I would absolutely say that this is the weakest Blake work I’ve encountered so far. It’s a mythological poem that functions as a critique of the Christian idea of marriage; Blake was very spiritual in his own way and Jesus was a significant figure in that spirituality, but the one thing he couldn’t abide in Christianity was the ban on sexual activity. In this poem, a villain rapes a woman and her husband refuses to stand up to try to protect her. The poem ends with them all basically in a bad way, crippled by guilt and/or betrayal. It’s . . . just pretty bland. 2 stars.
tl;dr – Blake critiques Christianity’s view of sexuality, but the poem is bland and forgettable, one of his weakest. 2 stars.
