Piet Mondrian's Composition, 1916, is an abstract oil painting that represents a key transitional work in his artistic evolution, moving from representational subjects towards the radical simplification that would define his later Neoplasticism style. The painting, held by the Guggenheim Museum, features a grid of interlocking black lines and planes of ocher and gray, which originated from studies of a church facade and a tree. This work marks a crucial step in Mondrian's search for spiritual and universal harmony, which he sought to express through the balance of horizontal and vertical elements.
