Really interesting! Somewhat reminds me of the ending of H. P. Lovecraft's "The Rats in the Walls", where the main character, a scion of a very old family which has done some really bad things, goes mad and progressively starts speaking in older and older versions of English after every sentence.
Thanks, that's such a great detail. I was reading Lovecraft during highschool in locally translated print editions. Where such details didn't come through.
Do you know if there any other such language related eastereggs in other of Lovecraft's writing? should I chose to revisit them, in English this time around.
