One of the principal genres (subject types) of Western art. Essentially, the subject matter of a still life painting or sculpture is anything that does not move or is dead. So still life includes all kinds of man-made or natural objects, cut flowers, fruit, vegetables, fish, game, wine and so on. Still life can be a celebration of material pleasures such as food and wine, or often a warning of the ephemerality of these pleasures and of the brevity of human life (see Memento mori). In modern art simple still life arrangements have often been used as a relatively neutral basis for formal experiment, for example by Paul Cézanne and the Cubist painters. Note the plural of still life is still lifes, and the term is not hyphenated.
