Self portrait of Godefridus Schalcken (1643-1706)
Johann Wilhelm, Elector Palatine erected impressive buildings such as the Schloss Bensberg and led a lavish court which gave work to many artists and artisans, including the court painters Johannes Spilberg, his daughter Adriana, her later husband Eglon van der Neer, Adriaen van der Werff
Jan Frans van Douven, Herman van der Mijn, Jan van Nickelen, his daughter Jacoba Maria van Nickelen, her husband Willem Troost, Anthoni Schoonjans, Rachel Ruysch, Godfried Schalcken, and Jan Weenix with his daughter Maria Weenix. His enormous collection of paintings by Rubens can still be seen in the Alte Pinakothek in Munich.
His widow Anna Maria Luisa was the last scion of the House of Medici. A patron of the arts, she bequeathed the Medicis’ large art collection, including the contents of the Uffizi, Palazzo Pitti, and the Medicean villas, which she inherited upon the death of her brother Gian Gastone in 1737, and her Palatine treasures to the Tuscan state, on the condition that no part of it could be removed from the capital Florence. Therefore, these treasures are still to be visited in Florence today.
