William III and Mary II by Caspar Netscher, between 1677 and 1684. In 1677 Stadholder William III married his niece Mary Stuart, daughter of the heir to the English throne, later James II. The two portraits form a pair. They were painted by Caspar Netscher, a popular portrait artist in The Hague. Mary is wearing an orange dress; the ermine cloak indicates her royal lineage. In contrast to the homely setting in which Mary is shown, William is depicted with acavalry battle in the background. He is wearing armour and beside him is a helmetwith an orange plume. William is carrying his staff of command. The stadholder was captain general of the army.
