'The Sibyl, with frenzied mouth uttering things not to be laughed at, unadorned and unperfumed, yet reaches to a
thousand years (or a millenium) with her voice by aid of the god.' (Heraclitus, fragment 12)
"The Hebrew Sibyl was identified as the author of Sibylline oracles."
"The pseudo-Sibylline texts are a valuable source for information about Classical mythology and early
first millennium Gnostic, Jewish and Christian beliefs."
(quotes from the letter with my rambling thoughts)
"Heretics and others who would doubt them were collectively punished, suspended inverted, exposed outdoors for days or weeks and then ridiculed by audiences" There are some historical references to this type of punishment, some of them in conjunction with crucifiction. There is also "The Hanged Man" of the Tarot, and there is historical/religious reference of this in some pagan religions regarding hanging someone upside down.
The Minoans of Crete had a very technologically advanced society and disappeared. It's now hypothesized that a massive Tsunami took them out.

"A common limning we now understand pictures a grid, filled in with digits in 9 square tiles who sum total is equivalent, judged across or downward" :
8 1 6
3 5 7
4 9 2
dunno what the meaning of it is in the context of the letter, maybe it's the red herring? Although the Sibylline Oracles (and most ancient greek text/prose), was done in hexameter, the numbers all add to 15, which, from a numerology stance, adds up to six (hex)
I agree with the suggestion of Greek Fire being referenced in the letter. The other supposition about WWII, with the "lighting the sky with radiant glows", could tie in with that since Napalm (sometimes referred to as the new 'greek fire') was used during the bombing of Berlin and a few other cities. It's postulated that phospherous was used as an ingredient in the original recipe. In Anne McCaffrey's books, The Dragon Riders of Pern, the dragons eat phospene bearing rock to make the flames.
I think the last paragraph is nothing more than instructions/hints and well-wishes to those who are trying to solve this
Just a few very late night rambling thoughts
