Aurelious Heraclides and and his 'brother' Agathopus, mentioned in a bronze plaque found in Sisak bear a Greek name, which dos not imply that they themselves were of Greek or Eastern origin. Heraclides, a Roman citizen, bears the nomen Aurelius, which became rather common after the Constitutio Antoniniana
of 212 C.E. conferred Roman citizenship on all free men in the empire. However, the possibility cannot be excluded that he, apparently a freedman, might have obtained Roman citizenship before that date.
Other brothers from Siscia
This small bronze tabula ansata was dedicated to Mithras by two brothers, probably not related by blood.
