The upper part of the monument is a stone plaque with a long inscription and the portrait of the deceased in a tondo which was painted by a Flemish portraitist, Jacob Ferdinand Voet. There is a painted canopy supported by angels on the wall. The lower part is more interesting: a skeleton is peeping through a window behind an iron grill. The sinister, shrouded figure is facing towards the viewer with his bony hands clutched on his breast. The stone frame of the window is decorated with a coat-of-arms and two bronze medallions. The left one shows a tree with its branches cut but sprouting new shoots and containing a caterpillar spinning its cocoon, while the right one shows the metamorphosis of the caterpillar into a moth. These are the symbols of death and resurrection. The inscriptions convey the same message: "In nidulo meo moriar" ("in my nest I die" i.e. in the city of Rome) and "Ut phoenix multiplicabo dies" ("as a phoenix I multiply my days"). There are two enigmatic inscriptions on the upper and lower part of the monument: "Neque hic vivus" and "Neque illic mortuus" ("Neither living here, nor dead there").
