Emanuel Swedenborg was a Swedish scientist, philosopher, theologian, revelator, and mystic. He is best known for his book on the afterlife, Heaven and Hell. Swedenborg had a prolific career as an inventor and scientist. (Wikipedia.)
I was commissioned by a close friend, Andrew Tischler, to do an illustration of Swedenborg. The robotic armor (playing off of the name SwedenBORG) and ethereal spirits are few of the personal touches I've added to the interpreted imagery.
