Crucifixión by Roberto Matta is a painting from 1938. It is made of oil paint on canvas and measures roughly two feet tall by three feet wide. It is hung in landscape orientation, meaning its longest side runs parallel to the ground. This painting is an example of an abstraction, which is a style of painting that focuses on the gestural movement of shapes and colors rather than depicting scenes or figures. The painting is formed with a foundation of dark colored paint that serves as the backdrop for the rest of the abstract shapes that seem to hover above it. This foundation is primarily black but has tones of red, blue, and green throughout that slightly change the tonality of the black color. Above this foundation is a long streak of paint that is grey/green in color. It weaves itself around the painting and because of the gradient of shadows on it, gives the impression of a large fabric moving within the canvas. At three points in the painting: the top left, directly underneath it in the bottom left, and toward the middle right, there are irregular shapes that are red, brown, yellow, and white in color. At the top right above one of the red shapes, there is a yellow circle.  All of the shapes vary in their tonality, giving the feeling of movement and variation in light.
