Persius, in full Aulus Persius Flaccus (/ˈpɜːrʃiəs, ˈpɜːrʃəs/; 4 December 34, in Volterra – 24 November 62), was a Roman poet and satirist of Etruscan origin. In his works, poems and satires, he shows a stoic wisdom and a strong criticism for what he considered to be the stylistic abuses of his poetic contemporaries. His works, which became very popular in the Middle Ages, were published after his death by his friend and mentor, the stoic philosopher Lucius Annaeus Cornutus.
According to the Life contained in the manuscripts, Persius was born into an equestrian family at Volterra (Volaterrae, in Latin), a small Etruscan city in the province of Pisa, of good stock on both parents' side. When six years old he lost his father; his stepfather died a few years later. At the age of twelve Persius came to Rome, where he was taught by Remmius Palaemon and the rhetor Verginius Flavus. During the next four years he developed friendships with the Stoic Lucius Annaeus Cornutus, the lyric poet Caesius Bassus, and the poet Lucan. Lucan would become a generous admirer of all Persius wrote. He also became close friends with Thrasea Paetus, the husband of Arria, a relative of Persius's; over the next ten years Persius and Thrasea Paetus shared many travels together. Later, he met Seneca, but was not impressed by his genius.
