On a winter’s night in 1957 (or 1959)1 a guionista, or writer of comics, is working late in the atelier of his Buenos Aires home when a man dressed in futuristic clothing materializes in the chair across from him [Fig. 1]. The man tells the writer that he travels through time, searching the centuries for those he has lost. He has been called by hundreds of names, the most apt of which is el Eternauta [the Eternaut] because of his “triste y desolada condición de peregrino de los siglos” [sad and desolate condition as a time pilgrim] (EtI_OSL 5). He eventually reveals that his original name was Juan Salvo, but the identity of this ordinary man has been altered by extraordinary events. The account of these events that we are now reading, the guionista declares, is the tale of the Eternauta just as the time traveler told it to him that night.
