A STILL LIFE is a work of art depicting inanimate subject matter, typically commonplace objects which may be either natural (flowers, game, sea shells and the like) or man-made (drinking glasses, foodstuffs, pipes, books and so on). Popular in Western art since the 17th century, still life paintings give the artist more leeway in the arrangement of design elements within a composition than do paintings of other types of subjects such as landscape or portraiture. Still life came into its own in the new artistic climate of the Netherlands in the 17th century. While artists found limited opportunity to produce the religious art which had long been their staple—images of religious subjects were forbidden in the Dutch Reformed Protestant Church—the continuing Northern tradition of detailed realism and hidden symbols appealed to the growing Dutch middle classes, who were replacing Church and State as the principal patrons of art in the Netherlands. Especially popular in this period were vanitas paintings, in which sumptuous arrangements of fruit and flowers, or lavish banquet tables with fine silver and crystal, were accompanied by symbolic reminders of life's impermanence. A skull, an hourglass or pocket watch, a candle burning down or a book with pages turning, would serve as a moralizing message on the ephemerality of sensory pleasures. Often some of the luscious fruits and flowers themselves would be shown starting to spoil or fade. The popularity of vanitas paintings, and of still life generally, soon spread from Holland to Flanders, Spain, and France.

OIL PAINTING Traditional artists' canvas is made from linen, but the less expensive cotton fabric has gained popularity. The artist first prepares a wooden frame called a “stretcher" or "strainer." The difference between the first and second is that stretchers are slightly adjustable, while strainers are rigid and lack adjustable corner notches. The canvas then pulled across the wooden frame and tacked or stapled tightly to the back edge. The next step is for the artist to apply a ground (or size) to isolate the canvas from the acidic qualities of the paint. Traditionally, the canvas was coated with a layer of rabbit skin glue and primed with subsequent layers of finely ground chalk (or marble dust) and rabbit skin glue. Later the process was changed to a sizing of rabbit skin glue with subsequent layers of white priming (gypsum, chalk, barium oxide, titianium(IV) dioxide mixed with linseed oil). Modern gessos are made of titianium dioxide with an acrylic binder and are not "real" gessos in the true sense of the word. The artist might apply several layers of gesso, sanding each smooth after it has dried. Sanding the primed surface is important to roughen the generally slick surface so the subsequent layers of oils will properly adhere. It is possible to tone the gesso to a particular color, but most store-bought gesso is white. The gesso layer will tend to draw the oil paint into the porous surface, depending on the thickness of the gesso layer. Excessive or uneven gesso layers are sometimes visible in the surface of finished paintings as a change in the layer that's not from the paint.
