The Tauroctony


CIMRM 1400. Tauroctony from Sterzing in
the Tyrol. Colour is modern.

A feature of every Mithraeum was a depiction of Mithras, in the act of killing the bull. This is known as the tauroctony in modern literature.1 These vary in detail, as may be seen by looking at the gallery of images, but the main features may be seen very clearly in the coloured version of CIMRM 1400, right.

The oldest known representative of the tauroctony scene is CIMRM 593 from Rome, 2 a dedication of a certain Alcimus, slave steward/bailiff (servus vilicus) of T. Claudius Livianus, who is identified with T. Iulius Aquilinus Castricius Saturninus Claudius Livianus, the praetorian prefect under Trajan. It dates to the first quarter of the 2nd century. 3

1. Basic structure of the tauroctony

  • Mithras (centre), kneeling on the bull, holding it by the nostrils with his left hand, stabbing it with his right hand, and looking towards us.
  • The bull bleeds. A dog and a snake jump up to lick the blood. A scorpion grabs the bull's testicles.
  • The bull's tail is a sheaf of corn.
  • On either side of the scene are the "torch-bearers", or dadophoroi, Cautes (torch pointing up) and Cautopates (torch pointing down).4
  • All this takes place in a cave, whose roof is above Mithras. Woodland scenes take place above the roof.
  • Top left is the sun, Sol, with a crown of rays. A long ray streaks down to light on Mithras. A raven sits nearby.
  • Top right is the moon, Luna.
  • Side-panels depicting events from the mythological life of Mithras appear on either side. The contents of these vary.5

In some cases busts appear at all four corners, which represent the four winds.

2. Was the taurobolium associated with Mithras?

The taurobolium was an ancient ritual associated with the cult of Cybele in all but five of the inscriptions that record it. In its latest form, recorded by Prudentius, it involved standing in a pit under a metal grill, on which a bull was killed, thereby experiencing a shower of blood.

The literary and epigraphic sources for the taurobolium have been collected by Duthoy.6 None of them make any reference to Mithras. The ritual is associated with the cult of the Great Mother, the Magna Mater, Cybele. Duthoy makes the point that the ritual of a baptism in bull's blood, as described by Prudentius, seems to be a late evolution, probably in competition with Christianity.7

A single inscription from Pesaro associates Mithras with the taurobolium.8 This seems to be a forgery, however.9

There is, therefore, no evidence associating the taurobolium with Mithras.10

The association is widely supposed, probably because it is suggested implicitly in English by Franz Cumont, who suggested that the cults of Cybele and Mithras were associated, and included a discussion of the taurobolium.11 In the complete French text of the TMMM, however, in a footnote not included in his abbreviated version, Les mysteres de Mithra and so not translated in the English, he explicitly rejected the idea that the taurobolium was part of the Mithraic liturgy.12

Online here. p.156: "If we may be reasonably confident that 593 is the earliest extant Roman version of Nithras as bull-slayer (and indeed the earliest such representation anywhere in the west)..."
3Clauss, M., "The Roman cult of Mithras", p.22: "Alcimus was the slave-administrator of one Ti. Claudius Livianus, who is probably to be identified with the praetorian prefect under Trajan, so that the votive is to be dated to the first quarter of the second century AD."; p.146: "A cult-image from Rome, in fact one of the earliest, datable to the first quarter of the second century A.D.(fig. 105), is dedicated, as the inscription tells us, to Sol Mithras (p. 22)." Wikipedia gives a date of 100 AD, and lists a series of references; but Clauss (2000) does not say so, as the Wikipedia reference claims, nor does Beck (1998), so the claim is probably a hoax.

7Duthoy, p.126: "The inscriptions show us that in each of the three phases the taurobolium formed part of the cult of Cybele, although the oldest documents indicate that this was not always so. It seems likely that the taurobolium was taken up into the metroac cult during the reign of Antoninus Pius." And p.27: "However the wide-spread desire for purity in the third century seems sufficient to explain the change to the second phase, and the fierce competition between paganism and Christianity is the obvious reason for the developments characteristic of the third phase."
