Working with line in drawing can often mean simplifying shapes. In his work Dove with Flowers, Pablo Picasso uses just a few lines to simplify a bird to its most basic shape. Defining diagonal lines in drawings can show depth in space. In his work, Francois Gauzy, Henri de Toulouse-Lautrec uses lines to move the viewer’s eye from the foreground to the background of the drawing. Lines can also be used to depict three-dimensional forms on a flat picture plane, as seen in the work of Albrecht Dürer. Fernand Léger uses cross-hatching to develop the shapes of hands and feet in his Foot and Hands. American artist Loïs Mailou Jones uses varied line weight to develop the figures in her dynamic drawing Men Working.
