It looks like an elogium of unBeauty to beauty. I don't know... this ugly face rise up thousand questions in my head and I could not resist to found out more. Why to paint such a face?... in fact, such a profile? It is the ugliest face I ever seen, without being wounded, or intentionally Grotesque. He is a natural ugly, proudly bearing all the scars of life.
The answers were overwhelming. Who was the Duke the Urbino (real name Federico da Montefeltro)?
Well, an amassing personage / personality of history. After I read all I found it I realize that it's missing image seen through the eyes of his wife, Battista Sforza (another strange, natural unbeauty personage)
