William Blake's 'Satan Watching the Caresses of Adam and Eve'

Question: in the illustration below for Paradise Lost, is Eve really looking at Satan?

Blake was remarkable for his then-radical ideas about “sexualized spirituality” and he belonged to a similarly-minded community of New Age free-thinkers and non-conformist religious sects. A debate rages to this day over just how weird it all got and the nature of the influences acting upon Blake: Swedenborg, the Moravian Church, the Quakers and Baptists, the Kabbalists, Tantric yoga and so on. At any rate, his executor and his descendants had to cover up erect penises and other dangerous objects in Blake’s illustrations, some of which have been restored to their original glory, but which do not appear in any public art galleries that I'm aware of. Early on in their marriage, when Blake and his wife Catherine were unable to have children, Blake suggested bringing in a concubine, but she was not enthusiastic and he dropped the idea.

A similar area where Blake was radical was in attacking racism and slavery. Consider the engravings below, from 1796. The first is Europe Supported by Africa and America, a wonderful gesture of unity between the three. The image below that is its complete opposite, a stunning condemnation of the horrors of slavery.

These illustrations appeared in a successful book by John Gabriel Stedman, a Dutch and Scottish army officer who served in Surinam: The Narrative of a Five Years Expedition against the Revolted Negroes of Surinam. It was first published in England in 1796 and was very successful, helping lead to the abolitionist movement. Blake's illustrations were a large part of that.

Cf. Blake's Songs of Innocence and of Experience: The Little Black Boy and Josiah Wedgwood's Am I Not a Man and a Brother anti-slavery medallion (both are 1787).
