In the second half of the 16th century the House of the Blessed, still owned by the Andreasi family, underwent some important changes. In particular, a large room was created on the ground floor, in correspondence to where originally the chamber of the Osanna was located. The room was decorated with frescoes in a late 15th century style, characterized by grotesques divided in sections by statues of cherubs who look like they are holding up the beams of the ceiling. Inside these grotesques we find interesting scenes depicting life in the fields, and the four seasons, which give the name to the room. The frescoes, although they are not of the highest quality, are however very interesting because they portray fantastical figures together with characters from everyday life, sometimes depicted in a theatrical attitude. At the centre of each section, in the lower part, there is always a scene inside a frame that is always different. It may be alluding to a certain month, in line with the overall plan of the room; the attribution however is not always certain, so the play of imagination prevails on the rigid allocation of the parts.
