While poking around on the Laurentian Library yesterday, I came across a 2014 paper on the history of how people tried to make sense of Michelangelo’s puzzling reality: the classical orders he violated, mathematical composition and proportion, and anthropomorphy. Which, given the Vitruvian principle that the ideal proportion is the human body, was sort of the same thing.

But I was surprised to see the argument lead off with this drawing from the Casa Buonarotti of column bases with a human face in them. Or so I was told.
I stared at the base on the left in lowkey disbelief. Michelangelo was really out here hiding a stunned Beetle Bailey profile in his architecture, and this is how I find out about it? Should we tell everyone? Should we throw a party? Should we invite Jasper Johns?

No, we should not invite Jasper Johns; he was already here. Reading the Casa Buonarotti curator’s notes on the drawing, I realized I’d been looking for a Johns vase-style negative profile instead of a Michelangelo caricature-style profile, which is in the base on the right:
in his imagination, the upper molding takes on the appearance of a turban, while the base profile transforms into a screaming human face, to which are added, in a caricatured manner, an eye, a nose, and a gaping mouth (for further considerations on this sketch and its possible connection with the Vitruvian idea of ‘architectural anthropomorphism’, cf. ELAM 2012, pp. 94-95, [which I cannot find, btw, but it’s not important now. -g.o]).
But at least it led me back to Johns’s seemingly disjointed but ultimately insightful 2007 interview with John Yau in The Brooklyn Rail:
Yau: It seems to me that some of your motifs, such as the ones of the faces in profile/vase, are irritating because one sees either the faces looking at each other or the vase between them, but never both at the same time. There is a continuous frustration in the looking. The figure and ground keep changing places, and one becomes aware that one never sees this image in its entirety. The feeling I get from this motif is both satisfying and maddening. Why does this conundrum hold interest for you?
Johns: I am not certain that one can’t see both at once. Has someone who knows about the eye and the brain made a determination?
Not only can I see both of Michelangelo’s faces at once, I couldn’t unsee them if I wanted to.
After Yau works through years of accumulated questions [which, ngl, very relatable now. I should call him. -g.o], there’s an actual [sic] dialogue for a minute, about different aspects of Johns’s use of the term “helpless,” and suddenly:
Yau: Is the helpless behavior of a material, the puddling of the ink when used on plastic, for example, one of the parallels between art and life?
Johns: I imagine that our understanding of the behavior of materials is closely related to our understanding of the rest of what we think of as reality.
