c. 1640 - 1650. "The Needlewoman" by Diego Velázquez. This is Spanish artist, probably painting in Spain, so so she's not using a naaikussen (Dutch sewing cushion), but it does appear to be a pillow of some sort.
Las Meninas has a very entertaining element about it, and that is the fact that the older man on the far left side is actually the painter of this masterpiece himself, Diego Rodriguez de Silva y Velasquez. He personally inserted himself into this seen to illustrate the importance of him and his paintings... In Velasquez's eyes this act made him of equivalent importance to the subjects he was painting, which in this case was royalty!
