The introduction of Steinbeck's Pearl is representational of the author's personal struggle against the deceitfulness of power, wealth and fame. The "pearl" reaches an almost mythological status representing dreams and ambitions. The text also confronts controversial philosophies such as simony and the rejection of diverse social and multicultural relations. The biographical parallel can be found in the first three pages of the introduction. Hence, the introduction is the context by which we understand the text as an allegory similar to John Bunyan's Pilgrim's Progress.
The introduction to The Pearl not only serves to set up the plot, but also lets the reader know that the story is a moral lesson, a "parable," based upon a folk tale. The repetition of 'they tell' and the use of 'they say' adds to the element of the oral tradition that lies within the heart of folk tales. It introduces the three main characters in the novel, Kino, Juana, and the ill-fated child, Coyotito. The reader also is warned that this will be a tale of both 'good' and 'bad' ; most folk tales and all parables teach a lesson. Thus, this introduction also serves to let the reader know that a lesson will be learned by the end of this novel.
