A tondo (plural "tondi" or "tondos") is a Renaissance term for a circular work of art, either a painting or a sculpture. The word derives from the Italian rotondo, "round." The term is usually not used in English for small round paintings, but only those over about 60 cm (two feet) in diameter, thus excluding many round portrait miniatures – for sculpture the threshold is rather lower. A circular or oval relief sculpture is also called a roundel. History Artists have created tondi since Greek antiquity. The circular paintings in the centre of painted vases of that period are known as tondi, and the inside of the broad low winecup called a kylix also lent itself to circular enframed compositions. The style was revived in the fifteenth and sixteenth centuries, particularly in Italy, where it may have developed from the smaller desco da parto or birthing tray. Since then it has been less common. In Ford Madox Brown's painting The Last of England, the ship's wire railing curving round the figures helps enclose the composition within its tondo shape. The background scene is consolidated or omitted, and to a large extent, unimportant. While the background may be visible in tondo paintings, in tondo relief carvings the background is not seen. Andrea della Robbia and other members of his family created glazed terracotta tondi that were often framed in a wreath of fruit and leaves and which were intended for immuring in a stuccoed wall. In Brunelleschi's Hospital of the Innocents, Florence, 1421–24, Andrea della Robbia provided glazed terracotta babes in swaddling clothes in tondos with plain blue backgrounds to be set in the spandrels of the arches. In the sixteenth century the painterly style of istoriato decoration for maiolica wares was applied to large circular dishes (see also charger). The tondo has also been used as a design element in architecture since the Renaissance; it may serve centred in the gable-end of a pediment or under the round-headed arch that was revived in the fifteenth century. Although the earliest true Renaissance, or late Gothic painted tondo is Burgundian, from Champmol (of a Pietá by Jean Malouel of 1400–1415, now in the Louvre), the tondo became fashionable in 15th-century Florence, with Botticelli painting many examples, both Madonnas and narrative scenes. Michelangelo employed the circular tondo for several compositions, both painted and sculpted, including The Holy Family with the infant St. John
