One of the many fruits of national activity in Spain during the age of Ferdinand and Isabella was a new and widespread stimulus to the arts. Until the end of the fifteenth century Spanish art continued to be governed by northern influence which survived, moreover, well into the sixteenth century, when the style chosen for the cathedrals of Salamanca and Segovia was still pure Gothic. A long-standing liking for northern art and an innate taste for Mudejar made Spain slow to adopt the innovations of the Italian Renaissance. The first wave of Italian influence that inspired Plateresque decoration was stimulated by the importation of sculpture and by the arrival of Italian artists in Spain. In painting as in architecture and sculpture the taste for northern art lasted well into the sixteenth century and Queen Isabella's patronage did much to perpetuate it.
