Of course it starts out in another language:

All around town, the maps say
“Tu sei qui.” “You are here.”

In turn logic asks, “Where are the moons?”
And the word problem turns mathematically

On the number of orbs the artist started with
(Scattering them around the city in celebration)

Minus the unrepeated number of moons we’ve seen
(Without ever tripping over these cobbled streets).

Three here in a series of thirty three, more or less,
Depending on how many duplicates I have suppressed.

That leaves me far far short of the total of sixty moons,
One to commemorate each year of the festival’s enlightenment.

Which, according to our guide, could be up at La Rocca
Or, down below, somewhere around the Duomo.

Arriving from base camp by way of the moving stairs,
We stumble onto an exhibit that’s in the open air.

We know Piazza della Signoria well; have seen
In passing the paintings in Galleria poli D’Arte.

But we are surprised now by the outsider pieces and, when
We look back, amazed to find the frescoe we’ve never seen.
