Other admirers included Jane Austen, Alfred, Lord Tennyson and Sir Walter Scott, who used numerous quotes from Crabbe's poems in his novels. During Scott's final illness, Crabbe was the last writer he asked to have read to him. Lord Byron admired Crabbe's poetry, and called him "nature's sternest painter, yet the best". According to critic Frank Whitehead, "Crabbe, in his verse tales in particular, is an important—indeed, a major—poet whose work has been and still is seriously undervalued." His early poems, which were non-narrative essays in poetical form, gained him the approval of literary men like Samuel Johnson, followed by a period of 20 years in which he wrote much, destroying most of it, and published nothing. In 1807, he published his volume "Poems" which started off the new realistic narrative method that characterized his poetry for the rest of his career. Whitehead states that this narrative poetry, which occupies the bulk of Crabbe's output, should be at the center of modern critical attention.
