A line can refer to many things but is essentially a continuous mark made on a surface by a moving point. It is a basic element of art that artists use to define space, create outlines and patterns, imply movement or texture, and allude to mass or volume. The type of line used, such as its weight and quality, can impact the mood and meaning conveyed by a work of art by describing textures, implying movement, or bringing certain elements forward while pushing others back.
