What was the pen name C.S. Lewis used for The Pilgrim’s Regress?

C.S. Lewis used the pen name Clive Hamilton for The Pilgrim’s Regress.

The Pilgrim’s Regress was published in 1933 and was Lewis’s first published work of prose fiction. Its subtitle, An Allegorical Apology for Christianity, Reason and Romanticism, signals its intellectual and religious concerns.

Lewis chose “Clive Hamilton” before becoming widely known as a Christian author. Later editions identified him as C.S. Lewis, making the pseudonym mainly a historical detail for readers studying his early career.

The book is an allegorical journey influenced by John Bunyan’s The Pilgrim’s Progress. Its protagonist, John, travels through a landscape representing philosophical, cultural, and religious ideas rather than a literal geography.
