This is an undated painting by the Dutch inventor and painter Jan van der Heyden of the city of Veere, probably 17th century, from the Mauritshuis Collection. This Collection is not accessible through the website of the Mauritshuis but through euopeana.eu (just search with "mauritshuis" and "painting").
Maurits is the dutch equivalent of Maurice, and in this case it's Maurice "The Brazilian", who made his fortune in Brazil, at a certain time a dutch colony. Maurice also had a carreer in the Dutch Army.
