Symbolism In Franz Kafka's Metamorphosis

In Franz Kafka's short story Metamorphosis symbolism plays a great part in developing Gregor's character and life. First, s picture Gregor has of a woman is the representation of his last strand of human life in addition to the furniture in his bedroom. Secondly, the apple that Gregor's father implants into his back is a representation of good and evil within the Samsa family. Lastly, Gregor's door represents his isolation from humanity and his true transition into a bug.
To begin, although Gregor has very few human like aspects before becoming a bug. He kept a "huge picture he cut out... it showed a lady fitted out with a fur hat and fur boa... towards the viewer" (1 and 2) throughout Gregors transition this picture remains to be his one
Yet, as time passed "The rotten apple in his back and the inflamed surrounding area." (89) Gregor began to realize that he was no longer part of this family and as the apple in his back so did the to be rotten so did the relationship he began to have.
Lastly, Gregor's shut door is also a symbol. When the story began Gregors door was kept shut and locked by will. When he became a bug he thinks "Now, quite apart from the fact that the doors were locked should he really call out for help?" (12) Gregor kept his family out by shutting his door and keeping it locked this was his way of self isolation. Yet, as Gregor transforms into a bug he soon feels the door as developing a sense of loneliness and isolation from his family rather than self inflicted.
In conclusion, Kafka used many symbols to help develop is story such as the woman in the picture who provided Gregor with a sense of humanity and the furniture which was stripped from him and denying him his human aspects. Also, the apple which brought Gregor closer to his family but as it rotted so did their relationship. Finally, his door is Gregors way of isolating himself from his family in the beginning but soon becomes the Samsa's way of keeping what they used to know as Gregor
