Can you identify the years when these vaguely defined (fictional) events happened?
If the hint isn't clear enough, you can add the roman numerals together and thus find the year.
On Latin inscriptions the year of the event referred to was often expressed through larger letters within the inscription, which were interpreted as Roman numerals and added together.
Absolutely brilliant idea! I'm not great with Roman numerals but I was able to figure out some of the more obvious events and then backtrack from there and figure out what numeral corresponded to what number. It was honestly more fun that way, made it feel more like a puzzle :) Nominated!
