摘要：A complex conservation process revealed the layer of the painting inits original subtlety and delicate retouchings recreated the integralsurface of the painting. As a result, we can confirm that it is a paintingof high artistic quality dating most probably from the middle ofthe 17th century, painted on an oak panel of German origin. Weremain doubtful about the Internet auction suggested authorship,as the painting does not reach the artistic quality of Jan DavidszDé Heem, a top rank artist from the Netherlands. It is possible tocontinue with the art-historical analysis (and other investigations)of the painting, to find further proof for the hypothetical dating andmaybe even reach an attribution but we must not forget to ask thequestions whether and to whom it would be necessary. What matters for the owner of the painting is the fact that an artwork which decorates the wall of his home has both aesthetic and historical value – even without knowing its exact date or the painter.
