What was the title of C.S. Lewis’s 1933 allegorical book about a man’s spiritual journey?

The Pilgrim’s Regress was C.S. Lewis’s 1933 allegorical book about a man’s spiritual journey.

The book follows John, who leaves his home after receiving a vision of a distant island. His journey through a landscape filled with symbolic characters and locations reflects Lewis’s intellectual and spiritual development. The subtitle identifies it as an allegorical apology for Christianity, reason, and romanticism.

The work was Lewis’s first published book. It appeared after his conversion to Christianity and before the popular apologetic writings that made him widely known. Lewis later added a preface explaining the book’s symbolism and acknowledging that some readers might find its references difficult.

The title echoes John Bunyan’s The Pilgrim’s Progress, but Lewis’s book is not a retelling of Bunyan’s narrative. Its modern philosophical and autobiographical elements make it a distinct work.
