I've always been into Classicist paintings. My favorite painters are William Adolphe Bouguereau, Lawrence Alma-Tadema, John William Godward, Albert Joseph Moore, and many others. I have many books on Classicist art in my private library, but my most prized possession is:
"The world is my country; all of humanity are my brethren; and to do good deeds is my religion." (Thomas Paine)
