First of all, the action line represents the figure’s flow of motion. This is particularly important in portraying cats. Artists experienced in capturing a cat’s movement in drawing begin their composition doodling with waves of lines on their paper or canvas, trying to imagine a suitable movement or action for their figure. Finding the right line of action is crucial to their drawing as they consider it the “mother of all foundations.”

To artists, a lines of action is never be complicated, lest it makes the figure awkward and mangled. Bear in mind that cats move, and shall always be expected to move, in a very graceful manner that when captured on film and viewed frame by frame, it would be like the cat were posing for a magazine cover or centerfold. Do also consider the fluidity of the cat’s movement. The gracefulness of its movement seems to provide an uncanny feeling of predictability, that you almost always know what it is going to do next, except that this understanding is based on your feeling, as if you yourself were the cat. A cat glides through an unbroken sequence of what may seem to be a pre-scripted motion. Notice this difference when observing birds. Birds are nervous and jerky, and will not stand still.

Cat artists will explain that there is a unique excitement derived from drawing cats, and it begins in finding the right line of action. While it is true that the line of action fundamentally determines the motion pose for any figure (human, for example), with the cat, the line easily becomes the figure. Usually, an action line appears as a pencil streak across a blank drawing field where a figure is later built upon. For the human figure, it is a vertical or diagonal line, slightly curved in representing its spine; for cats, it is many times horizontal but more bent like the current of a wave of water. The sprinting image of a cheetah, for example, with its all its legs up in the air, may begin with an action line that looks like a representation of an AC power stream. A kitten captured in a pouncing frolic over a yarn may basically look like diagonal overextended S.

An action line is a line of discipline. It controls the artist’s concept and the way a spectator sees the figure. Its straightforwardness facilitates an easier organization of the figure’s details as the stages progress; it will also aid to a trouble-free understanding of the figure when it is later viewed.

As there are secondary markets in the trade of goods or wares, there is a secondary market in the trade of art. The great difference is that art doesn’t depreciate with age, even if subject to wear, and that prices on the secondary art market aren’t determined by singular usability but by their universal desirability. What we understand by a primary and a secondary market in the art trade is important for our appreciation of the monetary value of a work of art. When an artwork comes to the market for the first time at a gallery or any other art exhibition we speak about the primary market. This is the moment when the price for the artwork is established for the first time. The artist, or the gallery owner / dealer in conjunction with the artist, establish a selling price based on art market indicators at the time of presentation. As with any commodity market, the mechanism of “supply and demand” defines this pricing structure.

Once the artwork is purchased on the primary market and the buyer, whether a private collector, an institution or a dealer, decides to resell it, it enters the secondary market. Most items sold through auction houses form part of the secondary market, as the artwork has already been purchased at least once. Secondary market trade means trade in art that is not coming directly from the artist. As in many other trades there is a great amount of speculation in the commerce of art. Some prices asked on the primary market inevitably raise dubitative questions as to longevity. However, such considerations matter little for the primary market’s dynamism; strongly sustained by marketing artefact, sales technique, fashionable trends and not least, by the Vanity Fair that is art collecting.
