in. - Abbreviation for inch.
inanimate - Neither moving nor having other qualities associated with living organisms.
inch - A unit of distance measurement equal to 1/12 of a foot, or 1/36 of a yard. To convert inches into centimeters, multiply them by 2.54. To convert square inches into square centimeters, multiply them by 6.4516. To convert cubic inches into cubic centimeters, multiply them by 16.3871. A unit of measurement equal to a thousandth of an inch is a mil. Inch is abbreviated in. or with a " (feet is abbreviated as ft. or with a ').
incident light - The light hitting an object's surface, not that reflected or scattered from it. The wavelength of incident light is usually more varied than that reflected from a surface, determining the colors perceived in the object. It undergoes selective absorption of some wavelengths as it is reflected. The law of reflection is a principle that when light is reflected from a smooth surface, the angle of incidence — the angle at which the light hits a surface — is equal to the angle of reflection, and the incident ray, the reflected ray, and the normal to the surface all lie in the same plane.
Also see additive, mirror, optical mixing, primary colors, and subtractive.
incising - Cutting into a surface, typically in metal, stone, or pottery, often used for lettering and decoration. An example is a Tablet which has an incised glyphic inscription, Mexico: state of Guerrero, Ahuelican, Highland Olmec, Middle Formative period, 900-500 BCE, greenstone, 3 1/2 x 3 1/2 x 3/4 inches, Dallas Museum of Art.

incoherence, incoherent - The opposite of coherence, coherent.
incongruity - A state of two or more things lacking harmony, being incompatible, inconsistent, absurdly combined. Such things would be described as incongruous. This sometimes results in irony. What makes something humorous or tragic is essentially an instance of incongruity. Incongruity is an idea explored often by artists influenced by Dada and Surrealism.
René Magritte (Belgian, 1898-1967), The Treachery [or Treason] of Images, 1928-9, oil on canvas, 23 1/4 x 31 1/2 inches, private collection, NY. "Ceci n'est pas une pipe," means "This is not a pipe." See Surrealism.

Salvador Dalí (Spanish, 1904-1989), Lobster Telephone, 1936, plastic, painted plaster and mixed media, 17.8 x 33.0 x 17.8 cm, Tate Gallery, London. This sculpture is a classic example of the Surrealist practice of juxtaposing otherwise unrelated everyday items. The Surrealists valued the mysterious and provocative effect of such incongruities. Dalí believed that his objects expressed the secret desires of the unconscious, and that lobsters and telephones reveal the prominence of the sexuality.
Scott Mutter (American, 1944-), Untitled (Forest), 1975, gelatine-silver print photomontage, 11 x 14 inches, American Museum of Photography. This forest has a parquet floor. "While others use the techniques of photomontage for shock effect, Mutter creates worlds that can best be described as 'hyper-realistic.' "

incrustation - Also called "masonry," incrustation is a style of classical Roman wall decoration in which the wall was divided into bright, polychrome panels of solid colors with occasional, schematically rendered textural contrasts, often veined in imitation of polished slabs of marble (see marbling). Of the few Roman paintings that survive, most are frescoes from the area of Campania in the vicinity of Naples, including Pompeii, Herculaneum, and other towns whose people, art and architecture were destroyed and preserved for us by the eruption of Mount Vesuvius in 79 CE. Domestic interiors were windowless and dark, giving Romans a need to visually enliven them. First produced in the 3rd century BCE, incrustation was the earliest of four styles of Roman wall paintings which have been identified.
Roman, Wall in the House of Sallust, Pompeii, 3rd century BCE, fresco, in situ.
A reconstruction of how it may have originally looked and
how it looks today.
The second style — "architectonic" — from early in the 1st century BCE, included the use of linear perspective, creating the illusion of windows looking onto scenic landscapes. The third style — "ornamental" — first employed during Augustan's rule at the end of the 1st century BCE, flattened the wall again with sets of pictures as in a gallery, some effecting trompe l'oeil. The fourth style is a composite of the earlier three, in use during the 1st and 2nd centuries CE.
incubation - The name used first by Jacob Getzel (American psychologist) for the third stage in the creative process: mulling over the problem in a sort of chaos of ideas and knowledge, letting go of certainties (forgetting); engaging the intuitive, non-sequential, or global thinking at the core of creativity. This is what some call "breathing room" or "downtime." Although we appear to be most productive when we actively pursue our goals, and a sense of urgency can be as speeding as a healthy eagerness, the most creative amongst us must prepare for this stage of work by giving our imaginations time to dwell upon a situation, indirectly as well as directly, dreaming about it in a seemingly idle way. Beware of attempts to remove such incubation periods from any schedule of creative pursuits.
Also see memory.
index - A recording of an event produced by a connection between an object and its role in the event. In semiotics, as presented by Charles Sanders Peirce (American pragmatist, 1839-1914; pr. purse), there are three kinds of signs: icon, index and symbol. Whether a sign belongs in one category or another is dependent upon the nature of its relationship between the sign itself (which Peirce called the referent) and its the actual meaning. An icon is a meaning which is based upon similarity or appearance (for example, similarity in shape). According to Pierce, icons are "the only means of directly communicating an idea." An index is a meaning based upon some cause and effect relationship: "Because the indexical sign is understood to be connected to the real object, it is capable of making that object conceptually present."
The plural form of this word is indices. The adjectival form is indexical.
Examples of indices:
Thermometers carry a certain meaning because of variation in temperature.
Footprints carry certain meaning because of their associations with specific creatures.
One reason Action Painting was significant was its practitioners' assertion that its indexical nature — the painter's brushstrokes as expressive of his/her activity.
Examples of Action Painting:
Franz Kline (American, 1910-1962), Merce C, 1961, National Museum of American Art, Washington, DC.

Index of American Design - A New Deal art program that hired numerous artists to produce more than 18,000 watercolor renderings of American decorative arts objects from the colonial period through the nineteenth century, including costumes, dolls, folk arts of the Spanish Southwest, furniture, metalwork, Pennsylvania German folk art, pottery, Shaker crafts, textiles, toys, and woodcarving. The Index of American Design was one of the projects between 1935 and 1942 of the Section of Painting and Sculpture (SPS), later known as the Section of Fine Arts (SFA) in the Treasury Department of the U.S. government. Much or all of the Index is now in the collection of the National Gallery of Art, Washington, DC. Tours of the Index of American Design are available as slide programs from the National Gallery's Department of Education Resources: Free Loan Programs.
India ink or Indian ink - The name in the United States for black ink, the pigment made from carbon — traditionally lampblack (derived from non-electric lamps). This ink is also used in solid forms, mixed with a binding agent and molded into cakes or sticks. Such solid forms are often called Chinese ink, Japanese ink, or sumi ink.

Also see pointing.
indirect casting - Lost-wax metal casting in which the model that is "lost" is not the original model, but a wax cast from a piece mold taken from the original model. This second wax model is sometimes called an indirect casting, or an intermodel. If the indirect casting is hollow, a core is pored into it. The ancient Greeks developed this method of casting.
Indirect casting has numerous advantages because it:

Also see achievement, effort, tactile defensiveness, and VSA arts.
inert - Stable, unable to move or act at all, or sluggish in motion. In chemistry, not readily reactive with other elements; thus forming few compounds. Inert substances and materials are not easily decomposed or otherwise modified chemically, which is a particularly desirable characteristic for materials used in art conservation. Acid free papers and cardboards, for example, are more inert than acidic ones, so they degrade much more slowly; they are less likely to become discolored and brittle over time or upon exposure to various conditions during use or storage.
Also see hypoactive.
inflatable - A sculpture or other object made with a plastic or PVC film or fabric which achieves its intended form when filled with air or some other gas.
Paolo Lomazzi, Donato D'Urbino and Jonathan De Pas, manufactured by Zanotta S.p.A., Italy, Blow Inflatable Armchair, 1967, polyvinyl chloride (PVC) plastic, inflated: 33 x 47 1/8 x 40 1/4 inches (83.8 x 119.7 x 102.9 cm), Museum of Modern Art, NY. See furniture.
Jeffrey Shaw (Australian, 1944-), with Theo Botschuijver (Dutch), Waterwalk, 1969, air structure event, tetrahedron shaped balloon made from transparent (and sometimes colored) plastic, height 3 m. A watertight zipper allowed people to enter and be sealed inside. When this lightweight structure was inflated with air, one or more people could "walk on water" by stepping and rotating it like a wheel over the water surface. The large volume of air in the balloon allowed the occupants some time for their journeys — and whenever they wished they could simply unzip themselves out. Lakes, rivers and the sea were the venues of what the artist calls an "eventstructure." See Happening and performance art.

infrared - is coming soon
infrared reflectography (IR) and reflectogram - Infrared reflectography (IR) is used to examine the surface of the ground layer of any painting, even when it is covered by one or many layers of paint. The result of the IR technique is a black and white photograph called a reflectogram. Such images permit art historians to read the underdrawings beneath the paint. This is possible because light in the near-infrared region of the spectrum (wavelengths from about 1 up to 2 microns) easily passes through the paint, to be reflected by the marks used to make the underdrawing. Reflectograms allow a researcher to obtain information about the painter's drawing media and techniques, and even to find and read hidden writings. These might include signatures and dates sometimes covered by earlier restorations. Reflectograms occasionally reveal artists' earlier versions of their compositions (pentimenti), and even sketches of things not visible in the painting as it is seen today. Reflectography is often used by restorers and conservators. In many cases it improves analysis of the creative development of the artwork and reveals pieces of previous restorations. Reflectograms were first made in the early 1930s, when the technique was called "IR photography." Various improvements to IR since then have led to a digital version of the technique — an infrared scanner is connected to a high-powered computer. This advance has made possible far more useful images than ever before, because more gradations of value are now achieveable.
Matteo di Giovanni (Italian), detail of The Virgin with Child and Saints, in color and in the IR reflectogram. This painting was executed for the Cathedral of Pienza.

initial letter - See capital letters and historiated.
inkblot or ink blot - An image formed by dripping ink onto a piece of paper, and then folding the paper in half. Inkblots are invariably symmetrical, but making them is largely aleatoric, their shapes depending greatly upon accident or chance. Painted versions of inkblots are called blotto painting. In psychology, inkblots have been used in the Rohrschach test (an example). Also see blot.
inlay - Making an image by setting thin pieces of a material precisely into a depressed ground. Examples of materials typically inlaid are wood, metal, stone, shell, glass, ivory and tile. Also, a piece of work made this way.

inpaint - In art restoration, to repaint a damaged or missing portion of a painting in order to return the artwork to visual harmony. There may be other treatments necessary in a painting's restoration which should precede the point at which inpainting is appropriate. Preparatory stages might include stabilizing the support and its surface, and filling areas of lost paint to raise the depth of any gap between the support and the surface of surrounding paint. This filling material may need to be textured to match the original paint surrounding it. It may also be necessary to apply several layers of color in order to precisely match the surrounding paint. Inpainting should be carried out with conservationally sound materials, easily reversible and distinguishable from the original. In order to detect inpainting in an old painting, carefully examine it under both white and ultraviolet (UV) light. Although the value of old and new colors may be identical under white light, because recently applied paint absorbs UV, infills will appear to be darker than otherwise matching original paint. See art conservation and lacuna.
inscribe and inscription - To mark as with letters or numbers, often a short label, as an artist might formally mark his name, a title, the year, a dedication, etc. Such a label can be called an inscription.

Each of these three scripts were being used in Egypt at the time it was carved. An officer of Napoleon's engineering corps found the stone half buried in the mud near Rosetta, a city near Alexandria, in 1799. Carved on the stone is a decree by Egyptian priests to commemorate the crowning of Ptolemy V Epiphanes, king of Egypt from 203 - 181 BCE The Stone is an icon of script and decipherment.

insouciance - Breezy lack of concern; nonchalance.
inspiration - Somebody or something that stimulates a person to a high level of feeling, to creative thought, or to achieve the making of art. Inspiration may be the condition or quality of being stimulated to creative thought or activity. A sudden brilliant idea. To those who are religious, inspiration may be divine guidance and influence on human beings. To inspire someone is to fill that person with confidence and motivation; an inspired person feels that he or she can achieve something difficult or special.

insula - In Roman architecture, a multistoried apartment block.
intaglio - The collective term for several graphic processes in which prints are made from ink trapped in the grooves in an incised metal plate. Etchings and engravings are the most typical examples. It may also refer to imagery incised on gems or hardstones, seals, and dies for coins, or to an object decorated in this way; which when pressed or stamped into a soft substance, produces a positive relief in that substance.
An example of an intaglio in the second sense:

Also see glyptic and numismatics.
intarsia - Inlay work, primarily in wood and sometimes in mother-of-pearl, ivory, bone, marble, etc. This may result in either pattern or picture. To construct intarsia, outline drawings are used as templates for cutting many pieces of thin material. The cut pieces are glued onto a sturdy support. In a wooden intarsia, many types of wood provide the different colors used. Sometimes stains, bleaches, or heat were applied to the wood to provide a wider range of tints, tones, and shades. The English word "intarsia" came from the Italian "lavoro di intarsia."
Fra Giovanni da Verona (Italian), Intarsia Illusion of Cupboards, two pairs of panels of wood intarsia, 1520: Each conveys the appearance of open cupboard doors — a trompe l'oeil effect resulting from the use of linear perspective. The first panel: a Campanus sphere, a mazzocchio, and various instruments of the geometer.
The second panel: a complex polyhedron which can be constructed by erecting a pyramid of equilateral triangles on each face of an icosidodecahedron. These first two panels are in the Monastery of Monte Olivetto Maggiore, near Siena, Italy.
The third: the Campanus sphere again, along with an icosahedron and a truncated icosahedron.
The fourth: a cube with equilateral pyramids erected on each face, a cuboctahedron, and again the elevated icosidodecahedron. The second two panels are in the church of Santa Maria in Organo, Verona.

intensity - The brightness or dullness of a hue or color. For instance, the intensity of the pure color blue is very bright. When a lighter or darker color is added to blue, the intensity is less bright, or more subdued.
Also see saturation, shade, tint, tone, and value.
intercolumniation - In architecture, the space or the system of spacing between columns in a colonnade.
interdisciplinary - Involving two or more artistic, scientific, or other academic disciplines. While exploring a concept, issue, or theme, interdisciplinary studies adopt methods and theories from different fields of study, often within an academic context. Artists have produced numerous interdisciplinary works since the early 20th century, and more so since the onset of postmodernism. Emblematic of this trend has been the breakdown of boundaries between such categories in art as painting and sculpture, between painting and theater, between drawing and cinema. Examples of interdisciplinary synthesis can be found among combine paintings, works by Fluxus artists, conceptual art, earth art, environment art, and performance art, among many others. New media is perhaps the latest such example. The visual arts have many traditional interdisciplinary connections with mathematics and the sciences, architecture, design, music, philosophy (empiricism, epistemology, metaphysics, ontology, phenomenology, semiotics, teleology, etc.), history, archaeology, anthropology, ethnology, psychology, technology, manufacturing, and many other fields.
Concepts having interdisciplinary aspects include abstraction, analogy, cartography, chronology, civilization, culture, elegance, entropy, ergonomics, feminism, horology, kinesthetic, knowledge, measurement, metallurgy, metamorphosis, mind, model, mystery, ophthalmology, optics, order, pattern, periodicity, photography, simplicity, space-time, structure, transformation, typology, and unity.

interior design - The planning and realization of the layout, furnishing and decoration of an architectural interior. Sometimes called interior decoration, but preferred to that term, because of decoration's more superficial goals.
Also see design and furniture.
intermedia - See mixed media or mixed-media.
intermediate colors - Also known as tertiary color, they are produced by mixing unequal amounts of two primary colors. For example, adding more red to the combination of red and yellow will produce the intermediate color of red-orange. Intermediate colors are located between the primary and secondary colors on a color wheel. Other intermediate colors are orange-yellow, yellow-green, green-blue, blue-violet, and violet-red (also known as purple) — all colors in the spectrum except violet-red — a mixture of the two colors at the extremes of the visible spectrum.
intermodel - See indirect casting.
International Council of Museums (ICOM) - An international organisation of museums and museum professionals which is committed to the conservation, continuation and communication to society of the world's natural and cultural heritage, present and future, tangible and intangible. Created in 1946, ICOM is a non-governmental organisation maintaining formal relations with UNESCO and having a consultative status with the United Nations' Economic and Social Council. As a non-profit organisation, ICOM is financed primarily by membership fees and supported by various governmental and other bodies. It carries out part of UNESCO's programme for museums. Based in Paris (France), the ICOM Headquarters houses both the ICOM Secretariat and the UNESCO-ICOM Museum Information Centre.
The 17,000 members of ICOM in 140 countries participate in the national, regional and international activities of the organisation: workshops, publications, training, twinning programmes, and the promotion of museums through International Museum Day (May 18, annually). The membership participates in the activities of 115 National Committees and 29 International Committees. Some National Committees have also organised on a regional level to reinforce their action.

iris - Physically important in sight, a circular band of muscles that controls the size of the pupil. The pigmentation of the iris gives "color" to the eye. Blue eyes have the least amount of pigment; brown eyes have the most.

irony, ironic - Irony is a form of expression in which the real meaning is concealed or contradicted by the words or images used — a meaning which either markedly contrasts or is entirely opposite to that which appears to be presented. It is a trope in which there is an incongruity between what might be expected and what actually occurs. Irony involves the perception that things are not what they seem to be. The intention of one who uses irony is usually to imagine that there are two kinds of people in the audience: the first kind will not understand that what they see does not carry the ultimate meaning, and the other is aware that there is more meaning intended, and also that the first kind of person doesn't understand this. Irony is a means of expressing an attitude which is disguised by what what will seems to be obvious. The effect of irony is usually intended to be humorous, dramatic, tragic, insulting (sarcastic), or absurd. Irony is essential to satire. When irony is presented by pretending ignorance, is is the kind also called "Socratic irony." "Ironic" is the adjectival form: relating to, characterized by, using, or containing irony.

isocephaly - The arrangement of figures so that the heads are at the same height.
Also see hieratic.
issue - An issue is often a point or matter of discussion, debate, or dispute. Some issues of great interest in the art world may be eternal, while others come and go from time to time. There are always issues concerning aesthetics and metaphysics, the opposing pressures of tradition and change, art's relationships with other disciplines (see interdisciplinary). The word "issue" is often used as a general reference to problematic circumstances that draw upon the common disciplines of knowledge, such as sociology, economics, ethics, and literary criticism. In recent years, among the issues important to artists have been conceptual art, environmentalism, feminism, gender, multiculturalism, xenophobia, commodification, mass media, and postmodernism.
Further examples of issues can be found in the contexts of articles about cultures, periods, movements, and styles.
Also see art criticism, genre, interdisciplinary, isms and -ism, meaning, quality, semiotic, subject, theme, and theory.
italic - In typography, slanted letters. They were first produced in 1506 by the Italian designer Aldus Manutius, who slanted letters to give words special emphasis. Italics now have much the same purpose: adding force to certain words and setting off titles from surrounding text. Here, the first line of text is plain, but the second line is italic.
