Presumably you mean this one? Yes, I hadn't seen it.
I was therefore unaware of your comments on the source of SVA SIDERA NORVNT (although the reference is Aeneid 6.641, not 541).
However, that post doesn't address the question of how:
ties in with the Underworld as described in Aeneid Book 6.Quote
“His own constellations have acknowledged him,” in reference to the Masonic concept of the “Grand Architect,” God.
I'd be interested to know how, in your view, the stars that help to illuminate Virgil's Underworld - a plane imagined as lying beneath the everyday world - have any connection with the "Great Architect"? (BTW, God is generally known to Freemasons in the UK either as either the "Great Architect (of the Universe)" or the "Grand Geometrician" (a 2nd Degree reference), but not usually the "Grand Architect".) The "Aeneid" includes such deities as Jupiter, Venus and Neptune - there is no reference to the God of Judaeo-Christian, or later Masonic, tradition. However, Virgil was a Roman poet, which might explain the presence of a quotation on a medal supposedly prepared in Folkes' honour, given that his antiquarian interests lay in Rome and Italy. Folkes' interest in Rome also explains the presence of the pyramid of Cestius (whose slope, as you yourself tell us, doesn't measure 23.5 deg).
Marvin confesses that he hasn't a clue why the medal includes a sphinx. But he makes no other comment, and doesn't draw any comparison with the Giza Sphinx. The Sphinx on the medal has a crescent moon on its body, but I don't know what the significance of that would be in this context. I don't think that the suggestion that this Sphinx represents the constellations of the Zodiac is all that convincing. Smith's Classical Dictionary, 723, says:
Although why the sculptor would have included a Greek sphinx on a Roman-themed medal, I have no more idea than Marvin ... However, I can find no reference to Folkes having any particular interest in Egypt, so it's difficult to see any connection with the Sphinx at Giza.Quote
Greek Sphinxes ... are not always represented in a lying attitude, but appear in different positions, as it might suit the fancy of the sculptor or poet. Thus they appear with the face of a maiden, the breast, feet, and claws of a lion, the tail of a serpent, and the wings of a bird. Sphinxes were frequently introduced by Greek artists, as ornaments of architectural works.
Your post doesn't provide any references to the source for Folkes' alleged membership of "London Lodge no. 78" or the Lodge in Norwich. Apart from the fact that he was Deputy Grand Master of the Grand Lodge of England in 1724-5 (and, according to Mackey, 314-5, "he held no office afterwards"), I've been unable to find a Masonic source that mentions his membership of any other Lodge (although, of course, this doesn't necessarily mean that he wasn't).
