El misterio de las puertas y las puertas del misterio en Kafka

The striking recurrence of the door image in Kafka’s works was highlighted in an article published in Buenos Aires in 1944 by Carlos Sandelín. This text was plagiarized years later by the Salvadorean writer Mario Hernández Aguirre. The present essay proves this misappropriation, analyses the characteristics and relevance of Sandelín’s thesis and concludes with a contribution of its own: the recognition of the concept of threshold as the center of Kafkaesque aesthetics.
