Short answers, pulled from the story.
Persius was born on the 4th of December 34 AD and died on the 24th of November 62 AD, at the age of twenty-seven. His death from a stomach ailment, recorded in Latin as uitio stomachi, prevented him from completing his book of satires.
Persius was born in Volterra, the ancient Etruscan city known in Latin as Volaterrae, in the province of Pisa. He came from an equestrian family of good standing on both parents' sides.
The Stoic philosopher Lucius Annaeus Cornutus, a close friend and mentor of Persius, took charge of the manuscripts after his death. Cornutus made slight alterations to the satires and then passed them to the lyric poet Caesius Bassus for editing; the collection proved an immediate success on publication.
Persius left six satires, composed in hexameters, along with a short prologue written in scazons. The collection runs to fewer than seven hundred lines in total and was incomplete at the time of his death.
Persius was deeply influenced by Stoicism, primarily through his friendship with the philosopher Lucius Annaeus Cornutus. His satires address Stoic themes including the proper aims of life, self-knowledge, the doctrine of liberty, and the right use of money; ancient critics described him as a preacher of Stoicism rather than a mere satirist of it.
The satires of Persius are difficult because of a dense, compressed style marked by straining of expression, excess of detail, and deliberate obscurity. The source notes this obscurity compares poorly with the clear brevity of Seneca's Epistolae morales, and is not a sign of philosophical depth but of an unrevised and sometimes unfinished text.
