A few hundred years ago, the notions of heaven and hell, of God and Lucifer, were respected themes for composers, poets, and painters. Milton's Paradise Lost contains the idea of Lucifer endeavoring to defeat Christ and regain his former position in paradise. Raphael captured the epic battle where the Archangel Michael vanquished Satan. Beethoven wrote of the desire of man to know God.
And then, somewhere along the way, the devil became largely erased as a factor in popular culture. Any modern educated person who considers the battle between the forces of dark and the forces of light as anything but a mythical allegory is considered ... well, not modern today.
But of course, it still persists. The rumors of rock stars making the Faustian bargain still abound, the Rolling Stones had dire repercussions to Sympathy for the Devil at Altamont, and many modern pageants have demonic idolatry built right into their ceremonies.
So I think it's still relevant. Women and the Dark Side, today on Thinking with Somebody Else's Head.
