To be honest, I pack all my realistic pictures into one container. I also know some really good masculine painters. But my field is Catholic Art and I read the gospels more now than ever. The Jesus story is very, very big in art. Yes, catholics know Jesus in art, music and literature ... very well. The study is bigger than my head. Wiki helps with way, way too much data and I simplify. U get what I remember. If I could leave u with just one picture, it is The School of Athens.
