"The Knight's Tomb" is a short poem of eleven lines written by Samuel Taylor Coleridge, and published by the author in 1834.

[4] Where is the grave of Sir Arthur O'Kellyn?Where may the grave of that good man be?—By the side of a spring, on the breast of Helvellyn, Under the twigs of a young birch tree!The oak that in summer was sweet to hear,And rustled its leaves in the fall of the year,And whistled and roared in the winter alone,Is gone,—and the birch in its stead is grown.—The Knight's bones are dust,And his good sword rust;—His soul is with the saints, I trust.James Gillman says that these lines were composed 'as an experiment for a metre', and repeated by the author to 'a mutual friend', who 'spoke of his visit to Highgate' and repeated them to Scott on the following day.

[5] They run thus:— The knights are dust,And their good swords are rust;—Their souls are with the saints, we trust.Gillman says that the Ivanhoe quotation convinced Coleridge that Scott was the author of the Waverley Novels.

By the marge of a brook, on the slope of Helvellyn,Under the boughs of a young birch-tree.The Oak that in summer was pleasant to hear,That rustled in autumn all wither'd and sear,That whistled and groan'd thro' the winter alone,He hath gone, and a birch in his place is grown.

The knight's bones are dust,  His good sword is rust;His spirit is with the saints, we trust.This version must have been transcribed from a manuscript in Lockhart's possession, and represents a first draft of the lines as published in 1834.
