radial, radiate, and radial balance - Radial means anything of, relating to, or arranged like rays.

Radial or rotational balance is any type of balance based on a circle with its design extending from or focused upon its center. see thumbnail to leftA star, the iris around each pupil of your eyes, a wheel with spokes, and a see thumbnail to rightdaisy (among many flowers and other plant forms) are examples of radial balance.

The Temple of Jupiter was the principal religious structure of ancient Rome. This rosette was apparently carved stone. Although this architectural feature may have been polychromed in its original state, the colors in this engraving are highly speculative. The enlarged view includes a cross-section of the rosette. This engraving is one of a set of 100, some of which can be purchased from lombardmaps.com. See Roman art.

radiate - See ray.

 

 

radiograph - An image produced by radiation other than visible light, especially by x-rays passed through an object or by photographing a fluoroscopic image, on a radiosensitive surface, such as a photographic film. Radiographs are sometimes made of art objects to better see what is beneath their surfaces, in hopes of revealing information about their making, and alterations over time. Typical examples are radiographs of mummies, and of paintings that have been painted over, are in need of conservation, or are suspected forgeries.

radius - A straight line from the center of a circle to any point on its circumference, or from the center of a sphere to any point on its surface, and the length of any such line. Also, a long, slightly curved bone, the shorter and thicker of the two forearm bones, located on the lateral side of the ulna. The plural form can be either radii or radiuses. Double the radius and you have the diameter.

rasp - A coarse and abrasive tool made of metal (usually steel). The abrasive surface has many pointed teeth shaped like tiny pyramids, and typically the surrounding surface is perforated so that dust doesn't clog it. Rasps are used in shaping and smoothing wood, plaster, ivory, stone, etc. Files are generally more finely abrasive than rasps, while rifflers are the most finely abrasive of all rasps.

Also see surform.

 

 

 

raster image - See bit-mapped image.

 

 

rathas - In Hindu tradition, small, freestanding temples, perhaps sculptured as architectural models.

 

 

ratio - The relationship between two or more similar things in size, number, or degree. The numerator and denominator of every fraction function in this way. For example, "1/2" represents the ratio between one and two: one of two equal parts that together make a whole. 3/6 and 50/100 are similar ratios. Ratios are often expressed as numbers separated by a colon, and read as "is to." Analogies are often made using ratios. An example is 50:100 as 1:2. Ratio is essential to scale and proportion, and to the particular type of proportion known as the Golden Mean.

rational - Consistent with or based on reason; logical. This is relative to several factors, including context; as, for instance, in a culture whose thinking is classical, idealizing, or scientific.

 

 

rattan - A plant, and all materials derived from it — primarily cane and reed — have been used largely in the production of baskets and wicker furniture. It is obtained from such areas as as China, Southeast Asia, Malaysia and the Philippines. Its earliest use in basketry has been dated to the third millennium BCE. Rattan has been used as the framework for wicker furniture since the mid-19th century, although most wicker from the 1870s-1940s was made with a wooden structure.

Rattan is both a vine and a palm, known to grow along the ground and up into jungle trees, reaching lengths of up to 600 feet and diameters of up to four inches. Rattan has a thorny bark that must be removed to reveal the inner skin, from which cane is made, with a naturally glossy surface. Reed comes from the pithy core of rattan.

Also see bamboo, dowel, raffia, and rush.

 

 

 

ray - A thin line or narrow beam of light, or a representation of such a straight line. A structure or part having the form of a straight line extending from a point; and when there are several such lines extending from one point, they may be said to radiate from that point, as points radiate from a star.

rayograph - In the work of Man Ray (American, 1890-1977), a photogram.

 

 

Rayonism - A type of abstract or semi-abstract painting characterized by the fragmentation of forms into masses of slanting lines. It was practised from 1912-1914 by Natalya S. Goncharova (Russian-French, 1881-1962), Mikhail Larionov (Russian-French, 1881-1964), and a few other Russian painters. Larionov's manifesto on Rayonism stated that it is a synthesis of Cubism, Futurism, and Orphism." Aspects of each of those isms can indeed be seen in Rayonist paintings — Cubism's breaking up of forms, Futurism's movement of forms, and Orphism's rich color. In addition, the Rayonists expounded a theory that objects emitted invisible rays which the painters could manipulate to their own purposes. "The rays which emanate from the objects and cross over one another give rise to rayonist forms. The artist transforms these by bending them to his desire for aesthetic expression." Goncharova and Larionov often applied the paint in their Rayonist works with palette knives.

Also called "Rayonnism," "Rayism," and, in Russian, "Luchism."

rayonnant - The "radiant" style in thirteenth century architecture that is associated with the royal Paris court of Louis IX (1214-1270), the French king also known as Saint Louis.

 

 

readability - In typography and any written text, the degree to which it is legible. In any text, very rarely is the need to convey a style more important than it is to communicate its meaning. Although lettering should be attractive, readability is usually the most important factor in its design.

realia - Material culture, or objects from real life, in contrast to those objects typically included in a collection. A piece of realia draws attention either because it is a common example of its kind — as an exemplum rather than as an exemplar or because of associations with its previous owner. Some such objects might also be described as artifacts, ephemera, bric-a-brac, gewgaws, found objects, or memorabilia, but they are seldom prized for any qualities of their design, for their fine materials, or for the craftsmanship with which they were made.

Realia includes objects used by educators to help students to understand other cultures and real life situations. A teacher of a foreign language employs realia to strengthen students' associations between words for everyday objects and the objects themselves. Examples might include an apple, a shoe, a menu, a fork, a door, etc.

A library is more likely to prize realia for its associations with writers, subjects, or themes in the library's collection of media. The library at Yale prizes Eugene O'Neill's lighter, while Sir Arthur Conan Doyle's golf clubs gather dust at the U of Texas. The Bertrand Russell Archive at the McMaster U in Ontario hangs on to two Vietnam-era cluster bombs, deactivated but genuine. Such realia is akin to relics, memorabilia, and souvenirs. (What bookman wouldn't be thrilled to accession Ernest Hemingway's fishing rod or William Shakespeare's eraser! [Do you suppose he had one?!])

There is no singular form for this word, because realia refers to a group of or classification of things.

rectilinear and rectilineal - Moving in or forming a straight line. Also, characterized by straight lines. "Rectilinear" comes from the late Latin "rectilineus," which itself comes from the Latin words "rectus" ("straight") and "linea" ("line"). "Rectilineal" is a synonymous form of this word. Because "rectilineal" remains far less popular than its relative, writers might as well avoid it unless there's a need to rhyme with anneal.

(pr. REK-tə-LI-nee-ər and REK-tə-LI-nee-əl)

A term that is distantly related to rectilinear is "rectitude," the formal, dignified bearing adopted by proctologists.

 

 

recto - The front side of any work on paper. May also be the right-hand page of a book. The opposite of verso. The front and rear sides of other two-sided objects, such as coins, medals, or panels which have a painting on each side are more often referred to as obverse and reverse.

Also see numismatics.

reduction firing - A method of producing greater depth of color on a clay body by firing ceramics with reduced oxygen in the kiln.

 

 

reed - A natural, fibrous weaving material used in the production of baskets and wicker furniture. The inner pith of the rattan plant is called reed. Its grain makes its appearance similar to a wood. Reed has a certain brittle quality. It comes in various dimensions. Reed is more porous than cane, and will accept a stain, paint, lacquer or varnish.

Also see bamboo, cane and caning, furniture, raffia, and rush.

 

 

reflected color - The color perceived from an object, determined by the wavelength of the light leaving its surface after selective absorption of other wavelengths of the incident light the light hitting the surface. Reflected light behaves in certain ways that differentiate it from colors produced by sources of the light. The concept of reflected color is related to that of subtractive color — color produced by mixing cyan, yellow and magenta pigments, each of which absorbs certain wavelengths. A balanced mixture of these colorant or subtractive primaries theoretically yields black since it absorbs all wavelengths of visible light.

Also see additive, local color, optical mixing, and primary colors.

 

 

reflection, reflected image - An image given back by a reflecting surface, such as that of a mirror or still waters. Each ray of light that hits a surface is an incident ray of light. Rays that are neither absorbed, nor reflected, are scattered rays of light. A person sees a clearer reflection when a high number and percentage of rays are reflected, and a small number of rays are either absorbed or scattered.

refraction

 

refraction, refract - Refraction is the change in direction which occurs when rays of light pass from one medium to another of a different density, as they do from air to glass or water. Or, the distortion of an image by seeing through a translucent medium. To refract is to cause such a change in the direction of light. Ophthalmology is concerned with the eye's refractive ability: changing the direction of light in order to focus it on the retina. An ophthalmologist measures this refractive ability, resulting in an accurate prescription for lenses which will optically compensate for the eye's inability to achieve focus.

Also see angle, mother-of-pearl, point of view, reflection, refractory, telescope, and wavelength.

 

 

refractory - Resistant to high temperatures. Refractory materials are used for molds in lost-wax casting and for kiln furniture on which ceramic ware stands while it is fired.

Also see refraction.

 

 

Regency - Refers to one of the periods during which a person or group has been selected to govern in the place of a ruler who is either absent, disabled, or too young to govern. In England, this is the style of design prevalent during the regency from 1811-1820, of the future George IV. An example is Paul Storr's (English, active 1785-1838) Centerpiece, 1810-1811, silver with mark: date letter P, width at base: 18 x 14 inches, Birmingham Museum of Art. Among the French, it refers to the style prevalent during the regency from 1674-1723, of Philippe, Duc d'Orleans.

 

 

 

Regionalism or regionalism

 

 

register, register mark, and registration - The exact alignment of shapes or edges in various areas of any piece of work. In printmaking, registration is the proper positioning of plates or colors. Any mark made to assist in positioning elements for better alignment can be called a register mark, registration mark, reg mark, or an alignment mark. In museum work, registration is the process of developing and maintaining an immediate, brief, and permanent means of identifying an object for which the museum has assumed responsibility.

In this case, a white margin will remain once the page has been cropped. See graph.

 

Also see accession, bleed mark, ear, fold, graphic design, and registrar.

 

 

registrar - A person with broad responsibilities in the development and the enforcement of policies and procedures pertaining to the acquisition, management and disposition of collections. The registrar maintains the records pertaining to the objects for which the institution has assumed responsibility. Usually the registrar also handles arrangements for accessions, loans, packing, shipping, storage, customs, and insurance as it relates to the objects.

Also see art careers, curator, museology, museum, preparator, register, and typology.

 

 

regular - Uniformly or evenly formed or arranged. Circles, squares, and equilateral triangles must all be regular shapes. Some ovals and some quadrilaterals are regular. No amorphous shapes or biomorphic forms can ever be regular.

Also see straight.
