Jan van Eyck and Northern Renaissance Art

The Northern Renaissance is the term used to describe the Renaissance in northern Europe, or more broadly in Europe outside Italy. Before 1450 Italian Renaissance humanism had little influence outside Italy. From the late 15th century the ideas spread around Europe. This influenced the German Renaissance, French Renaissance, English Renaissance, Renaissance in the Netherlands, Polish Renaissance and other national and localized movements, each with different characteristics and strengths.

In France, King Francis I imported Italian art, commissioned Italian artists (including Leonardo da Vinci), and built grand palaces at great expense, beginning the French Renaissance. Trade and commerce in cities like Bruges in the 15th century and Antwerp in the 16th increased cultural exchange between Italy and the Low Countries, however in art, and especially architecture, late Gothic influences remained present until the arrival of Baroque even as painters increasingly drew on Italian models.

Universities and the printed book helped spread the spirit of the age spread through France, the Low Countries and the Holy Roman Empire, and then to Scandinavia and finally Britain by the late 16th century. Writers and humanists such as Rabelais, Pierre de Ronsard and Desiderius Erasmus were greatly influenced by the Italian Renaissance model and were part of the same intellectual movement. During the English Renaissance (which overlapped with the Elizabethan era) writers such as William Shakespeare and Christopher Marlowe composed works of lasting influence. The Renaissance was brought to Poland directly from Italy by artists from Florence and the Low Countries, starting the Polish Renaissance.

In some areas the Northern Renaissance was distinct from the Italian Renaissance in its centralization of political power. While Italy and Germany were dominated by independent city-states, parts of central and western Europe began emerging as nation-states. The Northern Renaissance was also closely linked to the Protestant Reformation and the long series of internal and external conflicts between various Protestant groups and the Roman Catholic Church had lasting effects, such as the division of the Netherlands.
