Just imagine you live in Florence and walk to and from work, like most Italians, and travel past these fantastic statues and fountains on nearly every street. It is inspiring.
As a side note, I will say that the statuary in Florence is very different from that of Rome. In Rome, most statues seem to be either religous or of old Roman leaders draped in togas. In Florence, the statues are most clearly related to violence, war, conquering and strength, reflecting its feudal past. There are also more depictions of nude bodies in Florence than in Rome. This is most probably due to the fact that Florence had its hey-day during the Renaissance while Rome is much older.
