Zosimus, New History 1.10
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.
[1.10.1] But not long after Antoninus was remunerated for the murder of his brother, and it was never known who was the person that killed him. The soldiers at Rome then chose for emperor Macrinus, the prefect of the court; while those in the east set up Emisenus,note[Usually called Heliogabalus.] who was related to the mother of Antoninus.
[1.10.2] Each army was now so tenacious of its choice, that a civil disturbance arose between them, and while the supporters of Emisenus Antoninus were bringing him to Rome, those of Macrinus advanced from Italy.note[In fact, Macrinus was in the east.]
[1.10.3] The two armies engaging at Antioch in Syria, Macrinus was so completely routed, that he was compelled to fly from the camp, and was taken and put to death between Byzantium and Chalcedon.
