Objet d’art    French for “art object”, the term is used to refer to an artwork’s size, often diminutive or miniature.
Odalisque    Nineteenth century virgin female slave figures often found as attendants in Ottoman seraglios, they became popular subjects for artists who did Orientalist-theme paintings such as Frederick Bridgman, Francois Boucher, Hovsep Pushman and Jean Leon Gerome. While access to private homes or interior courtyards was difficult even for locals, artists such as Gérôme and Bridgman seemed to have succeeded better than many others in befriending locals enough to sketch and paint their domestic lives. In turn, fascination about this secret life of odalisques created a strong market for artists depicting them. Source: Abby M. Taylor, Fine Art; Wikipedia
Oeuvre    The total or substantive body of life-work produced by an artist, the term is French for “work”. Source:
Ogunquit Art Association, Maine    On September 16, 1928, Charles Woodbury called a group of artists together to form an art association for Ogunquit, which had become a major art colony. Joining Woodbury were Bernard Karfoil and Henry Strater. Woodbury served as the first president but Karfoli and Strater held back because of local perception it was a "leftwing radical" organization. Early active members included Charles Allen, Leon Bonnet, Elizabeth Sawtelle, and Gertrude Fiske. In 1929, members began selling their works at the Ogunquit Beach Pavillion, and in 1936, the Association moved to a yellow barn on Shore Road. From that time, the Association has been active with exhibitions, and education programs. Source: Louise Tragard, "A Century of Color, 1886-1986"
Ogunquit School of Painting and Sculpture    Opened in 1935 in Ogunquit, Maine, by Robert Laurent, it was a re-opening of what had been a summer art school run by Hamilton Field. Ogunquit School teachers and students had close connection to the New York art scene and shaped the art world of Ogunquit before and after World War II. Classes led by Laurent allowed much freedom and interaction with each other and the local environment; in fact students were not taught theory as much as they were taught a sense of independence of style. There were daytime and evening classes. Among teachers besides Laurent who taught stone cutting, modeling and wood carving were Bernard Karfiol and William von Schlegell, and Ernest Fiene for landscape and life painting. Elyot Henderson was an administrator. Students included Barnett Newmann. In the 1950s, the school began a slow decline, and it closed in 1962.

Oil Paint    Artists' medium, it is made by grinding pigment in linseed oil or another vegetable oil to a smooth paste-like consistency and then mixing in a drier, a stabilizer and plasticizer such as wax to give each color the same consistency. Since 15th century Europe, oil paint has been the most traditional medium, replacing tempera, because it results in rich coloration; dries slowly, allowing for changes; does not alter colors when dry; allows both opaque and transparent effects; and matte and gloss finishes. Today a group of western painters called Oil Painters of America actively promotes oil as a medium. Members include Howard Terpning, Roy Andersen, Joan Potter, George Carlson, Clyde Aspevig, David Leffel, Sherrie McGraw, Mian Situ and Ramon Kelley.

Oil Painters of America    Begun in 1991 and founded by Shirl Smithson, the group is dedicated to advancing the cause of traditional, representational painting and to providing a forum for artists working in that style. Several national and regional shows are held throughout each year. Members include David Leffel, Peter Adams, Ken Carlson, and Howard Terpning.

Old Lyme Colony,    One of many art colonies originating between 1890 and 1910 and devoted to landscape painting, it was in Old Lyme, a small village at the confluence of the Connecticut River and the Long Island Sound. The colony was first called “The American Barbizon” because of its founder, Tonalist-style painter Henry Ward Ranger. However, Ranger's stylistic influence was overshadowed by the 1903 arrival of Impressionist Childe Hassam, which resulted in the Colony becoming "the most famous Impressionist-oriented art colony in America” (Gerdts 221). To its detriment, Colony painters clung to that style after World War I when Impressionism lost its popularity. In its heyday, many painters stayed on Main Street at the Griswold House, a Georgian-style home of Florence Griswold, who took in boarders because she needed the income. Today it houses the Lyme Historical Society. Colony artists included Willard Metcalf, Clark Voorhees, Frederick Sexton, Charles Ebert, Walter Clark and Walter Griffin.

Old Master    A rather vague and very general descriptive term, it references skillful, fully-trained European artists who worked before 1800. The term has also come to be loosely applied to any revered deceased European artist of pre-modernist styles. Included as an Old Master are Leonardo Da Vinci (1452-1519), Rembrandt Van Rijn (1606-1669), Diego Velazquez (1599-1660), Titian (1483-1490), and El Greco. Source: Wikipedia; ASkART database

Oleography    Also called chromolithography, it was a method of coloring lithographs by preparing a separate stone for each color. As many as 30 stones were used for a single print. The method was pioneered in the 1930s with William Harring being a recognized pioneer of the method. By the 1860s, oleography was widely used for colour reproduction.

Online Art Market    Includes all art objects available to buy and sell online (computer technology), whether from galleries, auction houses, e-commerce companies, or online art platforms. Why It Matters: In 2018, the online art market grew 10% to hit a new high of $5.4 billion. This segment accounts for roughly 8.5% of the overall art market, which reached a total of $63.7 billion in sales in 2017, according to Art Basel and UBS’ 2018 Art Market report. One of the biggest advantages of the online art market is its ability to reach a vast number of collectors and connect them to galleries and auction houses across the globe. Since its emergence, the online art market has dramatically expanded the overall art market, increasing opportunities for selling and collecting art.

Online Art Platform    Also known as third-party marketplaces, they connect buyers and sellers around the world by enabling galleries, dealers, and auction houses to list their inventory online. Why It Matters: Today, more and more collectors are turning to online art platforms to engage with, discover, and collect art. Online art platforms, such Artsy, allow galleries to exhibit shows exclusively online, make sales when foot traffic is slow during the offseason, and connect with international collectors regardless of their location. As noted by Hiscox, the number of galleries partnering with online platforms is dramatically increasing. In 2018, three-quarters of galleries partnered with online art platforms to sell art online, an increase of 59% from 2017 and 41% in 2016. Additionally, galleries are becoming more and more reliant on these marketplaces to help them make sales—“19% of galleries are now using these marketplaces as an outlet for at least half of their online sales (up from 3% in 2017).

Online Buyer    A collector or prospective buyer who purchases art online, either through a third party platform or directly from a gallery or auction house’s website. Why It Matters: The emergence of a younger generation of art collectors has led to a rapid increase in the number of online art buyers, as collectors are becoming more comfortable buying works they have not seen in person. According to a survey conducted by U.S. Trust, millenials are currently the fastest growing segment of art collectors. Just this year, 78% of millennial collectors purchased art online, up from 69% in 2017. Additionally, the internet provides an opportunity for collectors to connect with galleries around the world, regardless of their location. Per the 2018 Hiscox Online Art Trade report, “70% of galleries this year sold their artworks online to international clients – up from 54% in 2017.” Source: '12 Online Art Terms to Know in 2018', Website of "Artsy", July 31, 2018
Online Sale    An online sale is “a sale where any part of the art sales process has an online element” (TEFAF Art Market Report: Online Focus). Similar to the means by which we assess Art Fair sales, if a user discovers an artwork on an online platform but then purchases the work from the gallery offline, the sale is still considered an “online sale” because the online platform facilitates the initial connection between user and gallery. Why It Matters: According to Hiscox, “52% of online buyers who bought art last year said they will be buying more art over the next 12 months.” Positioning your gallery in the online market introduces you to new collectors and increases your gallery’s reach, positioning you to take advantage of online sales.

Ontario College of Art, Ontario College of Art and Design University    Located in Toronto, Ontario, the school is tied to several entities, the first one being the Ontario School of Art, founded in 1879. In 1890, it became the Central Ontario School of Art and Design, the Ontario College of Art in the early 1900s, the Ontario College of Art and Design in 1996, and Ontario College of Art and Design University in 2008. The Ontario School of Art, founded in 1879 was an art school run by the local Board of Education. Under George Agnew Reid, teacher, principal and artist, it became a separate entity named the Ontario College of Art and moved into a building designed by Reid. Currently (2011) it is the largest art school in Canada, and operates under the name of Ontario College of Art and Design University.

Ontario Institute of Painters    The Ontario Institute of Painters [Canada] was devoted to the exhibition of non-abstract artists. It was formed in 1958 by traditional or representational artists, and their supporters who were disgruntled with the Ontario Society of Artists (see glossary) and the Royal Canadian Academy of Arts (see glossary) accommodation of abstract art. The OIP founders included Kenneth Forbes, Archibald Barnes, Manly MacDonald, Robert Allan Barr (see all previous in AskART), Gordon Conn (collector) and Samuel Weir (collector). Perhaps their most famous exhibition was “Points of View”, Museum London, Ontario in 1959. Then the works of 10 OIP members were hung with those of the abstractionist group Painters Eleven (see glossary) and figurative abstractionists like York Wilson (see AskART). The point of the show was to illustrate the conservative, experimental and intermediate trends in painting. Submitted to askART by M.D. Silverbrooke, West Vancouver, British Columbia.

Op Art    A short term for Optical Art, it is an abstract style popular in the 1960s and based on optical principles and optical illusion creating sensation of movement. Op Art deals in complex color interactions to the point where colors and lines seem to vibrate before the eyes. The term was coined in 1964 by George Rickey when he was talking with Peter Selz and William Seitz, curators at the Museum of Modern Art, and was first used in a publication in a 1964 "Time" magazine article to describe paintings "that manipulate visual cues in order to reorder viewers' perceptual responses." ("Southwest Art") Antecedents of Op Art go back to Josef Albers and his classes on color theory at the Bauhaus School in Germany during the 1920s. In 1965, the Museum of Modern Art gave the movement its most public attention to date with its exhibition, "The Responsive Eye". However, the uniqueness of the movement and popular interest subsided when fabric designers adopted it and made the optical designs commonplace. American Op artists include Julian Stanczak, Yaacov Agam, Richard Anuskiewicz, Larry Poons, Bridget Riley and Victor Vasarely.

Op-Ed Art    Characterized by black and white crosshatching and moody imagery, it was visual commentary and interpretation on editorials. John-Claude Suares, illustrator for "The New York Times", was one of the early Op-Ed artists. His goal was to get emotional reaction, and he and many he trained, used surreal symbolism. In 1973, the Musee des Arts Decoratifs in Paris hosted an Op-Ed art exhibit with a catalogue written by Suares. Source: AskART biography of Jean-Claude Suares including his New York Times obituary.
Optical Color Mixture    The tendency of the eyes to blend patches of individual colors placed near one another so as to perceive a different, combined color. Also, any art style that exploits this tendency, especially the pointillism of Georges Seurat. Source:

Orientalist/Orientalism    A 19th-Century movement, predominantly in France and England and reflected by American artists and writers, it reflected fascination with the cultures of North Africa, the Middle East and Asia. The geographical concept of most Orientalists was that the Orient was one vast region with a cohesive, uniform culture composed of rather simplistic, passive peoples. Much of the interest grew from western perceptions that these Eastern peoples were exotic, sensual, and attuned to mysterious religion and philosophy. The first Orientalists were 19th-Century English scholars who translated writing of the 'Orient' into English and French so that occupying westerners such as the English would have knowledge of the people they dominated. The period from 1870 to 1880 was a formative period for Orientalism among American artists, and general interest in Orientalism grew among western people with increasing travel opportunities. Fascination with Orientalism was expressed at the Chicago World's Fair of 1893 where Oriental villages were fabricated with snake charmers, Algerian dancers, odalisques and turbaned Moors. Artistic expression embraced many subjects including realistic and imaginary genre scenes, harems, landscapes, eroticism, and religion. The movement in art played out with the advance of Modernism such as Cubism in the early part of the 20th Century. Among Orientalist American artists are Henry Ossawa Tanner, Maurice Braun, Hovsep Pushman, Theodore Wores, Frederic Arthur Bridgman and Helen Hyde.

Origami    Origami is the Japanese name for the art of paper folding, and comes from the Japanese verb oru (to fold) and the noun kami (paper). The word "origami" is now commonly used around the world. An origami artist is usually called a paperfolder. The only requirement for origami is a piece of paper, making it one of the most accessible arts. Almost any paper may be used, but standard "origami paper" is thin, strong, and holds a crease very well. It is also usually white on one side and colored on the other side, and is cut into 15 cm squares (about 6 inches). The basic technique of origami is folding, and many complex folds have been developed. Many paperfolders enjoy folding models of animals (including all living creatures). Besides the many animal models, there are models of almost all physical objects including people, faces, plants, vehicles and buildings. Some paperfolders fold abstract or mathematical shapes, and others specialize in modular origami, where many copies of a simple folded shape are assembled to form large elaborate structures. Paperfolders are a diverse group of people ranging from artists to scientists to therapists. Artists and craftspeople use origami as a way to express themselves creatively. Scientists, architects, and mathematicians explore the geometry of origami for its own beauty and for practical applications. Therapists and teachers use origami as a tool to help their patients recover from illness or to help their students learn. Many people fold paper simply because it is fun. Origami artists include Akira Yoshizawa, a pioneer of origami, John Montroll, Robert Lang and Joseph Wu, whose website is the source of this information.
Orphism, Orphic Cubism    An abstract art movement from 1912 to 1914 in Paris, it paralleled the geometry of Cubism but with a brighter palette of overlapping planes of contrasting colors. "The color combinations were based on the 'law of simultaneous contrast of colors' developed by French chemist, Michel-Eugene Chevreul in the 19th century." The name, Orphism, also called Orphic Cubism, was taken from the Greek poet and musician Orpheus, and was first used in 1912 by the poet Guillaume Apollinaire to describe the paintings of Robert Delaunay. Other artists in the movement were Marcel Duchamp, Francis Picabia, Fernand Leger, Franz Kupka, and Sonia Delaunay, wife of Robert Delaunay. Source: World Wide Arts Resources
Ottawa Group    Canadian artists who organized in 1923 and held an exhibition the following year at Hart House at the University of Toronto, they appear to have disbanded the following year.

Outer Art    A movement dating from 1990 as a protest against random modern art, 'outer artists' asserted that anything could mean art. Focus is on making artwork that is ugly as possible, wrong as possible, and generally as impossible as possible. Outer-art was initiated by artist Florentin Smarandache, a Rumanian now living in Albuquerque, New Mexico. Source: AskART biography of Smarandache.
Outfootage    Outfootage, a filmaking term, it refers to footage mostly unprinted camera original but contains important information not included in the final film. Outfootage could also be found as a work print that ended up in the editor's bin. Source: Internet, Karl Spreitz Film Collection, Maltwood Museum.
Outsider Art     A term whose meaning is a bit vague, it has become a catch-all description of artwork not based on tradition and not marketed traditionally through galleries or private dealers. Outsider Art was first used publicly as a description in 1972 by British art writer Roger Cardinal in his book with that title. In this context, it is the equivalent of the French term "art brut", which means art of the insane. However, this description is subjective in that it often reflects the opinion of the viewer or critic and not necessarily a professional diagnosis. In the United States, Outsider Art is an umbrella term referencing artwork by creative persons outside the mainstream of society including prisoners and artists in psychiatric treatment. It also includes folk art that is memory painting, meaning dreams or fantasy depictions by non-academically trained artists. Names associated with Outsider Art include Martin Ramirez, Ike Morgan, Henry Darger, Steven Ashby, Joseph Yoakum and Ted Gordon.

Overbeck Pottery    Pottery produced in the midst of the Arts and Crafts movement in Cambridge City, Indiana, Overbeck Pottery was a family enterprise ceramics factory founded in 1911. It was run exclusively by the Overbeck sisters, educated women who had been raised to be independent, industrious and avoiding of marriage because it could thwart their potential: Elizabeth (1875-1936; Hannah (1870-1931); Margaret (1863-1911) and Mary Frances (1878-1955). In the book about the operation, "The Chronicle of a Studio Pottery”, Elizabeth Overbeck was quoted as saying that initially “No one concerned in the enterprise had any practical experience in clay working or was even personally familiar with the simplest of pottery making as carried on in a factory.” (59). Margaret Overbeck is credited as the main initiator of the operation, and the other sisters were already adept at china painting, having won many design competitions in a monthly pottery and decorator magazine. Before embarking on the business venture, Margaret and Mary studied with Arthur Dow, a leading figure in the Arts and Crafts movement. The same year the business opened, Margaret died, and the remaining three stayed the course with Elizabeth being the potter and firing technician, Mary painting, finishing and glazing; and Hannah doing the decorative designs, sometimes from sketches left by Margaret. The sisters lived simply, wore simple clothing and remained in the family home, using the parlor for a studio and another room as the showroom. The kiln was in a shed in the backyard. The early pieces were utilitarian such as cups and saucers, but the later work was more purely decorative. Most pieces are identified by the incised initials “OBK”, and sometimes to the left under the monogram is the first initial of the potter. In 1936, Elizabeth was elected a Fellow of the American Ceramic Society, making her the most publicly visible of the group. Eight months later she died, which brought an end to the unique enterprise as Hannah had died five years earlier. Mary carried on until her death in 1955, which ended the production of Overbeck pottery, whose formula went to the grave with Mary but whose pottery has become highly collectible. The production had numbered many thousands of pieces, and it was written that “their real genius lay in their complex Art Deco designs and subtle matte glazes . . . the sisters’ design contribution alone should secure their firm’s position as one of the best art potteries in the country”.
