Julianus is the cognomen of a Roman senator whose tenure as suffect consul with one Castus[1] as his colleague, is known from a number of brick stamps.
A number of experts have surmised he is to be identified with a proconsul of Asia mentioned in the writings of the sophist Aelius Aristides.
In 1944, Herbert Bloch noted that bricks produced in Rome between AD 110 and 164 often bore a stamp with the year they were produced in, dated according to the eponymous or ordinary consul of the year, with the exception of four groups of bricks which were dated by the suffect consuls in office for part of that year.
This pair he could state that, based on the form of the stamp, probably held office in a nundinium in the period 127-134[2] Several more examples of bricks stamped with the cognomina of these consuls have since been found.
Further, an inscription from Ephesus, datable to 145, mentions a proconsul [...]lianus, who has been identified with Aristides' Julianus.
