The interpretation of the Mithraic tauroctony has long been the subject of scholarly debate. The Belgian historian of religions and orientalist Franz Cumont (1868–1947) was the first to propose that the scene should be understood as an astral allegory rather than a purely mythological episode. More recently, David Ulansey developed this hypothesis by interpreting the tauroctony as a symbolic representation of the precession of the equinoxes. In his reading, Mithras—identified with the constellation Perseus—embodies the supreme cosmic power capable of moving the sphere of the fixed stars, while the slaying of the bull symbolises the transition from one cosmic age to another, expressing Mithras' dominion over the celestial order itself.
