Quintus Flavius Maesius Egnatius Lollianus signo Mavortius (fl. 330 – 356) was a politician of the Roman Empire. Known as Roman consul Lolliano Mavorzio in the local dialect, an acephalous [headless] statue of Mavortius was discovered in Puteoli, then Pozzuoli (near Naples, Italy) in the C18th. He was Governor of Campania from 328 to 335, comes Orientis from 330 to 336, Proconsul of Africa from 334 to 337, Praefectus urbi of Rome in 342,Consul in 355 and Praetorian prefect of Italy for Constantius II between 355 and 356.
Being a well travelled man who had probably conversed with the scribes of the Serapeum, had made many naked eye observations of the heavens, and taking a strong interest in the subject himself, he encouraged the senatorial writer Julius Firmicus Maternus to write an astrological essay, the Matheseos libri VIII. It is among the last extensive handbooks of a “scientific” astrology that circulated in the West before the appearance of Arabic texts in the 12th century. According to Firmicus Maternus, the system of horoscopic astrology was given early on to an Egyptian pharaoh named Nechepso and his priest Petosiris. The Hermetic texts were also put together during this period.
