Cornelis de Witt, after Jan de Baen, c. 1670. Like his brother Johan, Cornelis de Witt (1623-1672) was a prominent member of the patrician class. Cornelis was representative of the States General in the field. This meant being present at military engagements on behalf of the government. In 1667, for example, he took part in the raid on Chatham in England. In the background is the English man-of-war, the Royal Charles, which was captured during the raid. Cornelis, who was known for his vanity, is wearing his robe of office.
