"The puzzle that Lt. Colonel Cameron Mitchell worked on that was created by Merlin presumably sometime around the lifetime of King Arthur (5th - 6th century) were the Arabic numbers "1 through 8 and their reflections" but this number system did not reach Europe until the 10th century, at the earliest."

Given Merlin is thousands of years old and known to travel between galaxies, I think venturing a bit outside of Europe's comfort zone for a puzzle isn't too far-fetched. The puzzles were also written in Ancient, when did THAT reach Europe in history?
