Today's Daily Beast features an article on Irish painter Francis Bacon and an upcoming show celebrating the artists centennial at New York's Metropolitan Museum of Art. About Bacon:
Bacon's artwork is known for its bold, austere, homoerotic and often violent or nightmarish imagery, which typically shows room-bound masculine figures isolated in glass or steel geometrical cages set against flat, nondescript backgrounds. Bacon had begun painting by his early 20s. He painted sporadically and without commitment during the late 1920s and early 1930s, when he worked as an interior decorator and designer of furniture and rugs. He later admitted that his career was delayed because he had spent so long looking for a subject that would sustain his interest.
Since his death, Bacon's reputation has steadily grown. He still draws admiration and disgust in equal measures... (Wikipedia)
And from the Daily Beast article:
The ’60s and ’70s are arguably Bacon’s best years. He enlisted Vogue photographer John Deakin to photograph his coarse, creative group of friends, preferring to paint them from pictures, as he saw fit, in the solitude of his messy studio. Bacon crumpled and folded the photos to get new, distorted perspectives on the models’ faces, perhaps seeing them in their drunken states at the bar.
Bacon rivals Picasso in the way he represents the body, particularly the face. He defines the model’s nature, which is most often dark, through a combination of elegant marks. Everything is in motion,
