Cornelis Norbertus Gysbrechts or Gijsbrechts (ca 1630 - after 1683) was a Flemish painter of still life and trompe-l'œil active in the second half of the seventeenth century.
Trompe l'oeil (deception of the eye)
During his four-year sojourn in Copenhagen Gijsbrechts created an extraordinary series of paintings that aimed to convince spectators that they were facing real, three-dimensional objects rather than flat paintings. The genre is called trompe l’oeil (deception of the eye) and is typical of the Baroque style with its predilection for witty illusionism, metaphor, and allegory. The genre was also popular in the rest of Europe where princes and monarchs used such paintings to amuse diplomats and distinguished guests with their clever deceptions.
