Cornelis Norbertus Gijsbrechts or Gysbrechts was a Flemish painter who was active in the Spanish Netherlands, Germany, Denmark and Sweden in the second half of the seventeenth century. He was a court painter to the Danish royal family. He specialised in trompe-l'œil still lifes, an artistic genre which uses visual tricks to give viewers the illusion that they are not looking at a painting but rather at real three-dimensional objects. He also created many vanitas still lifes.
