In 1671 the family returned for a few months to Amsterdam, but then moved to Flanders and settled in Antwerp.
Cornelis Biltius was in the service of the Oberhofmeister of the Electorate of Trier von Bronsar between 1680 and 1686.
His large-scale canvases were used as wall decorations for castles in Germany such as the Brühl Palaces.
[6] Biltius created mainly trompe l'oeil compositions which are clearly influenced by similar works of his father.
Examples of illusionistic effects in his works are the trompe-l'œil frames, the shade cast by objects on the canvas and the hyperrealist rendering of falling plumes and the dripping of blood of suspended game birds.
