So you go to Florence, and you make for St. Mark's.
You get to the bottom of the stairs and start to climb.
Lots of other art tourists are around you, so the climbing is slow.
Then at the turn in the stairs you get your first glimpse.
How did you ever manage to paint this annunciation?
You tear up a little.
It's a magic moment.
It's one of those moments in your life
when all around you is the sharp intake of breath.
And then the long sigh.
Let's go and have another look!
