I, too, would like to live in Florence during the height of the Medici rule. The arts in every form were being perfected, and some of greatest thinkers, writers, and creators (artisans) were working their crafts at this time. Florence was the epicenter of everything grand in Europe. I love the city now; I can only imagine loving it more if I had lived in it at the time of the Michelangelo and DaVinci.
I would go back to the time when there were dinosaurs, as long as it was perfectly safe. Dinosaurs terrify and amaze me. I have always been fascinated with how scientists can infer what they look like based on bones and the like. I want to know if they guessed right!
This needs to be moved to the History Discussion Forum - and I'm looking forward to reading the responses!
So many possibilities!! Of course, one of the challenges of this kind of exercise is making the choice, knowing that if you really were able to go back in time, you wouldn't have the benefit of the knowledge you have today about how events were going to play out and what problems would be faced along the way.
Nevertheless, if I had to make a choice of only one general area and time span, I would go to the Boston-Philadelphia corridor in the 1750-1800 time span to witness the interchange of ideas and influences that came together to invent a new country. Maybe I would be a barmaid at one of the taverns frequented by Jefferson, Adams, the Lees, and Franklin. Listening in to the debates and getting involved in the excitement of the revolutionary process would be exhilarating!
I agree that this should move to the History Discussion Forum.
But while it's here, I'll answer:
I'd like to go to Renaissance Italy and France. I'd be an assistant to Leonardo da Vinci, help him with his inventions, pick his brain-- maybe encourage him to finish his work. After a number of years, I'd launch out on my own-- become an adviser to a monarch, teach at the Sorbonne, have conversations with the philosophers, musicians and artists. I'd try my hand at all of their occupations and crafts-- that's what Renaissance men did! Then I'd see if I could sail to the New World to see what I could discover. So many opportunities, so little time. But I'd never be bored.
