Traditionally Plateresque has been considered a style exclusively "Spanish", a term also applied to architecture in the Spanish territories held by the Spanish Crown between the 15th and 17th centuries. But by the mid-20th century this geographical connotation was questioned under the arguments of several authors, especially Camón Aznar (1945) and Rosenthal (1958), who defined Plateresque generically as a unitary amalgam of elements – Gothic, Muslim, and Renaissance. Aznar does not regard it as a style properly denoted as Renaissance, and Rosenthal emphasizes its association with certain buildings in other European countries, mainly France and Portugal, but also Germany and others.
