IOVI PRAE ORBIS -This inscription appears for the first time on a silver coin of
Pescennius Niger, (edited by Vaillant). Septimius Severus, however, immediately afterwards adopted the same dedication in his own coinage. The ancients always believed Juppiter to be Pręses Orbis (the governor of the world), and on this occasion (of contest for the empire between |Pescennius Niger| and |Septimius Severus|) the deity was equally acknowledged by each of the two competitors, when the one refused to yield superiority to the other. -[Eckhel v. vii. 155]
