The poem Lamb is taken from Song of Innocence in william blake's poetry collection Song of Innocence and Experience, and is often compared with the famous Tiger in Song of Experience. It is not only a rare form of praise and criticism, but also depicts the mental state of human beings in the industrial age with two different animals. Lamb, child and him are recurring images in poetry. Blake's etched paintings for this poem show children and a group of lambs, and the poem unfolds in the form of dialogue between children and lambs. Children and lambs are symbols of innocence and religion, while "He" is the creator and God.
