"Night" is a poem in the illuminated 1789 collection Songs of Innocence by William Blake, later incorporated into the larger compilation Songs of Innocence and of Experience. "Night" speaks about the coming of evil when darkness arrives, as angels protect and keep the sheep from the impending dangers. Songs of Innocence was written by William Blake in 1789 as part of his Illuminated Books. Blake's aim for his Songs was to depict the two contrary states of human existence: innocence and experience. The Songs speak upon the "innocence" of being a child and the "experience" gained over a lifetime. The Songs are separated into ten different objects, with each object offering a different situation and how it is viewed from a child's perspective. Source: Wikipedia (en)
