Vermeer was rescued from near-total obscurity in the 19th century, by which time several of his works had been re-attributed to others. However the fact that so many of his works were already in major collections, often attributed to other artists, demonstrates that the quality of individual paintings was recognised even if his collective oeuvre was unknown. Other artists have continued to be rescued from the mass of little known painters: the late and very simple still lifes of Adriaen Coorte in the 1950s, and the landscapists Jacobus Mancaden and Frans Post earlier in the century.
