Hey Sub, we are back from Italy and I am finally able to reliably get online (just switched from cable to DSL and have had mucho problems). A few random impressions...
Rome: We had a really great local guide and probably learned the most from her of any of the local guides on our trip. It turns out if you are with a group with a reservation, you can get into the Vatican museum 30 minutes before it opens to the rest of the public. We were the first ones in and had the place pretty much to ourselves for about 20 minutes. We were able to take our time going through the first three rooms (tapestry room, map room, can't remember what the first room before these 2 was called) before getting to the Sistene chapel, where there were only about 10 people who had gotten there before us. What a truly awe-inspiring spectacle it is. Our guide pointed out to us the difference in size of the various prophets painted along the ceiling. It turns out if you stand at the entrance to the room, they all look the same size, pretty cool. And I guess it was Pope John Paul II who decided that when the Sistene chapel was restored it would be restored to include all the nudity that was later covered up. And St. Peter's basilica was remarkable, what a display of wealth, power, and Christian symbolism.
Florence: We again had a great local guide who took us through the Duomo to see the David. We spent some time studying the "prisoners" and it was really cool to see what those marble statues look like during the creative process. Our guide spent some time talking about Michaelangelo and his life, how he lived to be 89 at a time when average life expectancy for a man was 45, how he had very few friends, never took students, and hated his rival, Leonardo da Vinci. And how he stated that the male physique is more beautiful than the female form. Our guide said it is not known for sure if Michaelangelo was gay, but he said he was extremely religious and probably would not have admitted it to himself or anyone else if he was. I have not read any biographies about Michaelangelo, but after seeing his work, I am definitely going to put that on my to-do list.
We did side-trips to Sienna and San Giamagno (not sure if I spelled that right) and the Tuscan countryside was beautiful.
Venice: It was really, really cold while we were here so that unfortunately detracted from the experience. But we visited the Doge's palace. It was a really interesting system of government they had a there, with the Doge being both a civil servant and a man of great power, and under threat of execution if he abused that power... We also visited the Murano glass factory and witnessed a craftsman in action. Afterwards we toured their gallery and I really, really wish I was independently wealthy so I could afford to buy some of their stuff.

Someday...
I am sorry to say the food was shockingly expensive. I wish we had English pounds to spend because the American dollar is really in the toilet.

My husband has a cousin who lives in Rome and we met her and her husband for dinner. We didn't order much, a plate of spaghetti that we shared, a meat dish each, a plate of grilled veges and a bottle of the house wine. The cousins ordered about the same, and the total bill was almost $250 euro, or nearly $400 with the exchange rate. Really quite shocking... But it was good food.
Overall we had a great time, learned a lot, and had a great cultural experience. We went to Greece a few years ago and it was definitely a great follow-up to visit Italy as well.
