Metamorphosis is a book by Franz Kafka, first published in 1915. It has been cited as one of the seminal works of fiction of the 20th century and is studied in colleges and universities across the Western world. The story begins with a traveling salesman, Gregor Samsa, waking to find himself transformed (metamorphosed) into a large, monstrous insect-like creature. The cause of Samsa's transformation is never revealed, and Kafka himself never gave an explanation. The rest of Kafka's novella deals with Gregor's attempts to adjust to his new condition as he deals with being burdensome to his parents and sister, who are repulsed by the horrible, verminous creature Gregor has become. Kafka was born into a middle-class, German-speaking Jewish family in Prague, the capital of the Kingdom of Bohemia, then part of the Austro-Hungarian Empire. In his lifetime, most of the population of Prague spoke Czech, and the division between Czech- and German-speaking people was a tangible reality, as both groups were strengthening their national identity. The Jewish community often found itself in between the two sentiments, naturally raising questions about a place to which one belongs. Kafka himself was fluent in both languages, considering German his mother tongue.
