Hadrian banished Favorinus at some point in the 130s, to the island of Chios. Rehabilitated with the ascension of Antoninus Pius in 138, Favorinus returned to Rome, where he resumed his activities as an author and teacher of upper-class pupils. Among his students were Alexander Peloplaton, who would later teach and serve under Marcus Aurelius, and Herodes Atticus, who also taught Marcus Aurelius and to whom Favorinus bequeathed his library. His year of death is unknown, but he appears to have survived into his eighties, and died perhaps around 160 AD.
