The city of Bologna, when I was a youngster, was just some place whose namesake got plopped between two slices of Wonder Bread. Two days ago, I was speeding on a train preparing to plop down in Bologna.
The main train station in Bologna was the site of a neo-Nazi bombing in 1980 that killed many people.
I walked for a mile under long protective porticoes down a busy main street.

The handsome medieval center of Bologna, Piazza Maggiore, is commandeered by the world's fifth largest church, the Basilica of San Petronio.
But I wasn't looking for "more old art in old churches," here. Instead, I was headed for the museum of a 20th C. painter who I have admired for almost thirty years, Giorgio Morandi (more about Morandi below). After spending the morning in rapture with Morandi's work, I continued by train on to Padua to take in another great Giotto fresco cycle at the Arena Chapel.
Bizarre is the only way to describe entering the chapel to see the Giottos. The folks at the Arena Chapel had provided, by phone, a 3 o'clock appointment. Tickets were to be picked up one hour before the appointed time, then I had to appear at the entrance exactly five minutes early.
Twenty five people (including myself) were then led into a sealed environmentally controlled room (with hissing StarTrek like doors) for education and decontamination! In exactly fifteen minutes, the interior doors hissed open and we were led into the barrel vaulted chapel to view Giotto's paintings. The doors hissed closed behind us.
In another fifteen minutes, a chime sounded, the doors hissed back open, and we were promptly escorted out. That was it, fifteen minutes decontaminating, fifteen minutes in the chapel. Hardly time to scan the frescoes. Ah, but still, a once in a lifetime event for a painter.
On Morandi:
The signature bleached color in Morandi paintings could be derived directly from the weathered frescoes so prominent and beautiful throughout italy.

The bottles and jars in his paintings have the solidness and stability of a Giotto...
and the contemplative dignity of a Fra Angelico.
At the same time, Morandi was a modernist who absorbed the twentieth century's fetish for flatness and enjoyed the tension between the illusion of space and the hard fact of the picture plane.
Morandi's vision was as steeped in tradition as the city of Bologna, and as modern as a bologna sandwich.
