Definition: Demilune refers to the top of a piece of furniture - usually a small table or commode - shaped like a semi-circle or a half-moon (the words demi lune translate to half-moon in French). Probably developed in France, the style came into widespread use the 1750s, and has remained popular ever since, though it's especially characteristic of Louis XVI and Neoclassical designs, such as Hepplewhite and Sheraton (see photos).
Demilune can also refer to a semi-circular table with a drop-leaf that is flipped up to form a full circle. The flat side allowed the piece to be kept against a wall, to be moved into a room when needed - a typical practice in 18th-century rooms.
