1550: The map of Gielis
1570: The map of Thomas Witteroos
In 1570 Thomas Witteroos makes a map of the Moft, the huge wood on the Hills between Wageningen, Ede and Renkum. The valley of Renkum is at the edge of this map. The north is right (the stream flows from north to south).
1631: The first copy by Nicolaes van Geelkercken
Nicolaes van Geelkercken has drawn two copies of the bottom edge of the map of Thomas Witteroos. His maps form part in a process about the heather fields of Renkum. These maps are just copies without checking in the field whether things had been changed since 61 years.
1635: The second copy
For one reason or another someone made a few years later another copy of the map of Witteroos. For sure this one has not been made by Nicolaes, because it resembles his work not at all.

1657: The map of Isaac van Geelkercken
On the map of Isaac, north is left. Isaac only depicts the northern part of the valley, starting halfway the other maps. It is nowadays the valley between Quadenoord and the Railway. The bends in the stream are nowadays exactly the same: proof that it is an artificial stream, made to supply the Watermill of Quadenoord.
