Diego Rodríguez de Silva y Velázquez (baptized June 6, 1599 – August 6, 1660) was a Spanish painter, an individualistic artist of the Baroque period (1600-1750), and the leading artist in the court of King Philip IV of Spain and Portugal and of the Spanish Golden Age.
His 1650 painting of Innocent X showed ruthlessness in his expression, according to some in the Vatican, and they feared Innocent would not like it. He was so pleased with the work that it hung in his official visitor’s waiting room.
“Francis Bacon (October 28, 1909 – April 28, 1992) was an Irish-born British figurative painter known for his raw, unsettling imagery. Focusing on the human form, his subjects included crucifixions, portraits of popes, self-portraits, and portraits of close friends, with abstracted figures sometimes isolated in geometrical structures. Rejecting various classifications of his work, Bacon said he strove to render ‘the brutality of fact.’ He built up a reputation as one of the giants of contemporary art with his unique style.” Wikipedia
Then, I located this YouTube video on Bacon.
The next video displays a genius at work and symmetry in art. A thing is the same on one side as on the other side, a mirror image of itself, on both sides of a center line.
