This volume gathers Ricardo Piglia’s monumental project: the three volumes of The Diaries of Emilio Renzi. Emilio Renzi -writer and recurring alter ego in Piglia’s fiction- emerges from a mirror game rooted in the author’s full name: Ricardo Emilio Piglia Renzi. Acclaimed by critics and readers alike, these diaries span more than half a century (1957–2015), enriched with related texts and reflections. With obsessive precision and literary passion, Piglia documents a life shaped by writing, reading, and the mechanics of fiction. A cornerstone of Latin American literature, The Diaries of Emilio Renzi is now recognized as a modern classic of the autobiographical genre.
