Roemer with the coats of arms of Maurice and Prince Phillip William

The larger engraved coat of arms belongs to Maurice; next to it is that of Phillip William, the eldest son of William of Orange. Phillip William was taken hostage by the Spanish when he was 13 years old. He was subsequently educated in Spain as a Catholic nobleman. In 1608 he took part, on the side of the Spanish, in the negotiations for the Twelve Years’ Truce: it was the first time that the two half-brothers met each other in person.
