Art forgery is the creating and selling of works of art which are falsely credited to other, usually more famous artists. Art forgery can be extremely lucrative, but modern dating and analysis techniques have made the identification of forged artwork much simpler.
Art forgery dates back more than two thousand years. Roman sculptors produced copies of Greek sculptures. Presumably the contemporary buyers knew that they were not genuine. During the classical period art was generally created for historical reference, religious inspiration, or simply aesthetic enjoyment. The identity of the artist was often of little importance to the buyer.
During the Renaissance, many painters took on apprentices who studied painting techniques by copying the works and style of the master. As a payment for the training, the master would then sell these works. This practice was generally considered a tribute, not forgery, although some of these copies have later erroneously been attributed to the master.
Following the Renaissance, the increasing prosperity of the middle class created a fierce demand for art. Near the end of the 14th century, Roman statues were unearthed in Italy, intensifying the populace’s interest in antiquities, and leading to a sharp increase in the value of these objects. This upsurge soon extended to contemporary and recently deceased artists. Art had become a commercial commodity, and the monetary value of the artwork came to depend on the identity of the artist. To identify their works, painters began to mark them. These marks later evolved into signatures. As the demand for certain artwork began to exceed the supply, fraudulent marks and signatures began to appear on the open market.
During the 16th century, imitators of Albrecht Dürer's style of printmaking added signatures to them to increase the value of their prints. In his engraving of the Virgin, Dürer added the inscription "Be cursed, plunderers and imitators of the work and talent of others". Even extremely famous artists created forgeries. In 1496, Michelangelo created a sleeping Cupid figure and treated it with acidic earth to cause it to appear ancient. He then sold it to a dealer, Baldassare del Milanese, who in turn sold it to Cardinal Riario of San Giorgio who later learned of the fraud and demanded his money back. However Michelangelo was permitted to keep his share of the money.
