Lazarillo de Tormes, published simultaneously in Alcalá de Henares, Burgos and Antwerp in 1554, is generally considered the first picaresque novel. The Wikipedia article about the picaresque novel contains a section about its sources, which says,
The curious presence of Russian loanwords in the text of the Lazarillo also suggests the influence of medieval Slavic tales of tricksters, thieves, itinerant prostitutes, and brigands, who were common figures in the impoverished areas bordering on Germany to the west.
The section about the genre's history also says,
The Twelve Chairs (1928) and its sequel, The Little Golden Calf (1931), by Ilya Ilf and Yevgeni Petrov became classics of 20th-century Russian satire and the basis for numerous film adaptations.
Are these then the first Russian picaresque novels? Or are there earlier ones, inspired by stories about Slavic tales of tricksters, as mentioned in the first quote?
