Faces in Profile

I recently had cause to think back to a trip to Florence, Italy, decades ago, and to Piero della Francesca’s “Diptych of Federico da Montefeltro and Battista Sforza” (c1465), which I had seen at the Uffizi Gallery. At the time, it was the fellow’s nose that caught my eye first. Not sure, way back then, I got far beyond that, other than remarking to myself on the effect of seeing the two facing off in profile.
