This work is dedicated to Thomas Alva Edison, inventor of the electric lightbulb; Thales of Miletus who is recognized for coining the term electricity and his approach to explain the world by naturalistic theories rather than by mythology; and last but not least to popart icon Andy Warhol, famous for overcoming traditional concepts of fine art.
As you can see very easily, this work is designed as a triptych which is typically for religious artworks because of it’s connection to the christian concept of Trinity. In this context the bulb is representing a symbol for God (who is sometimes religiously referred as The Light). Since the Age of Enlightenment the old metaphysical idea of God gets more and more replaced by a new one, which is grounded on technical and economical convictions rather than on ethics or spirituality.
One could argue that the christian Trinity of Father, Son and Holy Ghost is nowadays fully replaced by science, the market and the media.
