Tomb of Nero (c100). The Sarcophagus of Publio Vibio Mariano is an Ancient Roman marble tomb monument located outdoors along the Via Cassia, a few kilometers outside of the Porta Popola of Rome. For centuries, the sarcophagus has been erroneously touted as the Tomb of Nero referring to the Roman Emperor, perhaps to augment its importance; however, the epigraph clearly states the dedication below. Publio or Publius Vibio Mariano was a Roman soldier and bureaucrat, who ascended through the ladders of military service throughout the empire to tribune. His father, also Publius, was a former pro-consul. He is presumed to have lived during the era of Emperor Septimus Severus, and was born in the province of Julia Dertona. The monument was erected by his daughter, Vibia Maria Maxima. Flanking the epigraph are two young soldiers surrounded by artifacts. While the upper corners are two kneeling angels holding a military cap.On the sides are two eagles capturing a snake, flanking a soldier.
