From the ancient Life of Persius we learn that the poet was a cognatus of Arria the Younger, the wife of Thrasea Paetus. Furthermore, we are told that he was pietatis erga matrem et sororem et amitam exemplo sufficientis. As evidence for his piety towards his mother and his sister the biographer mentions that Persius bequeathed his property to them. But we can also find another act of piety towards a relative mentioned in the poet’s biography: a laudatory poem on Arria the Elder. Some considerations about the dates of birth and death of both Arria the Younger and the Elder, Thrasea, and Persius’ father corroborate the assumption that Arria the Elder may have been Persius’ aunt.
