Inv. 1221 The Emperor Pertinax, marble, from Antakya, last quarter of the 2nd century AD.

The Wikipedia has: "Pertinax (Latin: Publius Helvius Pertinax Augustus; 1 August 126 – 28 March 193), was Roman Emperor for three months in 193. He is known as the first emperor of the tumultuous Year of the Five Emperors. A high ranking military and Senatorial figure, he tried to restore discipline in the Praetorian Guards, whereupon they rebelled and killed him. Upon his death he was succeeded by Didius Julianus, whose reign was similarly short."
