BYELUY, ANDREI pen name of Boris Bugaiev, Russian writer, was born in Moscow, Oct. 7, 188o, the son of a well-known mathematician. When he graduated in 1904 from the Moscow university, he had already published poetry of a symbolic type. His books of poetry and rhythmic prose are symbolic phantasies, in essence spiritual, yet expressed in realistic images. The most famous of these are: Gold in Blue (1904), Ashes (1909) and The Urn (1909). His prose is best represented in three novels: The Silver Dove (1910), a psychological study of Russian religious sects, reminiscent of Gogol; Petersburg (1916), a gloomy, fantastic tale about Russian pre-revolutionary realities; Kotik Letaiev (1922), an imaginative autobiography—the prob lems of life and the mind, seen through the soul of a child. One of the most remarkable of his books is The Reminiscences of A. Blok.
