A line is an identifiable path created by a point moving in space. It is one-dimensional and can vary in width, direction, and length. Lines often define the edges of a form. Lines can be horizontal, vertical, or diagonal, straight or curved, thick or thin. They lead your eye around the composition and can communicate information through their character and direction.
Horizontal lines suggest a feeling of rest or repose because objects parallel to the earth are at rest. In this landscape, horizontal lines also help give a sense of space. The lines delineate sections of the landscape, which recede into space. They also imply continuation of the landscape beyond the picture plane to the left and right.
Vertical lines often communicate a sense of height because they are perpendicular to the earth, extending upwards toward the sky. In this church interior, vertical lines suggest spirituality, rising beyond human reach toward the heavens.
Horizontal and vertical lines used in combination communicate stability and solidity. Rectilinear forms with 90-degree angles are structurally stable. This stability suggests permanence and reliability.
Diagonal lines convey a feeling of movement. Objects in a diagonal position are unstable. Because they are neither vertical nor horizontal, they are either about to fall or are already in motion. The angles of the ship and the rocks on the shore convey a feeling of movement or speed in this stormy harbor scene.
The perfect illusion of three-dimensional space in a two-dimensional work of art is something that many artists, such as Pieter Saenredam, labored to achieve. The illusion of space is achieved through perspective drawing techniques and shading.
The surface of this writing desk is metallic and hard. The hard surface is functional for an object that would have been used for writing. The smooth surface of the writing desk reflects light, adding sparkle to this piece of furniture.
Intensity describes the purity or strength of a color. Bright colors are undiluted and are often associated with positive energy and heightened emotions. Dull colors have been diluted by mixing with other colors and create a sedate or serious mood. In this image the artist captured both the seriousness and the joy of the scene with the dull gray stone interior and the bright red drapery.
