Art Glossary
A comprehensive glossary of art terms, techniques, movements, and materials. From chiaroscuro to creative coding, find clear definitions for every art concept.
C
Canon of Proportions: Ideal Human Measurement From Vitruvius to Leonardo
The canon of proportions is a system of ideal human measurements. From Polykleitos's Doryphoros to Leonardo's Vitruvian Man, learn how artists defined the perfect body.
Cartoon: The Full-Size Preparatory Drawing Behind Every Fresco and Tapestry
A cartoon is a full-size preparatory drawing used to transfer a composition to fresco, tapestry, or panel. From Raphael's Vatican Cartoons to Leonardo's drawings, learn how they worked.
Chalk: Natural Earth Pigments From Renaissance Drawings to Three-Crayon Technique
Chalk is a soft drawing material made from natural minerals: black shale, red iron oxide, and white calcite. Learn how Leonardo, Michelangelo, and Watteau used chalk and the trois crayons technique.
Charcoal: Carbon Drawing From Cave Walls to Contemporary Studios
Charcoal is burnt organic matter used for drawing since prehistory. Learn vine vs compressed charcoal, techniques from blending to fixative, and artists from Da Vinci to Kathe Kollwitz.
Conté Crayon: The Hard Pastel That Survived a Blockade
Conté crayons are compressed graphite or charcoal mixed with clay, invented in 1795 during the Napoleonic Wars. Learn how Seurat used them and why artists still choose them over soft pastels.
Contour Drawing: The Line That Describes Form
Contour drawing is the technique of rendering a subject entirely through its outlines, capturing form and volume without shading. From Picasso to Matisse, learn how it works.
Cross Hatching: Overlapping Line Sets for Darker Values and Deeper Form
Cross hatching is the drawing technique of overlapping sets of parallel lines to build darker values. From Durer to Rembrandt, learn how it creates tone and form.
G
Gesture Drawing: Rapid Drawing Capturing Movement and Essence
Gesture drawing is rapid drawing that captures the movement and essence of a figure. Learn its history, key practitioners, and how to practice it from Kimon Nicolaides to today.
Graphite: The Carbon Medium That Defined Modern Drawing
Graphite is a crystalline carbon used for drawing since the 1500s. Learn graphite grades from 9H to 9B, its Borrowdale origins, and how artists use it today.
Grid: The Measuring Tool That Makes Accurate Drawing Possible
The grid is a tool for transferring and scaling images accurately. From Alberti's veil to Durer's perspective machines to Chuck Close, learn its history and use.
P
Pastel: Pure Pigment Sticks From Leonardo to Degas and Beyond
Pastel is a stick of pure pigment held together with minimal binder. Learn how Degas layered pastels with fixative, how La Tour built portraits in the 18th century, and why pastel blurs drawing and painting.
Pen and Ink: Liquid Line Drawing From Quills to Technical Pens
Pen and ink is drawing with liquid ink applied through a nib. Learn about iron gall ink, quill and reed pens, steel dip pens, and how Rembrandt, Van Gogh, and Picasso used ink for permanent, expressive line.
Pencil: Graphite Drawing From Borrowdale to the Modern HB Scale
The pencil is graphite mixed with clay, encased in wood. Learn pencil grades from 9H to 9B, the history from 1564 Borrowdale graphite to Conté's clay process, and how artists use them.
S
Silverpoint: Metal Stylus Drawing on a Prepared Surface
Silverpoint is drawing with a silver stylus on a specially prepared surface, leaving delicate gray lines that oxidize to warm brown. Learn its history from Leonardo to today.
Stippling: Dots for Value, Texture, and Tone
Stippling is the art of building value and texture with dots. Learn its history from Renaissance engraving to scientific illustration and how it differs from pointillism.
Stump (Tortillon): The Rolled Paper Tool That Blends Drawing Media
A stump, or tortillon, is a rolled paper tool used to blend charcoal, graphite, and pastel. Learn the difference between stumps and tortillons, how to use them, and why they give artists precise control over tonal transitions.
T
Thumbnail Sketch: Small Compositional Studies Before Committing
Thumbnail sketches are small, rapid compositional studies that save time and prevent structural failures. Learn their history from Renaissance esquisses to concept art.
Tonal Drawing: Light and Shadow Masses Without Line
Tonal drawing builds form from patches of light and shadow rather than lines. Learn its history from Leonardo to Velazquez and how it differs from linear drawing.
Why an Art Glossary?
Art has always had a language problem. Walk into any gallery and you will hear terms like chiaroscuro, impasto, sfumato, and pentimento thrown around as if everyone knows what they mean. Most people do not. They nod along, afraid to ask, and miss half of what the painting is actually doing.
This glossary exists to fix that. Every entry is written in plain English with real examples: specific paintings, specific artists, specific dates. When we explain plein air, we point you to Monet working beside the Seine in 1873, not a generic definition copied from a dictionary. When we cover creative coding, we start with Casey Reas and Ben Fry at MIT in 2001, not a vague paragraph about "art and technology."
The terms here span centuries and disciplines. You will find Renaissance techniques sitting next to digital art movements, printmaking terminology next to motion graphics concepts. That mix is intentional. Art does not stay in neat historical boxes, and neither does the vocabulary we use to talk about it. A painter working today might need to understand glazing just as much as a 3D animator needs to know what kinetic typography means.
Each definition is a starting point, not a finish line. We write them to be specific enough that you can recognize the technique the next time you see it, but short enough that you can read one in under five minutes. If a term leads you to a painting you had not considered before, or sends you down a rabbit hole about a movement you had never heard of, the glossary is doing its job.
New terms are added regularly. If there is a concept you keep running into but cannot find here, that is a gap we want to fill. The best art terminology does not stay still. It grows as artists invent new ways of working, and the language has to keep up.
