Task: Question Generation
Input (English): Passage: Early Netherlandish painting is the work of artists, sometimes known as the Flemish Primitives, active in the Burgundian and Habsburg Netherlands during the 15th- and 16th-century Northern Renaissance, especially in the flourishing cities of Bruges, Ghent, Mechelen, Louvain, Tournai and Brussels, all in present-day Belgium. The period begins approximately with Robert Campin and Jan van Eyck in the 1420s and lasts at least until the death of Gerard David in 1523, although many scholars extend it to the start of the Dutch Revolt in 1566 or 1568 (Max J. Friedländer's acclaimed surveys run through Pieter Bruegel the Elder). Early Netherlandish painting coincides with the Early and High Italian Renaissance but the early period (until about 1500) is seen as an independent artistic evolution, separate from the Renaissance humanism that characterised developments in Italy, although beginning in the 1490s as increasing numbers of Netherlandish and other Northern painters traveled to Italy, Renaissance ideals and painting styles were incorporated into Netherlandish and other Northern painting. As a result, Early Netherlandish painters are often categorised as belonging to both the Northern Renaissance and the Late or International Gothic.
The major Netherlandish painters include Campin, van Eyck, Rogier van der Weyden, Dieric Bouts, Petrus Christus, Hans Memling, Hugo van der Goes and Hieronymus Bosch. These artists made significant advances in natural representation and illusionism, and their work typically features complex iconography.  Their subjects are usually religious scenes or small portraits, with narrative painting or mythological subjects being relatively rare. Landscape is often richly described but relegated as a background detail before the early 16th century. The painted works are generally oil on panel, either as single works or more complex portable or fixed altarpieces in the form of diptychs, triptychs or polyptychs. The period is also noted for its sculpture, tapestries, illuminated manuscripts, stained glass and carved retables.
The first generations of artists were active during the height of Burgundian influence in Europe, when the Low Countries became the political and economic centre of Northern Europe, noted for its crafts and luxury goods. Assisted by the workshop system, panels and a variety of crafts were sold to foreign princes or merchants through private engagement or market stalls. A majority of the works were destroyed during waves of iconoclasm in the 16th and 17th centuries; today only a few thousand examples survive. Early northern art in general was not well regarded from the early 17th to the mid-19th century, and the painters and their works were not well documented until the mid-19th century. Art historians spent almost another century determining attributions, studying iconography, and establishing bare outlines of even the major artists' lives. Attribution of some of the most significant works is still debated.
