Zosimus, New History 1.09
Zosimus (Greek Ζώσιμος): Early Byzantine, pagan author of a history of the Roman Empire, published in the first quarter of the sixth century CE.
The translation of Zosimus' New History offered here was printed in 1814 by W. Green and T. Chaplin in London, and was probably prepared by J. Davis of the Military Chronicle and Military Classics Office. The translator is anonymous. The text was found at Tertullian.org. The notes were added by Jona Lendering.
[1.9.1] Having adorned many cities with sumptuous edifices, he declared his son Antoninusnote[Caracalla.] emperor, but at his death left his other son Geta co-heir with him in the government, appointing for their guardian Papinianus, a person eminent for his strict justice, and for his ability in the knowledge and interpretation of the law, in which he excelled every Roman either before or since his time.
[1.9.2] But this worthy man in a short time became odious to Antoninus, because he used his utmost endeavours to frustrate a design which he had discovered, formed by Antoninus against his brother Geta. He resolved therefore to remove this obstacle, and concerted with the soldiers the destruction of Papinianus. This being effected, and his hands at liberty, he slew his brother, whom his own mother could not save, though he fled to her for protection.
