and Mikhail Sholokhov's two volume epic, "Quiet Flows the Don" (1934) and "The Don Flows Home to the Sea" (1940). Yury Krymov's novel "Tanker "Derbent"" (1938) portrays Soviet merchant seafarers being transformed by the Stakhanovite movement.
