The Devil in Pharos Tarot is called the Lens. It’s the eye of the Lighthouse, gathering and focusing the light.
That beautiful glow is what I call a watercolor miracle. No other medium can capture light effects like it. Also, Phallus…of…Light! (said like “Pigs!In!Space!) Sorry but the muse likes to poke fun at me…it’s actually made hilarious derogatory names for most of my paintings lately.
