Under what pseudonym did C.S. Lewis publish his early poetry?

C.S. Lewis published his early poetry under the pseudonym Clive Hamilton.

Lewis used the name Clive Hamilton for Spirits in Bondage, published in 1919, and Dymer, published in 1926. The pseudonym combined his first name, Clive, with Hamilton, a family name connected to his mother’s side. He was not yet the celebrated Christian writer associated with the initials C.S. Lewis.

The books appeared before his conversion to Christianity and before the publication of his best-known apologetic and fictional works. Using a pseudonym allowed Lewis to present the poems separately from his personal identity and academic career.

The name should not be confused with Lewis’s later use of the initials C.S. Lewis or with fictional and literary figures who influenced him. Clive Hamilton was specifically the name attached to these early poetic publications.
