In the poetry of the late Republic and the age of Augustus, a gradual expansion and Romanisation of the role of Magna Mater can be observed. In Catullus, she appears only as a goddess from Asia Minor linked to Attis’ repulsive act. In Lucretius, Cybele is identical with Rhea, which remarkably changes her position as she becomes the mother of all Olympian gods. In Vergil, in addition to being the mother of all gods, she is also the Chief Goddess of the Trojans, who plays an active role in shaping Aeneas’ fate. The most thorough picture of the Goddess is provided by Ovid, who covers every detail of the cult, placing emphasis on embracing the cult. He goes to great lengths to attribute Roman origin to its apparently foreign features, i.e., he tries to Romanise the already embraced cult as much as possible. All this must have taken place under the aegis of and in accordance with Augustus’ religious policy.
