I also like to imagine people in completely different historical contexts. I never make them actual known historical figures, but I might connect them with someone famous. For example, I often look at my eighteen-year old students as World War I soldiers, or the people sipping wine as Macedonians, or the woman strolling down the street as a Druid priestess (not really sure what that looks like though) or the person who cut me off a French aristocrat (sorry about your impending beheading...)
One of my friends for sure would be a disguised Han warrior, making tea for her family, then sneaking off to fight the Huns. (Or am I thinking of Mulan?) Another friend would have been an early suffragette, and still another, a village chieftain. A professor I know would have been an Abbott, living a scholarly life in a monastery. And so on. I always imagine my husband as a Viking ship-maker or one of Charlemagne's armor-makers. I wouldn't have met him, unfortunately, as I'd have been a servant in some great English manor or maybe teaching in a one-room schoolhouse on the prairie. Or taking bribes as a Chicago gumshoe. Something like that. A girl can dream.
It's fun to speculate what we might have been like 50, 100, 1000, 2000, 10000 years ago! (Cave-man anyone?) Or for that matter, if we lived 5000 years in the future.
What about you? How would you imagine yourself in a different time period?
