José Carlos Mariátegui devoted the most productive years of his short life (1894–1930) to analyzing contemporary Peru. Because of this emphasis, a substantial portion of the research conducted in the past thirty years has addressed his political and social thought. More recent investigations, however, have sought to document the significance of his aesthetic ideas, an appropriate development in light of Mariátegui's extensive writings on literature and the visual arts. For example, the periodical Amauta, which appeared under his editorship twenty-nine times between September 1926 and March 1930, was primarily a magazine of the arts and intellectual life, notwithstanding its political agenda and indigenista orientation. Also, Mariátegui's detailed essay on Peruvian literature, “El proceso de la literatura,” is the most extensive of the Siete ensayos de interpretación de la realidad peruana (1928). In addition, between 1924 and 1930, the widely read Lima weeklies Variedades and Mundial regularly published his critical articles on national and international topics, including a large number of pieces on literature and the arts. Recent inquiries into Mariátegui's literary thought have addressed such issues as his modern concept of literary realism, the relationship between his artistic concerns and a Marxism that has been repeatedly characterized as “open,” and the role of aesthetic issues in his social agenda for Peru. This research has established Mariátegui's importance in the arts, not as a creative writer (although he did write poetry, plays, and short stories in his youth) but as one of Latin America's first practicing literary critics.
