''One morning, as Gregor Samsa was waking up from anxious dreams, he discovered that in bed he had been changed into a monstrous verminous bug.'' <br><br> With this startling, bizarre, yet surprisingly funny first sentence, Kafka begins his masterpiece, <i>The Metamorphosis</i>. It is the story of a young traveling salesman who, transformed overnight into a giant, beetle-like insect, becomes an object of disgrace to his family, an outsider in his own home, a quintessentially alienated man. Rather than being surprised at the transformation, the members of his family despise it as an impending burden upon themselves.<br><br> A harrowing--though absurdly comic--meditation on human feelings of inadequacy, guilt, and isolation, <i>The Metamorphosis</i> has taken its place as one of the most widely read and influential works of twentieth-century fiction. As W. H. Auden wrote, ''Kafka is important to us because his predicament is the predicament of modern man.''
