Urizen appears within Blake's illustrations of Job as an image of Apollo. He and his realm are described in Blake's "Milton a Poem", and he is said to have a throne of silver/love. His realm included his children and was surrounded by justice and eternal science. The work also describes Urizen's Satanic fall. The Urizen of "Milton" is in the form of reason, and it is he that Milton follows. He appears again in the image "Milton's Dream" as illustrated for "Il Penseroso". In the image, Urizen is with images of despair and is interfering with the image of the true God.
