Odd, when I posted this using the "right arrow" symbol, it looked like a "right arrow" on my screen.
I edited the post to replace that character with '=', but that just changed the title of the post to an empty string. (Which makes it almost impossible to click on and fix. Once I finally figured out how to fix that, I noticed that the original edit disappeared.)
I was thinking in terms of the application of a mathematical function. So, I might have a function like f(x) = 2x so f(2) = 4 and f(5) = 10. [You can read that as "f of x is 2x and f of 2 is 4 and f of 5 is 10" or as "The application of f to 2 is 4."]
Similarly, if I have a function named 'Jesus' such that the application of that function Jesus(Saul) = Paul, that is, "The application of Jesus to Saul is Paul." [If I remember my long-ago Sunday school lessons, once Saul met Jesus, his name became Paul.]
…N O P Q R S T U V…
So, after meeting his messiah, Saul replaced the first letter of his name by the letter 3 positions earlier in the alphabet.
By analogy, I was thinking that, when the character Raul Endymion met the messiah Aenea, shouldn't his name have changed to "Oaul"?
It was just a weird passing thought.
