Regulus and his colleague, Trio, entered their consulship on the Kalends of October, AD 31, and served until the end of the year. Their magistracy saw the downfall of
Sejanus, the notorious plotter and sycophant of Tiberius, whom Regulus personally conducted to prison. After his consulship, Regulus served as
prefect of the combined provinces of
Macedonia and
Achaea. He was
legatus pro praetore of Achaea from 35 to 44. During his time in Achaea, Regulus and his son were honored with various statues at
Epidaurus and elsewhere. Several Greek aristocrats received Roman citizenship from him and therefore assumed the name Memmius, notably Publius Memmius Pratolaus of
Sparta. After the death of Tiberius, his successor,
Caligula, ordered Regulus to remove the
statue of Jupiter by
Phidias at
Olympia, and bring it to
Rome. He was
proconsular governor of
Asia, possibly for the term 48/49. Regulus was one of the
Sodales Augustales, the
Epulones, and the
Arval Brethren, all important priesthoods.
Tacitus describes him as "a man of dignity, who was a person of influence and good name." Shortly before he died in the year 61, the emperor
Nero described him as one of his nation's greatest resources. ==See also==
