M
Marble: The Metamorphic Stone That Defined Western Sculpture
Marble is a metamorphic limestone used for sculpture since ancient Greece. Its translucency and workability made it the preferred material for carving from the Parthenon to Michelangelo's David.

Planographic Printing: The Flat Surface That Changed Printmaking
Planographic printing prints from a flat surface using chemical separation, not carved depth. From lithography to offset, learn how it works and why it matters.
Portrait Photography: The Photographic Portrait From Nadar to Catherine Opie
Portrait photography uses the camera to capture the human face and presence as art. From Nadar and Cameron to Avedon, Arbus, and Opie, learn its history and masters.
Propaganda Posters: Political Persuasion as Visual Art
Propaganda posters use graphic design for political persuasion. Learn their history from WWI to Soviet propaganda to contemporary Ukrainian resistance posters, key artists, and techniques.
S
Shape: The Two-Dimensional Building Block of Visual Art
Shape is a flat area surrounded by edges or outline. From Mondrian's geometric grids to Matisse's organic cut-outs, learn how shape works in art.
Silver Gelatin Print: The Standard Black-and-White Photographic Print
The silver gelatin print is the standard black-and-white photographic process of the 20th century. Learn its history, chemistry, and why it defined fine art photography.
Solarization: Partial Image Reversal in Photography
Solarization is the partial reversal of photographic tones caused by re-exposing a developing image to light. Learn its history from Sabatier to Man Ray and Lee Miller.
Sound Art: Sound as Primary Medium in Contemporary Art
Sound art uses sound as its primary medium, from Max Neuhaus to Christina Kubisch. Learn its history, key artists, and how sound became a gallery art form.
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
The Sublime: Overwhelming Awe Beyond Beauty (Burke, Kant, Friedrich)
The sublime is the aesthetic experience of overwhelming magnitude or power that produces awe mixed with terror. From Burke to Kant to Friedrich, learn the concept.

Typography is the art of arranging type and letters. Learn its history from Gutenberg to variable fonts and generative typography exhibitions in 2026.
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.
