2019 sucks. I'm going back to the Renaissance -- specifically, Florence Italy in the year 1503. I've never been that great a planner, but I should think ahead at least a little.
How do I earn a living in 1503 Florence? Better yet, how do I become rich?
I speak both Latin and modern Italian, so I figure I'll muddle through on the language side. I'm getting pretty fed up with the present, but I can probably spend a couple months learning a new skill if needed. I'm a 19 year old male in pretty good shape.
My crazy great aunt said I'll be the first one to test out her new time machine, and that I'll probably show up naked. She isn't quite sure how it will deal with paradoxes (she isn't exactly filling me with confidence here, but $%#@ the present), so I should do my best to avoid changing anything major. That means things like changing the course of a war or introducing too revolutionary of an invention (though I figure something mundane enough is probably fine) are all out.
Answers will be judged on certainty of outcome (marrying a Medici would be great, but I can't exactly count on that happening) and potential payoff (I could probably get a job as a day laborer, but that wouldn't make me much money).
Unspecific answers are no good. I thought about betting on Palio races, but couldn't dig up any winners from that long ago. If your answer requires knowledge of a specific event, please include resources for me to find that knowledge.
