The Memorial Tablet for the Lords of Montfoort is the oldest known surviving painting that was made in the Netherlands.

The lords of Montfoort are shown between Mary and Saint George.

The first three died along with William IV, Count of Holland at the Battle of Warns.

This signifies the fact that he was the only one of the four persons on the painting to have survived the battle.

The painting was originally on the Mary-altar in the St. John's church in Linschoten.
