Taurobolium

In the Roman Empire of the second to fourth centuries, taurobolium referred to practices involving the sacrifice of a bull, which after mid-second century became connected with the worship of the Great Mother of the Gods; though not previously limited to her cult, after AD 159 all private taurobolia inscriptions mention the Magna Mater. Originating in Asia Minor, its earliest attested performance in Italy occurred in AD 134, at Puteoli, in honor of Venus Caelestis, as documented by an inscription. The earliest inscriptions, of the second century in Asia Minor, point to a bull chase in which the animal was overcome, linked with a panegyris in honour of a deity or deities, but not an essentially religious ceremony, though a bull was sacrificed and its flesh distributed. The addition of the taurobolium and the institution of an archigallus were innovations in the cult of the Magna Mater made by Antoninus Pius on the occasion of his vicennalia, the twentieth year of his reign, in 158 and 159. The first dated reference to Magna Mater in a taurobolium inscription dates from 160. The vires, or testicles of the bull, were removed from Rome and dedicated at a taurobolium altar at Lugdunum, 27 November 160. Jeremy Rutter makes the suggestion that the bull's testicles substituted for the self-castration of devotees of Cybele, abhorrent to the Roman ethos. Public taurobolia, enlisting the benevolence of the Magna Mater on behalf of the emperor, became common in Italy, as well as in Gaul, Hispania and Africa. The last public taurobolium for which there is an inscription was carried out for Diocletian and Maximian at Mactar in Numidia at the close of the third century. The best-known and most vivid description, though of the quite different taurobolium as it was revived in aristocratic pagan circles, is the notorious one that has coloured early scholarship, which was provided in an anti-pagan poem by the late 4th-century Christian Prudentius in Peristephanon: the priest of the Great Mother, clad in a silk toga worn in the Gabinian cincture, with golden crown and fillets on his head, takes his place in a trench covered by a platform of planks pierced with fine holes, on which a bull, magnificent with flowers and gold, is slain.
