Ulpius Marcellus was a Roman Equestrian and member of the gens Ulpia. He was a lawyer from Asia Minor. [1] It is possible he was an advisor to Antoninus Pius and Marcus Aurelius. [2] Marcellus also wrote several books. The jurist Ulpius Marcellus could be the same as the legate Ulpius Marcellus or the governor of Britannia.
He was a lawyer of either freedman or provincial status from Asia Minor. [1] [3] It is possible he was an advisor to Antoninus Pius and Marcus Aurelius. [2] However, the lateness of his time and him not being an advisor to Hadrian indicate that he most likely was not an advisor. Marcellus may also have been a legate and pro-praetor in Pannonia Inferior sometime between 105 and 180 CE. Or the governor of Britannia from 161 to 169 CE. [4] In 158 CE, Ulpius may have become Consul. [5] He wrote at least five books: On the Duties of the Consul, Consultative Opinions, Cervidius Scaevola, and 31 of the Digesta . He also published notes on Julianus's books criticizing some of his innovations.
