Private collection

A private collection is a privately owned collection of works, usually a collection of art. If seen in a museum alongside a work or describing a work, it signifies that piece of art in a museum is not actually owned by that museum, but is on loan from an independent source, either for the long term or for temporary exhibition. This source will usually be an art collector, although it could be a school, church organization, bank or other company, or any form of institution. Collectors of books, even if they collect for aesthetic reasons (fine bookbindings or illuminated manuscripts for example), are called bibliophiles, and their collections are referred to as libraries.

Art collecting was common among the wealthy in the Ancient World in both Europe and East Asia, and in the Middle Ages, but developed in its modern form during the Renaissance and continues to the present day. The Royal collections of most countries were originally the grandest of private collections but are now mostly in public ownership. However the British Royal Collection remains under the care of the Crown, though distinguished from the private property of the British Royal Family. The cabinet of curiosities was an important mixed form of collection, including art and what we would now call natural history or scientific collections. These were formed by royalty but smaller ones also by merchants and scholars.

The tastes and habits of collectors have played a very important part in determining what art was produced, providing the demand that artists supply. Many types of objects, such as medals, engravings, small plaquettes, modern engraved gems and bronze statuettes were essentially made for the collector's market. By the 18th century all homes of the well-to-do were expected to contain a selection of objects, from paintings to porcelain, that could form part of an art collection, and the collections of those who would normally qualify for the term had to be considerably larger, and some were enormous. Increasingly collectors tended to specialize in one or two types of work, although some, like George Salting (1835-1909), still had a very wide scope for their collections. Apart from antiquities, which were regarded as perhaps the highest form of collecting from the Renaissance until relatively recently, and also books, paintings and prints from the late 15th century onwards, until the 18th century collectors tended to collect fairly new works from Europe. The extension of serious collecting to art from all periods and places was an essentially 19th-century development, or at least dating to the Age of Enlightenment. Trecento paintings were little appreciated until about the 1830s, and Chinese ritual bronzes and jades until perhaps the 1920s. Collecting of African art was rare until after World War II.
