It wouldn't surprise me if someone(s) in this group can come up with whom this refers to:
My Day Closed Is In Immortality.

...and with what this one refers to:
LorD haVe MerCI Vpon Vs.

Let me add that, just reading it like this with no explanation, I wouldn't have had a clue. Hmm--taking a closer look at the second one, I can't figure how it comes out to be what the book says it is...

I suppose I should ask, that if someone sees this post all alone in the thread and knows instantly what the answers are, would you mind holding your post for a bit in case others want to try a few guesses? Thanks.
