“He told himself that he would have to start reading thicker books: they lasted longer, and made more comfortable pillows.” 

Throughout the novel, books hold symbolic meaning. They are treasure troves of knowledge and learning, containing ancient wisdom and informative stories. The Englishman, whom Santiago will meet later in the novel, carries with him a large library in his quest to become an alchemist. At the beginning of the novel, the importance of books to a lowly shepherd boy seems somewhat simpler. Before Santiago entertains dreams of traveling to another continent and seeking out his fortune, he is rambling through the wild plains of Andalusia. His use of books as a pillow carries metaphorical meaning: They comfort him and allow him to sleep easier. By reading thicker books, he will open himself up to a larger and more detailed world. His first wish—before he dreams of visiting pyramids or Fatima—is simply of owning a bigger book that will provide a better pillow and a better story. As his imagination and literacy grows, so does his comfort. The books are an escape, allowing him to travel to other worlds. The wish for a larger and more comfortable pillow is a foreshadowing of Santiago’s dreams of traveling far and wide.
