a Roman emperor, known to us only from coins, a specimen of which is annexed. From the number of coins of this emperor found in Austria, Eckhel thinks that the brief reign of Pacatianus was probably in Pannonia or Moesia. The full name of Pacatianus was TI. CL. MAR. PACATINUS. Mar. is variously interpreted, some making it Marius, some Marcius, and others Marinus. Eckhel adopts the last, and assigns the coins to the times of Philippus and Decius (Eckhel, vol. vii. p. 333). There was a Pacatianus, consul A. D. 332, in the reign of Constantine (Fasti).
