Yes, it's the city of Michelangelo, Botticelli, Masaccio

but my favorite is this

 frescoed Angelo annunciante by Jacopo Pontormo,

and you can find it at Chiesa di Santa Felicita, 

in the Cappella Barbadori-Capponi, 

right inside the front door.

For 1€ you can illuminate the tiny chapel

and listen to a veddy british lady

give encyclopedic particulars

often sought by tourists.

But really, just to look is enough.

The Angel floats in space, 

weightless, as an angel should.

It's one of my most very favorite spots

in Florence, and has been since I found it,

years ago.

After you look at the Angel, 

it's nice to sit in one of the pews, and wait; 

 the peaceful presence of ancient, pious souls still fills

the space, it will gather around you and you will sense it;

it can't be otherwise.
