Frost at Midnight is a poem by Samuel Taylor Coleridge, written in February 1798. Part of the conversation poems, the poem discusses Coleridge's childhood experience in a negative manner and emphasizes the need to be raised in the countryside. The poem expresses hope that Coleridge's son, Hartley, would be able to experience a childhood that his father could not and become a true "child of nature". The view of nature within the poem has a strong Christian element in that Coleridge believed that nature represents a physical presence of God's word and that the poem is steeped in Coleridge's understanding of Neoplatonism. Frost at Midnight has been well received by critics, and is seen as the best of the conversation poems.
Frost at Midnight was written in February 1798 when he described to Thomas Poole aspects of his childhood at Christ's Hospital school that are similar to the content of the poem. The rest comes from Coleridge's experience with his friend, William Wordsworth. It was Wordsworth who provided Coleridge with a detailed description of the Lake District which served as a basis for Coleridge's description of the place. The relationship between Coleridge and Wordsworth was a close friendship, and Coleridge helped rewrite many of Wordsworth's poems during this time. Frost at Midnight was later connected to many of Wordsworth's poems. The poem was published in a small work containing his other poems France: An Ode and Fears in Solitude.
The poem was intended to be added to Coleridge's third edition of his collected poems, but a dispute with Charles Lloyd, a fellow writer, and Joseph Cottle, their mutual publisher, altered his plans. The poem was later collected in Sibylline Leaves, published in 1817 (see 1817 in poetry). It was rewritten many times, and seven different versions were printed. Of these revisions, the 1798 edition differs from the others in the final six lines, which were removed in later versions. Of this removal, Coleridge explains in George Beaumont's copy of the poems: "The last six lines I omit because they destroy the rondo, and return upon itself of the Poem. Poems of this kind & length ought to lie coiled with its tail round its head."
