This painting of the Nieuwe Kerk, or New Church, in the city of Delft is a real perspectival feat. We are standing in the choir aisle, behind the tomb of William of Orange. We have a wide field of vision: on the left is the nave of the church and on the right the curve of the ambulatory. In order to depict this, Houckgeest used a complex perspectival construction, called ‘diagonal perspective’. He obviously found it difficult, as the black and white tiles on the right are slightly distorted.
