Megaliths - A very large stone. 

2.) Representational - Descriptive of a work of art that depicts forms in the natural world. 

3.) Abstract - Descriptive of art in which the forms of the visual world are purposefully simplified, fragmented, or otherwise distorted. 

4.) Naturalistic - Descriptive of an approach to portraying the visible world that emphasizes the objective observation and accurate imitition of appearances. Naturalistic art closely resmebles the forms it portrays. Naturalism and realism are often used interchangeably, and both words have complicated histories. In this text, naturalism and realism are often used interchangeably, and both words have complicated histories. In this text, naturalism is construed as a broader approach, permitting a degree of idealization and embracing a stylistic range across cultures. Realism suggest a more focused, almost clinical attention to detail that refuses to prettify harsh or unflattering matters. 

5.) Trompe L'oeil - French for "fool of the eye," representational art that mimics optical experience so faithfully that it may be mistaken momentarily for reality. 

6.) Stylized - Descriptive of representational art in which methods for depicting forms have become standardized, and can thus be repeated without further observation of the real- world model. 

7.) Nonrepresentational - see nonobjective. 

8.) Nonobjective - Descriptive of art that does not represent or otherwise refer to the visible world outside itself. Synonymous with nonrepresentational. compare abstract, stylized. 

9.) Style - A characteristic, or a number of characteristics, that we can identify as constant, recurring, or coherent. In art, the sum of such characteristics associated with a particular artist, group, or culture, or with an artists work at a specific time. 

10.) Form - 1. The physical appearance of a work of art - its materials, style, and composition. 2. Any identifiable shape or mass, as a "geometric form". 

11.) Content - What a work of art is about, its subject matter as interpreted by a viewer. 

12.) Subject Matter - In representational or abstract art, the objects or events depicted. 

13.) Iconography - The identification, description, and interpretation of subject matter in art. 

14.) Context - The personal and social circumstances surrounding the making, viewing, and interpreting of a work of art;  the varied connections of a work of art to the larger world of its time and place. 

15.) Installation - An art form in which an entire room or similar space is treated as a work of art to be entered and experienced. More broadly, the placing of a work of art in a specific location, usually for a limited time. 

16.) Triptych - A composition consisting of three panels side by side, generally hinged in such a way that the outer two panels can close like shutters over the central one. 

17.) Contour Lines - The perceived edges of a three-dimensional form such as the human body. Contour lines are lines used to indicate these perceived edges in two-dimensional art. 

18.) Shape - A two-dimensional area having identifiable boundaries, created by lines, color or value changes, or some combination of these. Broadly, form. 

19.) Mass - Three-dimensional form, often implying bulk, density, and weight.

20.) Figure - see figure-ground relationship  

21.) Figure - ground relationship - In two-dimensional images, the relationship between a shape we perceive as dominant ( the figure ) and the background shape we perceive it against ( the ground ). Figure shapes are also known as positive shapes, and the shapes of the ground are negative shapes.  Pychologists have identified a list of principles we use to dicide which shapes are figures and which ground. When none of those conditions are met, our brain organizes the information first one way and then another, an effect known as figure-ground ambiguity. 

22.) Ground - 1. A preparatory coating of paint, usually white but sometimes colored, applied to the support for a painting or drawing. 2. An acid-resistant coating applied to a metal plate to ready it for use in etching. 3. The information that is perceived as secondary in a two dimensional image; the background. See figure-ground relationship. 

23.) Positive Shapes - See figure-ground relationship.

24.) Negative Shapes - See figure - ground relationship. 

25.) Model - In sculpture, manipulating a plastic material such as clay or wax to create a form. 2. In figurative drawing, painting, and printmaking, simulating the effects of light and shadow to portray optically convincing masses.

26.) Values - The relative lightness or darkness of a hue, or of a neutral varying from white to black. 

27.) Chiaroscuro - Italian for "light-dark." In two-dimensional, representational art, the technique of using values to record light and shadow, especially as they provide information about three-dimensional form. See model.

28.) Hatching - Closely spaced parallel lines that mix optically to suggest values. Hatching is a linear technique for modeling forms according to the principles of chioroscuro. To achieve darker values, layers of hatching may be superimposed, with each new layer set at an angle to the one(s) beneath. This technique is called cross hatching. 

29.) Cross Hatching - See Hatching. 

30.) Strippling - A pattern of closely spaced dots or small marks used to create a sense of three-dimensionality on a flat surface, especially in drawing and printmaking. See also cross-atching, hatching. 

31.) Refracted - The bending of a ray of light, for example, when it passes through a prism. 

32.) Color Wheel - A circular arrangement of hues used to illustrate a particular color theory or system. The most wellknown color wheel uses the spectral hues of the rainbow plus the intermediary hue of red-violet. 

33.) Primary Colors - A hue that , in theory, cannot be created by a mixture of other hues. Varying combinations of the primary hues can be used to create all the other hues of the spectrum. In pigment, the primaries are red, yellow, and blue. 

34.) Secondary Colors - a hue created by combining two prmary colors, as yellow and blue mixed together yield green. In pigment, the secondary colors are orange, green, and violet. 

35.)Intermediate Colors - Also known as tertiary colors. Colors made by mixing a primary color with a secondary color adjacent to it on the color wheel ( for example, yellow and orange). 

36.) Tertiary Colors -  See Intermediate colors. 

37.) Warm Colors - Colors ranged along the orange curve of the color wheel, from red through yellow. 

38.) Cool Colors - Colors ranged along the blue curve of the color wheel, from green through violet. 

39.) Palette - A surface used for mixing paints. 2. The range of colors used by an artis or a group of artist, either generally or in a specific work. An Open Palette is one in which all colors are permitted.  A restricted palette is limited to a few colors and their mixtures, tints, and shades. 

40.) Hue - The "family name" of a color, independent of its particular value or saturation. 

41.) Shade - A color darker than a hue's normal value. Maroon is a shade of red. 

42.) Intensity - The relative purity or brightness of a color. Also called chroma or saturation. 

43.) Chroma - See Intensity. 

44.) Saturation - see intensity. 

45.) Monochromatic - Having only on color. Descriptive of work which one hue - perhaps with variations of value and intesity - predominates.
