The author explores different paths of literary creation: poetry, essay, translation, and university teaching. If his poetry appears in the best pages of Latin American literature, then his translations and essays, which include from Greco-Latin to pre-Columbian Mexican iconography, are elegance, rigor, and perfection models. They evoke univers of words, forms, and structures that together give life to one of most diverse and prolific works of literature in Spanish.
