Minerva leads a group of weeping figures towards a giant urn of this man's remains, while a beam of light passes above a statue's hand, in a painting of an "allegorical monument" to this person by Giovanni Pittoni. A proposed monument to this person is based on two circular pedestals ringed with cypress trees, and has a grand staircase leading to a chamber whose roof holes correspond to the constellations. A 500 ft diameter sphere is the centerpiece of that "cenotaph" to this man, which was depicted in a series of engravings by Etienne-Louis BoullÃ©e. This man sits naked on an algae-covered rock outcropping and bends over to (*) draw on a scroll with his compass in a monotype by William Blake. This man's theories were challenged in a treatise that influenced Runge and Turner, Goethe's Theory of Colours. For 10 points, name this man who influenced art theory with a treatise that demonstrated that prisms could split light into a spectrum of colors, Opticks.
