Paintings in old inventories

The number of paintings that Maria van Oosterwijck made, is much higher than the number on this website is included. How many is hard to say. According to Campo Weyerman she worked diligently and quickly, according Houbraken she painted slowly. But if we assume that Maria started to paint professionally from about her 30-year age and she did this thirty years with the low number of about five paintings a year, she must have made still at least 150 paintings. Certainly a number paintings is lost. Many causes are possible: fire, flood or other calamities. Also, aging, improper cleaning or bad repairs in the past will could have been grounds for put a painting of Maria van Oosterwijck at the dirt. Also changing tastes, ignorance of the age, compounded by a misunderstanding of the value, will certainly have contributed that her paintings were seen as a worthless object and eventually disappeared. Doubtless there will be tens of Maria's paintings currently undiscoverd in private hands on the wall or stored in an attic. Still paintings of Maria make appearance whose existence was not known.When you on the link below, a pdf file opens using Acrobat Reader.
