Here we are approaching the historical centre of Firenze.
I have heard an old Italian song, where the river Arno is called “The silver Arno”...
Uhm, rather than silver it seems to be muddy here...
I can very well imagine how terrible it was when Firenze and its inhabitants had to cope with the Arno great flood in 1966, when many people were killed by the fury of the river Arno and thousands of ancient books and art masterpieces were damaged or quite destroyed by water.

While many institutions from around the world financially compensated employees who travelled to Italy and aided in the restoration of Florence, many others volunteered their services for absolutely no pay.

Collectively, these people have been fondly referred to as "Mud Angels," due to their commitment to working in such deplorable conditions.

I was not born yet, but my aunt, Mrs. Violet Bear, has told me many times of that dramatic event, since she went there, as many other people from many different countries, to help to save many precious historical memories from mud.
But this is another story....
