But how would he know how the letters were pronounced?
The conceit seemed to be that he had some kind of Sufficiently Advanced Technology for observation, but one that was somehow lightspeed-limited. They didn't really think it through very well, since it was just an excuse to construct a story about an alien that could be affordably filmed by using props, costumes, and sets left over from historical productions.
A lot of confusion could have been avoided by a slight change in dialogue and by just using a general reference to "centuries in the past" rather than "nine hundred years in the past" or something to that effect.
