This was a brief but very important period in Western European history and culture. The Italian Renaissance is considered to have begun in Florence in approximately 1400. The years from 1500 to about 1530, when painting and sculpture reached a peak of technical mastery and artistic perfection, are often referred to as the High Renaissance. Its influence spread throughout Europe and its influence continued into the 18th century.
