Mithraea are built or dug as caves, low and vaulted, often with a star-strewn ceiling, and there is no doubt that this was deliberate. The doctrinal reading of it is another matter. Porphyry, a Neoplatonist writing from outside the cult and long after it was established, reports that the cave was understood as an image of the cosmos and that souls descend and return through gates in the heavens, and he credits part of the account to earlier writers. Roger Beck and others have argued that the astral programme in the iconography, together with the planetary order of the seven grades, supports Porphyry, so that the mithraeum worked as a model of the sky through which the initiate moved. Others hold that Porphyry is reading his own school's cosmology into a cult he never belonged to, and that agreement between a Neoplatonist and a set of images is weak evidence for what Mithraists were actually taught. Both positions are held by working scholars and both can be gone and read.
Facts
Disputed
Status Within the TraditionGenuinely disputed within the tradition 1 Roger Beck's The Religion of the Mithras Cult in the Roman Empire (Oxford University Press, 2006) examines the third century Neoplatonist writer Porphyry's description, in his essay On the Cave of the Nymphs, of the Mithraic cave as a cosmological image of the soul's descent and return through the planetary spheres. Beck's method is source-critical, weighing how much of Porphyry's account reflects genuine Mithraic teaching against how much reflects Porphyry's own Platonist cosmology, since Porphyry wrote roughly two centuries after the cult's spread and was not himself an initiate; some scholars accept his account as preserving real Mithraic doctrine, others hold he is reading his own philosophical system into a rite he observed only from outside. Point in DisputeWhether the cave was taught as an image of the cosmos through which the soul travels. Porphyry reports that it was, and Roger Beck and others hold that the astral programme in the iconography supports him; others hold that Porphyry is reading his own school cosmology into a cult he never belonged to. 1 Status

Seven Grades Mapped Against Seven Planets, the Case for Reading Design
Beck's case for reading the mithraeum as a working model of the cosmos rests on more than the cave shape and the star ceiling, it rests on the order of the seven grades of initiation matching, degree for degree, the order of the seven classical planetary spheres as ancient astronomy arranged them outward from earth. Raven corresponds to Mercury, Bride to Venus, Soldier to Mars, Lion to Jupiter, Persian to the Moon, Sun Runner to the Sun itself, and Father, the highest grade, to Saturn, the outermost and coldest sphere in the ancient scheme. If the correspondence is deliberate, an initiate moving up through the grades was moving, symbolically, up through the planetary spheres toward the fixed stars beyond them, the ascent Porphyry describes souls making through the cave's gates.
Critics of the reading point out that the correspondence survives mainly in a handful of later, non Mithraic sources rather than in an explicit Mithraic text stating it outright, and that reconstructing a lost theology from an assumed astronomical grid risks finding the pattern because it was being looked for. Both sides agree on the archaeology, the caves, the ceilings, the seven named grades themselves, all independently attested. What divides them is how much interpretive weight a silent structure can bear when the initiates who used it left no doctrinal text of their own explaining what it meant to them.

Why this is disputed. No ancient initiate left a written account of Mithraic doctrine, so what the cave and the seven planetary gates meant is reconstructed entirely from silent evidence: the shape of the mithraea themselves, their star patterned ceilings, and outside testimony from writers who were never initiates. Franz Cumont's early twentieth century reading derived the doctrine from Zoroastrian sources and a hypothesized Persian origin. Roger Beck reconstructs it instead from the astronomical program built into the cave's own architecture, largely independent of any single textual source. David Ulansey argues the cult began among first century BCE astrologers responding to the precession of the equinoxes, a genuinely different origin story from either Cumont's or Beck's. None of the three readings can be checked against a Mithraic text, because none survives.
