The subject of this paper is a base of statue (CIL III 1343) found in 1862 under unknown conditions in the auxiliary camp of Micia and unfortunately lost. Several scholars, among them Th. Mommsen, N. Gostar and I. I. Russu, have dealt with CIL III 1343. The monument was dedicated for the health of the two Augusti, Septimius Severus and Caracalla and of Geta Caesar. The a. thinks that in l. 6 must be read [a]quil[am arg]en[t(eam)]; the dedication was made by the prefect of the ala Campagonum and the vexillations of other units further mentioned found themselves in Micia after returning from the war against Clodius Albinus or before leaving for the Parthian war. This brings us to about the beginning of 198.
