The photos of the frescoes don't do justice to the remarkable illusion conveyed but the painting. I have never seen a painting this convincing, where I knew (after being told by Yoko) that the architectural elements of the ceiling were in fact simply painted on, but still didn't quite believe it. Apparently, I am in good company: Yoko related the story of a famous artist who remained stalwartly unconvinced. But be assured: everything you see (save for the few gold ornaments) is painted.
A curious and fascinating element of the Villa Farnesina is the graffiti left by the invading armies from the north in 1528.
