With origins in the Middle Ages and Ancient Greco-Roman art, still-life painting emerged as a distinct genre and professional specialization in Western painting by the late 16th century, and has remained significant since then. One advantage of the still-life artform is that it allows an artist a lot of freedom to experiment with the arrangement of elements within a composition of a painting. Still life, as a particular genre, began with Netherlandish painting of the 16th and 17th centuries, and the English term still life derives from the Dutch word stilleven. Early still-life paintings, particularly before 1700, often contained religious and allegorical symbolism relating to the objects depicted. Later still-life works are produced with a variety of media and technology, such as found objects, photography, computer graphics, as well as video and sound.
