Drawing

• 1. Introduction

  ›

  Drawing predates writing. Around 30,000 years ago, during the Art of the Upper Paleolithic, humans pressed marks onto cave and rock surfaces long before any written language existed. Those marks, called pictograms, carried both objects and abstract concepts. A drawing instrument does something quietly remarkable. It releases a small amount of material onto a surface and leaves a visible mark. From that single act flows a vast field. So how did simple lines on rock become both a fine art and the language of engineers? Why did a seventeenth-century argument about color and contour try to define what drawing even is? And what separates a person who draws accurately from one who cannot? The answers run through monasteries, telescopes, vanishing points, and studies of the human eye.

• 2. The Quarrel Of Color

  ›

  Leonardo da Vinci drew a distinction that would echo for centuries. He treated drawing as the contour lines of a subject, set against the colored surface and its modulations. That separation became a battleground. The seventeenth-century "Quarrel of Color" pitted proponents of color against those of drawing. In these debates, drawing was understood as independent of both technique and medium. It referred above all to the lines defining a form, not the hues filling it in. This was the moment drawing was conceived as an autonomous art form, aiming at nothing other than itself. The idea grew out of discussions among artists and art enthusiasts about the plastic qualities and principles governing painting. In Western terminology, drawing stayed distinct from painting even when the two shared media. Dry media like chalk could appear in pastel paintings. A brush could produce a drawing, where lines and hatching, rather than the tool, marked the work as a drawing. An underdrawing might even sit beneath finished paint on the same canvas. The boundary blurs further when colored-pencil work approaches painting, a tension the next aspect of this field makes physical.

• 3. Surfaces And Substances

  ›

  Silverpoint, gold, platinum, copper, brass, bronze, and tinpoint have all left their faint trace on a sheet. Metalpoint drawing usually employs either silver or lead, and these rarer metals turn up only occasionally. The medium is the means by which ink, pigment, or color reaches the surface. Most drawing media are either dry, like graphite, charcoal, pastels, Conte, and silverpoint, or carried in a fluid solvent, like marker, pen, and ink. Watercolor pencils bridge both. They can be used dry like ordinary pencils, then moistened with a wet brush for painterly effects. Very rarely, artists have even drawn with invisible ink. Paper carries most of this work, and it is not one thing but many. It ranges from newspaper grade up to high quality sheets sold individually, varying in texture, hue, acidity, and strength when wet. Smooth paper renders fine detail, while a toothier surface grips the drawing material and yields deeper contrast. Vellum is extremely smooth and suited to very fine detail. Bristol board and heavier acid-free boards resist distortion when ink or washes are applied. Acid-free archival paper holds its color and texture far longer than wood pulp paper such as newsprint, which yellows and turns brittle. The drawing board, pencil sharpener, eraser, circle compass, ruler, and set square round out the basic kit. One of those tools, the ruler, reappears later as a device for measuring proportion.

• 4. Marks And Tone

  ›

  Hatching is groups of parallel lines, the signature of many pen and ink drawings. Cross-hatching layers those lines in two or more directions to build a darker tone. Broken hatching uses lines with intermittent breaks to form lighter tones, and adjusting the density of the breaks produces a gradation. Stippling abandons lines entirely and uses dots to render tone, texture, and shade. Shading varies the tonal values on the paper to represent both the material's shade and the placement of shadows. Careful attention to reflected light, shadows, and highlights can yield a very realistic image. Blending softens or spreads the original strokes, and it works best with media that do not immediately fix, like graphite, chalk, or charcoal. A blending stump, tissue, kneaded eraser, fingertip, or a piece of chamois can all serve. Continuous tone is possible with graphite on a smooth surface without blending, though the technique is laborious, built from small circular or oval strokes with a blunt point. A light edge set next to a dark background stands out to the eye and almost appears to float above the surface. Subtractive drawing inverts the whole logic. The surface is covered with graphite or charcoal, then erased to reveal the image, a method that turns the eraser into a drawing tool.

• 5. The Illusion Of Depth

  ›

  Linear perspective makes dimensions shrink with distance on a flat surface. Each set of parallel straight edges of an object, whether a building or a table, follows lines that eventually converge at a vanishing point. That point usually sits along the horizon, since buildings rise level with the flat ground. When both the front and side of a building are drawn, a second vanishing point appears along the horizon, which may fall off the paper entirely. This is two-point perspective. Converging the vertical lines to a third point above or below the horizon produces three-point perspective. Depth does not depend on perspective alone. Objects of similar size should appear smaller the farther they are, so the back wheel of a cart looks slightly smaller than the front wheel. Texture compresses with distance, growing busy and taking on a different character than it would up close. Reducing the contrast and saturation of distant objects reproduces the effect of atmospheric haze, pulling the eye toward the foreground. Building a complicated shape such as a human figure starts simpler. Almost any form can be represented by some combination of the cube, sphere, cylinder, and cone, assembled into a likeness and then refined. That underlying construction is a fundamental skill for representational art, taught in many books and schools, and it leads straight into the deeper study of the human body.

• 6. Engravers And Old Masters

  ›

  Martin Schongauer, who lived from around 1448 to 1491, was the first Northern engraver known by name. He came from Alsace and was born into a family of goldsmiths. Albrecht Durer, a master of the next generation, was also the son of a goldsmith. With figures like these, drawing became significant as an art form around the late fifteenth century. Old Master Drawings often mirror the history and character of the country that produced them. In seventeenth-century Holland, a Protestant country with no King or court, there were almost no religious artworks, and most art was bought privately. Drawings of landscapes or genre scenes were viewed there not as sketches but as highly finished works. Italian drawings instead carried the influence of Catholicism and the Church, a major patron of art. French drawings often resembled the Italian, though in the seventeenth century the discipline of French Classicism made them less Baroque and less full of movement than their freer Italian counterparts. The twentieth century pushed in another direction. Modernism encouraged imaginative originality, and some artists turned less literal and more abstract. Pablo Picasso, Andy Warhol, and Jean-Michel Basquiat kept drawing at the center of their practice while reinterpreting traditional technique. Basquiat worked in ink, pencil, felt-tip or marker, and oil-stick, and he drew on any surface that came to hand, including doors, clothing, refrigerators, walls, and baseball helmets.

• 7. An Instrument Of Discovery

  ›

  In 1609, Galileo Galilei used observational telescopic drawings to explain the changing phases of Venus and the sunspots. Diagramming observations is an important part of scientific study, and drawing has long served as a method of discovery, understanding, and explanation. In 1924, the geophysicist Alfred Wegener used illustrations to demonstrate the origin of the continents. Before paper spread widely through Europe, monks in European monasteries drew on vellum or parchment, sometimes as underdrawings for illuminated manuscripts and sometimes as the final image. The wider availability of paper in the fourteenth century increased the use of drawing in the arts, where it became a tool for thought and investigation as artists prepared their final works. The Renaissance brought great sophistication to drawing techniques. It let artists represent things more realistically and revealed a fresh interest in geometry and philosophy. Then the first widely available form of photography shifted the hierarchy of the arts. Photography offered an alternative for accurately representing visual phenomena, and traditional drawing was given less emphasis as an essential skill for artists, particularly in Western society. Outside art, drawing kept a firm hold. Technical drawings or plans of buildings, machinery, and circuitry are still called drawings even after printing transfers them to another medium, and the people who make them are called drafters, draftsmen, or draughtsmen.

• 8. Why Some Draw Better

  ›

  John Ruskin was nearly convinced of a simple claim. In The Elements of Drawing he wrote, "For I am nearly convinced, that once we see keenly enough, there is very little difficult in drawing what we see." Investigative studies have tried to explain why some individuals draw more accurately than others. A visually accurate drawing is recognized as a particular object at a particular time and space, rendered with little added or deleted detail. One study identified four key abilities in the drawing process. They are the motor skills for mark-making, the drawer's perception of their own drawing, the perception of the object being drawn, and the ability to make good representational decisions. Motor control, the physical component of the production phase, has been suggested to play a role, though its effects are not significant. Perception appears far more decisive. A robust relationship between perception and drawing ability has been discovered, and this evidence formed the basis of Betty Edwards' how-to-draw book, Drawing on the Right Side of the Brain, which teaches drawing by developing the reader's perceptual abilities. Short-term visual memory matters too, since the gaze shifts between the object and the drawing. Decision-making sets artists apart in another way. Studies comparing artists to non-artists found that artists spend more time thinking strategically, including metacognitive activity such as weighing different hypothetical plans for how a drawing might progress.
