Decorative art of the eighteenth century did not have fixed iconographical references. Indeed the pleasantness of the portrayed subject was more important that the meaning of the painting. For this reason the frescoes that adorn the theatre seem to accompany the viewer who is attending a performance or a meeting. Here two fishermen, obviously ordinary men, amuse themselves by the water. The first one, not yet fishing, seems to be almost a masque, delighted and content. The second man is painted with beautiful and sharp strokes; he has already set his hook.
