C.S. Lewis aficionados know his unfinished "Launcelot," collected in Narrative Poems; but fewer know that he wrote an Arthurian poem intended for his first book, Spirits in Bondage, which was rejected by his publisher. The manuscript has since been lost, but a few things can be known or reasonably conjectured about the poem. This paper will cover the following topics:

(1) Lewis's mention of the poem in his correspondence with Arthur Greeves,

(2) its title,

(3) its date of composition,

(4) its source (quoted),

(5) its probably application for Spirits in Bondage, and

(6) the loss of its manuscript
