Long attributed to Goya, is now thought to have been painted by the 19th-century forger Eugenic Lucas.

Elements of the painting appear to have been copied from autographed works by Goya, and the painting is therefore classified as a pastiche. Art forgery is the creating and selling of works of art which are falsely credited to other, usually more famous artists.

Among the by-products of these tests are caesium-137 and strontium-90, tiny quantities of which make their way into the Earth’s soil and plants.

It is then via the natural oils, such as linseed from the flax plant, that are used as binding agents in paints that these isotopes end up in post-1945 art.

These isotopes do not occur naturally but are released into the environment by nuclear blasts.

The best place to find such steel was in old pre-WW2 warships.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.
