Lucius Volusius Maecianus, a lawyer of the mid-2nd cent. ce, probably came from *Ostia, where inscriptions recording his career have been found. He became a libellis (secretary for petitions) to *Antoninus Pius in *Hadrian's reign, and about ce 150 returned as a libellis to Pius, now sole emperor, then became praefectus annonae (prefect of the corn supply) and in 160–2 governor of Egypt. He taught Marcus *Aurelius, even writing a book on fractions and measurements for him, but failed to impress the future emperor. He seems to have written in Greek on the Rhodian sea law; and his fourteen books (libri) on Iudicia publica (‘Serious Crimes’) broke new ground on a scale never later reached, as did his sixteen books on Fideicommissa (somewhat resembling trusts).
