It appears that the earliest version of the Tripura myth ("three-city"; not to be confused with the real state of Tripura), appearing in the Krishna Yajurveda, does NOT have the different "citadels" of the city in different worlds, for example the highest citadel of gold being located in the heavens and the lowest of iron located on earth or in the underworld.

The oldest version also lacks the motif of the three citadels only being able to be destroyed once every 1,000 years, when they all align.

To me, this suggests a kernel of historical narrative which has since taken on a more mythologized and symbolic bent in later versions.

Also note in the post above this one, according to wikipedia, the protection of Mayasura bears striking resemblance to the protection of Noah and other mythological survivors of cataclysms.

We find reference also to the "wealth of the Asuras which is to be won beyond the seven hills"
Which reminded me of a curious reference to "seven metal mountains in the west" in the Book of Enoch, which are to be destroyed along with the fallen angels by a flood.

Likewise, in the earliest version of the Tripura myth in the Krishna Yajurveda, we have Tripura being destroyed by Rudra, and in later versions by Shiva (with help from Vishnu's machinations to turn the Asuras into, basically, atheists, to get Shiva to turn on them). But in neither case is this done alone, there is always a convocation or committee of sorts by the gods (daevas) to discuss and determine how best to vanquish the "evil" city.

We find a parallel in Plato's account of the destruction of the three-ringed city of Atlantis in the Critias dialogue. Zeus calls a meeting of the gods to mete out punishment on the fallen Atlanteans, and this is right where the dialogue is cut off, remaining unfinished. Although, Plato says elsewhere that the island was destroyed by earthquakes and floods some time after their failed war with the proto-Athenians.

Lastly, we see a parallel between Atlantis and Tripura in the concentric, tripartite, metal walled citadels. Tripura having the lowest citadel of iron, the next of silver, then the highest one of gold.

Atlantis is described as having two land rings (which were "some height above the sea") which surrounded a central island. The outermost ring had a wall covered in bronze, the next ring had a wall covered in tin, and then the central island itself had a wall covered in "orichalc gleaming like fire" which surrounded the acropolis, which in turn had within it a sacred shrine surrounded by a golden wall

"By killing the bull-- causing the precession of the equinoxes-- Mithras was in effect moving the entire universe. A god capable of performing such a tremendous deed would be eminently deserving of worship. Furthermore, the ability to move the cosmos would be seen as endowing Mithras with other powers as well, such as the ability to overcome the forces of fate residing in the stars and to guarantee the soul a safe passage through the planetary spheres after death.

Other Mithraic images indicate that Mithras was in fact believed to embody such cosmic power; there are scenes that show Mithras bearing on his shoulder the sphere of the universe or in which a youthful Mithras holds the cosmic sphere in one hand while with his other he rotates the zodiac. In several tauroctonies, the starry sky is shown contained beneath Mithras's cloak.

The status of Mithras as the motive force behind the precession of the equinox could also explain the secretive nature of the Mithraic mysteries. Adherents could well have believed that their knowledge constituted a powerful secret best kept to themselves and among selected initiates. For those chosen, an understanding of the complex astronomical structure underlying the nature of Mithras would have required a lengthy period of indoctrination. Only after acquiring the requisite knowledge could initiates properly appreciate this new god."
