View of Het Valckhof, Nijmegen
Little is known about the artistâs early artistic activity, and only seven paintings are attributed to him. He appears to have favoured large architectural subjects. Het Valckhof, with its overcast sky and low horizon typifies a particular type of Dutch landscape painting. The name of the castle means âFalcon Courtâ, and it was at this time the most famous in Holland. It was founded as an Imperial Palace by the Emperor Charlemagne (742/3-814 AD).
