# Barnabas — The Castle character guide > Barnabas in The Castle by Franz Kafka. **Role:** supporting **Also known as:** Barnabas, the Barnabas **First appearance:** 0003-ii ## Snapshot A young would-be Castle messenger who carries K.'s hopes up the hill and returns with nothing but the ache of never being issued an official suit. ## Who they are Barnabas is K.'s one living thread to the Castle, a messenger whose sincerity is matched only by the uncertainty of whether he is truly employed at all. His family's disgrace and his own unconfirmed status make every errand a gamble, and his sister Olga's long explanations reveal how thin the line is between service and exclusion. He matters because he embodies the book's central question: whether the Castle's silence is judgment, bureaucracy, or simply nothing. ## Relationships ### [Olga](https://www.betterreads.dev/discover/the_castle_se/characters/olga) _family_ Barnabas and Olga are brother and sister, with Olga fiercely protective and supportive of Barnabas in his difficult role as messenger. ### [K.](https://www.betterreads.dev/discover/the_castle_se/characters/k) _professional_ Barnabas serves as K.'s unreliable messenger to Klamm, creating a tense and uncertain professional bond. ### [Amalia](https://www.betterreads.dev/discover/the_castle_se/characters/amalia) _family_ Amalia is Barnabas's sister, and their relationship is strained by the family's disgrace following Amalia's rejection of Sortini. ### [Klamm](https://www.betterreads.dev/discover/the_castle_se/characters/klamm) _professional_ Barnabas works as a messenger for Klamm, but his status and the effectiveness of his service are constantly in doubt. ### [Olga](https://www.betterreads.dev/discover/the_castle_se/characters/olga) _family_ Barnabas and Olga are brother and sister, with Olga fiercely protective and supportive of Barnabas in his difficult role as messenger. ### [K.](https://www.betterreads.dev/discover/the_castle_se/characters/k) _professional_ Barnabas serves as K.'s unreliable messenger to Klamm, creating a tense and uncertain professional bond. ### [Amalia](https://www.betterreads.dev/discover/the_castle_se/characters/amalia) _family_ Amalia is Barnabas's sister, and their relationship is strained by the family's disgrace following Amalia's rejection of Sortini. ### [Klamm](https://www.betterreads.dev/discover/the_castle_se/characters/klamm) _professional_ Barnabas works as a messenger for Klamm, but his status and the effectiveness of his service are constantly in doubt. ### [Olga](https://www.betterreads.dev/discover/the_castle_se/characters/olga) _family_ Barnabas and Olga are brother and sister, with Olga fiercely protective and supportive of Barnabas in his difficult role as messenger. ### [K.](https://www.betterreads.dev/discover/the_castle_se/characters/k) _professional_ Barnabas serves as K.'s unreliable messenger to Klamm, creating a tense and uncertain professional bond. ### [Amalia](https://www.betterreads.dev/discover/the_castle_se/characters/amalia) _family_ Amalia is Barnabas's sister, and their relationship is strained by the family's disgrace following Amalia's rejection of Sortini. ### [Klamm](https://www.betterreads.dev/discover/the_castle_se/characters/klamm) _professional_ Barnabas works as a messenger for Klamm, but his status and the effectiveness of his service are constantly in doubt. ## In the story ### [II](https://www.betterreads.dev/discover/the_castle_se/chapters/ii) Delivers the letter from the Castle; leads K. to his family home instead of the Castle; reveals his ordinary background and coarse clothing; is revealed to be a mere messenger, not a Castle insider. ### [Chapter X](https://www.betterreads.dev/discover/the_castle_se/chapters/x) Delivers a letter from Klamm to K. and receives a new message to take to the Castle; K. questions his reliability as a messenger. ### [XI](https://www.betterreads.dev/discover/the_castle_se/chapters/xi) Referenced in K.'s thoughts as the messenger to Klamm. ### [XIV](https://www.betterreads.dev/discover/the_castle_se/chapters/xiv) Not yet returned from the Castle; K. relies on him for messages. ### [XV](https://www.betterreads.dev/discover/the_castle_se/chapters/xv) Barnabas is discussed extensively as the messenger struggling with doubt, anxiety, and the ambiguous nature of his service to the Castle. ### [Amalia's Punishment](https://www.betterreads.dev/discover/the_castle_se/chapters/amalia-s-punishment) Mentioned as having been ignorant of the affair and seeking explanations. ### [Petitions](https://www.betterreads.dev/discover/the_castle_se/chapters/petitions) Works as an assistant for Brunswick to support the family. ### [Olga's Plans](https://www.betterreads.dev/discover/the_castle_se/chapters/olga-s-plans) Olga's brother, who became a Castle messenger after two years of waiting; his initial arrogance faded into hopelessness, but he was revived by the task of delivering letters to K. ### [XVI](https://www.betterreads.dev/discover/the_castle_se/chapters/xvi) Barnabas delivers the message that Erlanger wants to see K. at the Herrenhof. ### [Additional Note](https://www.betterreads.dev/discover/the_castle_se/chapters/additional-note) Mentioned in relation to Olga's comment about the endless reflections his letters give rise to, illustrating the novel's theme of endless interpretation. ## Links - HTML: https://www.betterreads.dev/discover/the_castle_se/characters/barnabas - Book: https://www.betterreads.dev/discover/the_castle_se - All characters: https://www.betterreads.dev/discover/the_castle_se/characters
