The following is a direct quote from Piers Armstrong’s Third World Literary Fortunes. I encourage students at all levels to consider closely the research that has already been completed, and, especially, that research which has yet to be taken up.
The information was compiled by Piers Armstrong from the computerized databases of M.L.A. (Modern Language Association) and D.A.I. (Dissertations Abstract International):
“In the case of Guimarães Rosa, literary-centric issues predominate (35 of 57 items). His work is fertile ground for the application of theory (“kenosis”; Bakhtin; “reader-response” theory…). The author is compared to a rich array of eminent world writers (Conrad, Mann, Melville, E. Bronte, Calvino, Rulfo, Tolstoy, Céline, Hesse, Faulkner, García Márquez, Borges, Cortázar, Frisch…). Most significantly, Guimarães Rosa is featured in no less than three studies attempting a definition or characterization of the New Novel of Latin America (under various titles). Four studies focus on meta-literary issues. The writer is also recognized as a significant voice on a broad range (15 studies) of metaphysical issues (time, the devil , magic, madness, mystery and antithesis, deferral/plurality, self-representation, Taoism, the baroque, predestination and freewill, desire, redemption, and occidental-oriental universalism). The other main area of consideration is the depiction of nature in his work (5). Interestingly, regionalism is barely pursued. Questions of ethnicity, Brazilian identity, sociohistoric testimony and politics are virtually absent.”
