I know the Dwemer models of Mundus show it being at the center of everything. The only reason I bring it up is because of a line in the sermons.
"MY DEAF MOONS
SING AND BURN
AND ORBIT ME
I AM OLDER THAN MUSIC
WHAT I BRING IS LIGHT
WHAT I BRING IS A STAR"
Does this imply a heliocentric idea? The Sermons say that Dagoth Ur sleeps at the 'center', Dagoth Ur's head looks like the sun, and here he speaks of how he is being orbited. Sounds like this particular anology if nothing else is done with a heliocentric view in mind.
No, look at the context! This is a sermon about the Hortator killing the Sharmat and removing Vivec, his maker. Not the tourists description of the Aurbis.
Now poem starts with "I AM THE SHARMAT" which refers to everything else said in it. Deaf Moons orbit the Sharmat, the Sharmat will bring a star. And Star roughly means god. The numidium in a simple view or the New Man stuff if you go slightly higher up. The Sharmat is the mythical opponent, Padomay, Sithis, Lorkhan, Dagoth Ur, ect. The moons suggest Lorkhan. Tear down the Pilons, spokes.
