The philosophy of Heraclitus as thematic subtext of Julio Cortázar's 'All Fires the Fire' In an interview he gave a few months before his demise, Julio Cortázar identified two teachers from the Escuela Normal ‗Mariano Acosta' in Buenos Aires as defining influences on his intellectual career. Don Arturo Marasso, his professor of Greek and Spanish literature, was soon aware of Cortázar's literary vocation. He initiated the young Cortázar in ancient mythology, invited him to his home and gave the talented but poor student free access to his personal library. Marasso introduced him to Sophocles, taught him how to read Homer well, and made him appreciate the lyric poetry of Pindar. Under Marasso's influence he also read all the Platonic dialogues. His philosophy teacher, Vicente Fatone, a specialist of logic and epistemology, broadened his knowledge of ancient philosophy and made him read Aristotle. Cortázar recalls that the challenging Fatone inspired him to consider a career in philosophy. Although he did not have the temperament for systematic philosophy, he recalls: ‗Me fascinaba porque la filosofía te mete en lo fantástico, en lo metafísico, pero no tenía un temperamento para avanzar o sistematizar en el campo filosófico y la abandoné.' (Soriano 1983: 4) Heraclitus in the works of Cortázar Throughout his life and writings, Cortázar remained fascinated by classical culture. 1 He seems to have been particularly interested in a philosophical author whose fragments have been compared to the choral works of Pindar and who has been called ‗one of the most powerful 1 Two forthcoming articles by Aagje Monballieu study the importance of the classical tradition for Cortázar: ‗La vocación helenística de Julio Cortázar.

Cortázar owned several scholarly books on the philosophy of Heraclitus and it is even fair to say that he collected editions and translations of the Heraclitean fragments. His collection included editions of the original Greek next to Spanish, French and English translations by Battistini, Brun, Farré and others. His love for Heraclitus was also known to his friends: we know e.g. that his copy of Heraclitus by Philip Wheelwright (1959) was a gift from his friend the critic Ana María Hernández. 2 Heraclitus appears quite often in his writings: both in early and in very late publications. In a short essay published a few years before his death, ‗Un sueño realizado' (1980), 3 Cortázar mentions Le rayon vert by Jules Verne (1882) and he compares this natural phenomenon to the transformation of the elements as described by Heraclitus. 4 ‗Sobremesa' (Final del juego), published in 1964, has fragment DK 52 as its motto: ‗...
