The Piazza della Cisterna is shaped almost like a right-angled triangle.

Zooming in three times displays an enlarged view of the sign of a bank, in an old script.

From our viewpoint, the next building along to the right contains a hotel. The sign is to the right of the covered tables.
Note please the position of the sign in relation to the covered tables and the stone structure in the piazza.
That structure might be a well.
Moving to the right by clicking on the Google streetview arrow in fact produces a view that is much nearer to the buildings than that arrow suggests and the display of the sign of the hotel is clearer, though a little distorted in one place.

The script font used in the webspace looks very similar to the script font used on the sign on the building. Are they the same?

Whilst preparing this post I noticed another sign, on the building next along from the hotel.
It has the words ceramiche and carpe diem in unusual lettering.
Translation Plus 10 translates ceramiche from Italian to English as ceramics.
I looked up carpe diem in http://www.google.com and found a link as follows.

Thus, I have learned of a rather nice painting and the interesting story of its discovery in recent times.
