Under what pen name did C.S. Lewis publish his first book of poetry in 1919?

C.S. Lewis published his first book of poetry, Spirits in Bondage, in 1919 under the pen name Clive Hamilton.

The collection appeared while Lewis was still a young man and was published before his career as a major Christian writer or fantasy novelist. Its poems reflect themes of suffering, confinement, war, and doubt. The choice of pseudonym allowed Lewis to present the work separately from his established personal identity.

“Clive Hamilton” was not Lewis’s birth name. His legal name was Clive Staples Lewis, and “Jack” was the name used by friends and family. Lewis later published poetry under his own name, including Dymer in 1926, which used the name Lewis rather than Clive Hamilton.

Readers sometimes confuse the pseudonym with the poet’s full name or with the title of Lewis’s later poem. Spirits in Bondage is the 1919 collection; Clive Hamilton is the literary name attached to it.
