What was Don Diego like? Explain.
Don Diego was a good man who lived for his art.
He was dignified and restrained (not given to huge shows of emotion) and cared mainly for his family, a few friends (including Juan and in a way the king), and his pets…and, again, his art. He was so dedicated to this art, which was his way of finding the truth of existence, that it dominated him. He could stand and stare for hours, just absorbing the sight of things, and as a painter he cared about things he didn't care about as a man (like the colors of fabrics and gems).
