Piet Mondrian first treated the theme of the sea in naturalistic works of 1909–11, during lengthy sojourns in the village of Domburg on the coast of Dutch Zeeland. He assimilated and adapted the Cubism [more] of Pablo Picasso and Georges Braque in Paris soon after his arrival there in the winter of 1911–12. He returned to the Netherlands in the summer of 1914 and probably in the following war years worked on the studies of the sea that culminated in the Pier and Ocean paintings of 1917.

The oval format and grid structure used in these works are devices derived from Cubism. They serve respectively to resolve the problem of the compositional interference of the corners and to organize and unify the picture’s elements. For Mondrian the horizontal-vertical arrangement did not have an exclusively pictorial function, as it did for the Cubists, but carried mystical implications. He viewed the horizontal and vertical as basic oppositional principles that could interact to produce a union symbolizing a state of universal harmony.

Although Mondrian’s source exists in the natural world, in the motion of waves and their contact with breakwaters, the signs for this source have been reduced to their most essential pictorial form. The strokes are determined by their structural function rather than their descriptive potential, and there is no sense of perspectival recession despite the atmospheric texture of the gouache highlighting. This highlighting evokes the reflection of light on water and also defines planar surfaces. As Mondrian developed the theories of Neo-Plasticism, these suggestions of natural phenomena disappeared.
