Granted, it was possible for an organism to live that long on Earth. There were lots of animals that lived for hundreds of years, and some trees were still around that had been there when the Roman Empire was still thriving. He couldn't remember for sure, but he was fairly certain that the oldest known tree was a bit over four thousand years old. And a mistranslation was entirely possible. He thought they’d counted days into weeks and months and years, but he could easily have misunderstood what they were actually counting. Maybe she was part of a dynasty that had ruled for that long. Maybe pony rulers just kept taking the same name as they assumed the throne and that was what counted, not which specific ruler was actually on the throne.
