blinding sunlight. For Théophile Thoré it was the prettiest painting in the world. The piece was commissioned for the new hall of the Kloveniersdoelen, the musketeer branch of the civic militia. Rembrandt departed from convention, which ordered that such genre pieces should be stately and formal, rather a line-up than an action scene. Instead he showed the militia readying themselves to embark on a mission, though the exact nature of the mission or event is a matter of ongoing debate. Contrary to what is often said, the work was hailed as a success from the beginning. Parts of the canvas were cut off (approximately 20% from the left hand side was removed) to make the painting fit its new position when it was moved to Amsterdam town hall in 1715. In 1817 this large painting was moved to the Trippenhuis. Since 1885 the painting is on display at the Rijksmuseum. In 1940 the painting was moved to Kasteel Radboud; in 1941 to a bunker near Heemskerk; in 1942 to St Pietersberg; in June 1945 it was shipped back to Amsterdam. Expert assessments In 1968, the Rembrandt Research Project began under the sponsorship of the Netherlands Organization for the Advancement of Scientific Research; it was initially expected to last a highly optimistic ten years. Art historians teamed up with experts from other fields to reassess the authenticity of works attributed to Rembrandt, using all methods available, including state-of-the-art technical diagnostics, and to compile a complete new catalogue raisonné of his paintings. As a result of their findings, many paintings that were previously attributed to Rembrandt have been removed from their list, although others have been added back. Many of those removed are now thought to be the work of his students. One example of activity is The Polish Rider, now housed in the Frick Collection in New York City. Rembrandt's authorship had been questioned by at least one scholar, Alfred von Wurzbach, at the beginning of the twentieth century but for many decades later most scholars, including the foremost authority writing in English, Julius S. Held, agreed that it was indeed by the master. In the 1980s, however, Dr. Josua Bruyn of the Foundation Rembrandt Research Project cautiously and tentatively attributed the painting to one of Rembrandt's closest and most talented pupils, Willem Drost, about whom little is known. But Bruyn's remained a minority opinion, the suggestion of Drost's authorship is
