evidence first-rank compositions but uninspired execution are attributed to workshop members or followers. Patronage By the 15th century the reach and influence of the Burgundian princes meant that the Low Countries' merchant and banker classes were in the ascendancy. The early to mid-century saw great rises in international trade and domestic wealth, leading to an enormous increase in the demand for art. Artists from the area attracted patronage from the Baltic coast, the north German and Polish regions, the Iberian Peninsula, Italy and the powerful families of England and Scotland.

The mid-century saw the development of art dealership as a profession; the activity became purely commercially driven, dominated by the mercantile class. Smaller works were not usually produced on commission.

The Burgundian court was seen as the arbiter of taste and their appreciation in turn drove demand for highly luxurious and expensive illuminated manuscripts, gold-edged tapestries and jewel-bordered cups.
