He was suffect consul for the nundinium April to June 103 as the colleague of Publius Metilius Nepos, and Urban prefect of Rome.
Ronald Syme argues the date of his praetorship fell in the years 90 to 94.
[2] It is due to the poetry of Martial that we know of two of the offices he did hold: Macer was curator of the Via Appia around the year 95;[3] then governor of Hispania Baetica,[4] which Werner Eck dates to 100/101.
Pliny mentions two occasions where he participated in the proceedings: during the first, which was prior to his consulate, Macer proposed one punishment in the prosecution of Julius Bassus for mismanagement of the province of Bithynia and Pontus;[6] the second regarded money Marcus Egnatius Marcellinus owed to an imperial scribe upon completion of his service as quaestor in an unnamed province.
[7] Macer acceded to the office of urban prefect at an unknown time after his consulship, but definitely before the death of emperor Trajan.
