E to E M



E.A. - The abbreviation for the French term épreuve d'artiste, meaning artist's proof.



ear - In casting, a depression that receives a pin for aligning the pieces in a two-piece mold. Pictured here is a two-piece rubber mold in which a jeweler can cast a wax ring to be used in lost-wax casting. An ear can be seen at each corner of the right half of the mold.

Also see concave, dent, mortise, register and register mark.




earth art and earthworks



earth colors - Pigments, such as yellow ochre and umber, that are obtained by mining; usually metal oxides.

Also see color, color wheel, and warm colors.








earthworks - See earth art.






ecce homo - The title commonly given to depictions of Christ as he was presented to the crowd for crucifixion. Latin for "Behold, the man." The story of Pontius Pilate is told in various books of the Bible. The 'Ecce homo' episode is from John 19:5. Matthew 27:24. "When Pilate saw that he was doing no good, indeed that a riot was impending, he took some water, washed his hands before the crowd and said, "I am innocent of this man's blood. It is your affair."

(pr. ET-chay HOH-moh)

eccentric - Literally, not having the same center, and figuratively, departing from the typical or established norm or pattern, heterodox. A person who deviates markedly from an established norm, especially one exhibiting odd or unconventional behavior — off-center. It can also be used to describe something that doesn't follow a truly circular path, as in "an eccentric orbit." "Eccentric" contrasts with "concentric": having a common center; concentric circles are placed one within another.

Two Venn diagrams present examples of sets of eccentric shapes:

educator, teacher



effigy - A likeness or image, especially of a person. A likeness of a deceased person, when placed on his tomb, is usually called an effigy. Now, more often a crude figure or dummy of someone despised; a symbolic image of a person. Perhaps this latter sense arises from a wish that the subject were dead.

efflorescence - A formation of white crusty material — crystals resulting from penetration of moisture through painted walls — especially brick, tile, or uncoated plaster. It may also be produced by soluble material present in the wall itself.

Also see bloom and patina.



effort - Mental or physical energy used to achieve a purpose; self-discipline. A person's exertions to reach a particular goal or overcome particular difficulty. At minimum, effort is attempting to accomplish something. Sometimes an effort is remarkable because it is something someone is trying to do for the first time.

In science, effort is synonymous with energy, and can be measured. In the arts, although effort — the exertion of energy — is essential, it is less tangible than the end result. The art world is typically interested in artists' intentions, but more so in artists' achievements. No collector acquires the "trying" unless it is palpable. When effort is particularly apparent, art critics and historians dwell on those exertions, and might speculate on them when they are not apparent. Although conceptual art might seem to be an exception to this rule, ultimately the quality of what any artist has done relies on that which can be seen in the work itself — its making, its production, its success.

 Art educators might assess students' efforts as much as they do their achievements. Effort is more difficult to observe well enough to quantify it. Unless a student displays extraordinary challenges, basing an assessment on effort alone devalues and invalidates that assessment, and may be counterproductive and unethical. Pressure to assess the efforts of able students without assessing their achievements may come from students, their families, or other educators. Their arguments might be:

Art disciplines are somehow different from other disciplines.

Yes, the art disciplines are different in several important ways — ones that put the study of art at the heart of our students' education. Nearly every student who enrolls here and exerts energy can and should achieve great things. Not everyone does. But our expectations are not inappropriate — they're specific to what successful students should achieve.

Some students have no interest in becoming artists. Art should primarily be uplifting / amusing / recreational / therapeutic.

Art should be much more than entertainment. The best art has a habit of being the most interesting art. Even more important: art is basic. As we motivate students, simultaneously we pursue many other goals. Just look at our school's / state's / nation's fine arts standards. All of our students need to understand that they are expected to do their best, and that they are most likely to achieve to their potential when they give it their all -- when no one makes excuses for them. There are already so many things interfering with their learning!

But talent isn't distributed equally, and some or all students are required to (or non-art-majors would like to) enroll in art.

If this argument is valid, it could be made for students of any discipline! Every educator here works with every student he gets. (The "talented" ones are in there with everyone else. Or they just learn differently.)

If you don't give higher grades, fewer students will enroll in art classes, and you won't have a job.

When an educator inflates grades, respect for standards collapses as the program becomes a haven for non-achievers.

A joke:

A flood was threatening a town, forcing everyone to evacuate. But Joe was thinking, "I'm a devout man; God will save me," and he stays put. As the waters rise, Joe's neighbor comes by and says, "Joe, come with me. we've got to go." Joe declines: "I'm a devout man. God will save me." The waters keep rising. Joe scrambles to his second floor. A firefighter in a rowboat paddles by. "Get in the boat or you'll drown," he says. Joe again declines, saying, "I'm a devout man. God will save me." Finally, the flood waters force Joe to his roof. A police helicopter comes by and throws down a rope. "Climb up or you'll drown," the policeman yells. "No," Joe replies, "I'm a devout man. God will save me." But soon Joe drowns. When he arrives in heaven, Joe challenged God, "Why didn't You help me?" "What do you mean?" God says. "I did help. I sent a neighbor, a firefighter, and a helicopter."

elitism and elitist - The belief that certain persons deserve favored treatment by virtue of their superior artistic or intellectual accomplishments, or because of some other real or perceived status. People and things reach various levels of achievement, of success, and for better or worse, people judge the qualities of other people and things. But elitism is a tendency to codify levels of artistic sophistication into a hierarchical system that some would call pretentiously exclusionary, and others realistic. Elitism is the sense of entitlement that follows from this attitude, and the control or dominance by a group of elitists — the people who take this view of their position. Elitism always elicits aesthetic questions about defining art, who is an authority about it, and what that means for people who aren't.

Elitism in the art world is the insistence that art is somehow out of the realm of common experience, that its pleasures are not available to everyone. It has become increasingly necessary to read texts (artists' statements, wall labels or plaques, articles of art criticism, etc.) in order to understand certain works of art, but this is what great contemporary art does: It advances through ideas, by engaging our minds. Art galleries, because their offerings are commodities, are invariably commercial enterprises, but they are among the only places where the public can see art free of charge. Museums serve comparable roles as a community's storehouse of art, exhibiting works to their vistors, educating visitors to the works' significance, garnering support in ways unlike the galleries'. Wherever encounters with art occur, they always demand the viewer's attention and receptivity. Failure to embrace those opportunities are at least, simply that: losses of opportunities, significant as those can be.

"Thomas More (1477/78­1535), humanist scholar, author, and statesman, served Henry VIII as diplomatic envoy and Privy Councillor prior to his election as speaker of the House of Commons in 1523. The chain More wears in this portrait is an emblem of service to the King, not of any specific office. In 1529 More succeeded Cardinal Wolsey as Lord Chancellor, but three years later he resigned that office over the issue of Henry's divorce from Catherine of Aragon, and subsequently he refused to subscribe to the Act of Supremacy making the King head of the Church of England. For this he was convicted of high treason and beheaded. Venerated by the Catholic Church as a martyr, More was beatified in 1886 and canonized in 1935 on the four-hundredth anniversary of his death." — notes from the Frick Collection.

A way of combining elements to stress the differences between those elements and to create one or more centers of interest in a work. Often, emphasized elements are used to direct and focus attention on the most important parts of a composition — its focal point. Emphasis is one of the principles of design. A design lacking emphasis may result in monotony.

Emphasis originated in the root of the Greek word emphainein, to exhibit or display.

In the 1920's Demuth produced a series of poster-portraits honoring his contemporaries, inspired by Gertrude Stein's word-portraits. The Figure 5 in Gold is the most accomplished of the group. It was dedicated to the artist's friend William Carlos Williams, the American poet whose "The Great Figure" inspired the painting's title and imagery. Demuth's painting, however, is not a representational illustration of the poem but rather an abstract impression of the No. 5 fire engine clanging through the lamp-lit streets of the darkened, rainy city. Scattered words and initials refer to the artist and the poet. The number "5" is emphasized by repeating it, by varying the thickness of the line with which it is drawn, and by making its largest version so very large. See Futurism and text.



see thumbnail to rightRobert Minor (American, 1884-1952), Pittsburgh, 1916, lithographic crayon and India ink, published in The Masses, no. 8, August 1916. Robert Minor produced this drawing as an editorial cartoon, commenting on a 1916 steel workers' strike. He emphasized the thrust of the soldier's bayonet by drawing its direction as the counterpoint to that of the worker's body. The grace of this juxtaposition results in our feeling all the more shock at the sight of the pointed blade. Minor drew inspiration for this approach from such European masters as Francisco Goya and Honoré Daumier, coming to produce such spare, forceful drawings as this. See movement, Realism, Romanticism, and social realism.
