The Madonna of the Yarnwinder is a subject depicted by Leonardo da Vinci. Leonardo was recorded as being at work on one such picture in Florence for Florimond Robertet, a secretary to King Louis XII of France. The subject is known today from several versions of which two, called the Buccleuch Madonna and the Lansdowne Madonna, are thought to be partly by Leonardo's hand. The underdrawings of both paintings show similar experimental changes made to the composition, suggesting that both evolved concurrently in Leonardo's workshop.
