Late 18th-early 19th century.
Octagonal panel with neoclassical wall decoration.
In the center represented in grisaille a mythological winged figure.
She has a caduceus and a crown in his hands.
The medallion was originally a fresco. Which with the use of a very complex technique was detached from the wall and reapplied on a new canvas and wood panel.
The defects are due to the state of the fresco before it was detached from the wall.
