The term "quodlibet" is often equated with "trompe-l'oeil". The latter refers to an illusionistic painting that simulates three-dimensionality by means of perspective. The term "quodlibet" is more specific in that it refers to paintings that show an accumulation of disorderly small details. A well-known quodlibet motif is deceptively real-looking writing. Quodlibets also often reproduce lifelike objects hanging on a wooden wall, for example. This is also the case with the present example, which shows a section of a wall panel on which a calendar in a carved wooden frame, sealed letters and folded papers are hung, as well as a writing calendar that was widespread at the time and also known as the "Rosius calendar" after its publisher Jakob Rosius (1598-1676).
