Marble altar found in Rome, in Saint Peter’s Square, a few metres north of the statue of the Apostle, in 1949.

Diis magnis / M(atri) d(eum) m(agnae) I(daeae) / Attidi sancto menotyranno / Alfenius Ceionius Iulianus / Kamenius v(ir) c(larissimus) VII vir epul(onum) / pater et hieroceryx sacr(orum) s(ummi) i(nvicti) / Mitrae hierofanta Haecatae / arch(i)bucolus dei Liberi / aram taurobolio criobolio/que percepto dicabit / die XIIII kal(endis) aug(ustis) d(omino) n(ostro) Gratiano / Aug(usto) III et Equitio cons(ulibus).

19th of July 374 A.D.; cf. CIL VI 499 = Dessau, No. 4147 from the same provenance and of the same date. The exact situation of the Phrygianum in the Vatican city is unknown, but Margherita Guarducci, Cristo e S. Pietro in un documento precostantiniano della Necropoli Vaticana, Roma 1953, 66 holds it to be situated probably “a sinistra dell’odierna gradinata fra l’arco delle Campane e il Camposanto Teutonico”.

Alfenius Ceionius Iulianus Kamenius died in Antium in 395 A.D. (see No. 206). He occurs in the following inscription, which certainly belongs to the same sanctuary. Cf. O. Seeck in RE III col. 1864 No. 31; H. Bloch in HThR XXXVIII, 1945, 211.

CIL VI 499

Diis magnis / M(atri) d(eum) m(agnae) I(daeae) / Attidi sancto menotyranno / Alfenius Ceionius Iulianus / Kamenius v(ir) c(larissimus) VII vir epul(onum) / pater et hieroceryx sacr(orum) s(ummi) i(nvicti) / Mitrae hierofanta Haecatae / arch(i)bucolus dei Liberi / aram taurobolio criobolio/que percepto dicabit / die XIIII kal(endis) aug(ustis) d(omino) n(ostro) Gratiano / Aug(usto) III et Equitio cons(ulibus).
To the Great Gods, to the Great Mother of the Gods of Ida, and to holy Attis Menotyrannus. Alfenius Ceionius Iulianus Kamenius, clarissimus, septemvir epulonum, father and sacred herald of the rites of the supreme invincible Mithras, hierophant of Hecate, archibucolus of the god Liber, after having received the taurobolium and criobolium, dedicates this altar on the 19th of July, during the third consulship of Gratian Augustus and the consulship of Equitius.
