Well, not quite. That chapter title is only half of the latin phrase, the whole of which constitutes "the opening lines of an anonymous Latin lyric titled The Vigil of Venus (3rd century A.D.)". The whole phrase goes:

Which also says that it's used as the last line in a book called "The Magus" by one John Fowles. (Honestly no idea who the chap is)
And of course, as these things go, "the English translation" can be as long or short as the skill of the translator makes it; there is no one translation that is exactly right.
Someone's Google-fu let them down on this one, mefears.
This goes beyond a failure of google-fu, surely. Most European languages have about the same information density as Latin so I have no idea where the idea that Latin is particularly concise came from.
I have a weird (to me) affinity for the tropes of Lovecraft horror, but I can't get past the writing. I'd be happy for other recommendations, besides Sloane, of things that touched on the same theme but with tighter writing.
I'm also rather fond of Charlie's novella "A Colder War" - which features items from the Cthulhu mythos as Cold War WMDs - it has a seriously creepy ending.
And Alan Moore did a lovecraftian graphic novel set in the current era called Neonomicon
