Judith Leyster (1609-1660) of Haarlem is the most famous female painter of the Dutch Golden Age. In so far as is known, she was the first woman in the Western world to be officially recognised by a painters' guild as a master painter. It gave her the right to have her own workshop, take on pupils and sell her paintings independently. Contemporaries praised her as true 'ley-ster', a leading star in the artistic firmament. And she went far indeed. Leyster is one of the most important Dutch painters of the 1630s. In honour of her 400th birthday, the Frans Hals Museum and the National Gallery of Art in Washington, have jointly organised a small exhibition. Taking centre stage is Leyster's masterful "Self-portrait" (c.1632-1633), in which she presents herself as a spirited painter of portraits and so-called merry companies. Leyster's ambition and exceptional talent are displayed in 11 of her finest works. Throughout the centuries Leyster has been lauded, forgotten, rediscovered and variously interpreted.
