[1][2][3] Vitrasia was the daughter of Annia Fundania Faustina and the Roman Senator Titus Pomponius Proculus Vitrasius Pollio, consul II in 176.
[3] Through her maternal grandfather, Marcus Annius Libo, consul in 128, she was a distant relative to the ruling Nerva–Antonine dynasty of the Roman Empire.
[5] Due to her influence, status and connections, Vitrasia became a public benefactor and a prominent citizen of Cales.
Through her wealth, Vitrasia paid for the construction or repair for the civic Temple of Magna Dea or the Great Mother.
[3] In 182 or 183, she may have been involved in one of numerous conspiracies against her unstable maternal second cousin the Roman Emperor Commodus (who ruled 180–192).
