Blake's Tyger

Among Blake's Songs of Experience is a poem called The Tyger, which is placed in opposition to The Lamb, from Songs of Innocence. Among a multitude of commonly studied and analyzed poems, The Tyger is interpreted here as "an intriguing moral critique of Protestant Christianity, or more specifically, a theological query into the motivations of Creation itself."

Blake frequently used the image of the Lamb referring to the Lamb of God (Jesus!) In contrast the carnivorous Tyger has an obvious association with Satan. So he's posing the age old question "did God create the Savior and the Devil." Blake emphatically questioned it and disbelieved it to the point of denial. He stated it later in this picturesque way:
" Thinking as I do that the Creator of this World is a very Cruel Being & being a Worshipper of Christ I cannot help saying the Son O how unlike the Father First God Almighty comes with a Thump on the Head Then Jesus Christ comes with a balm to heal it"
(Description of the Last Judgment Erdman 565)

If you were not already aware how radically Blake's theology diverges from 'conventional religion', this should certainly convince you. The Lamb and the Tyger, or similar metaphors oppose one another throughout Blake's myth until eventually Satan can be perceived as a State rather than a Person, a state that can be happily annihilated as Time ends, passing into Eternity.
