Early Netherlandish painting
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. Scholarship of Early Netherlandish painting was one of the main activities of 19th- and 20th-century art history, and a major focus of two of the most important art historians of the 20th century: Max J. Friedländer ("From Van Eyck to Breugel" and "Early Netherlandish Painting") and Erwin Panofsky ("Early Netherlandish Painting").
