Prime version

In the art world, if an artwork exists in several versions, the one known or believed to be the earliest is called the prime version.^[1] Many artworks produced in media such as painting or carved sculpture which create unique objects are in fact repeated by their artists, often several times. It is regarded as a matter of some importance both by art historians and the art market to establish which version has "priority", that is to say was the original work. The presumption usually is that the prime version is the finest, and perhaps the most carefully done, though some later versions can be argued to improve on the originals.

In many periods the later "repetitions" were often produced by the workshop of the master, with varying degrees of supervision and direct attention from him. This was especially the case with official portraits of monarchs and politicians, which in the Early Modern period were often ordered in large numbers of versions from the court artist as diplomatic gifts. "Prime version" is normally only used when there is another version by the same artist, or his workshop. Other versions by other artists are called copies. Sometimes "reduced versions" that are considerably smaller than the prime one are made. Especially in the case of 19th-century repetitions, the term autograph replica is used of repetitions by the original artist.^[2]
