What was the pen name C.S. Lewis used for poetry published in the 1920s?

C.S. Lewis used the pen name Clive Hamilton for poetry published in the 1920s.

Lewis published his first two poetry collections under different pseudonyms. Spirits in Bondage appeared in 1919 under the name Clive Hamilton, while Dymer was published in 1926 under the same name. “Clive” came from his childhood nickname, while Hamilton was connected with his family background.

The pseudonym can be confused with Lewis’s later use of “N.W. Clerk,” the name attached to his 1955 autobiography, Surprised by Joy. It is also distinct from his public author name, C.S. Lewis, formed from his given names Clive Staples. His early poetry is less widely read than his Christian apologetics and fiction, but it shows the literary interests he developed before becoming famous for Narnia.
