C.S. Lewis belonged to the Oxford literary group known as The Inklings.
The Inklings were an informal discussion and writing circle associated with Oxford. Members read works in progress aloud, exchanged criticism, and discussed literature, mythology, and Christianity. J.R.R. Tolkien was among the most prominent members alongside Lewis, and Charles Williams also played an important role.
The group was not a formal university society with a fixed constitution. Its meetings took place in Oxford locations, including Lewis's rooms at Magdalen College and the Eagle and Child pub. The participants varied over time, and attendance was based more on friendship and literary connection than on an official membership list.
The name is sometimes mistaken for a publisher or academic department. It referred to a private circle of writers and scholars whose conversations influenced several major works of twentieth-century fantasy and Christian literature.
