Zosimus, New History 2.39

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.

[2.39.1] After Constantine had oppressed and tormented the people in these various modes, he died of a disease, and was succeeded by his three sons, who were not born of Fausta the daughter of Maximianus Herculius, but of another woman, whom he had put to death for adultery. They devoted themselves more to the pleasures of youth than to the service of the state. 

[2.39.2] They began by dividing the nations between them.Constantine the eldest, and Constans the youngest, having for their share all beyond the Alps, together with Italy and Illyricum, the countries bordering on the Euxine Sea and all that belonged to Carthage in Africa; Constantius obtained all Asia, the east, and Egypt. There were likewise others who shared in the government; Dalmatius, whom Constantine made caesar, Constantius his brother, and Hannibalianus, who had all worn robes of purple embroidered with gold, and were promoted to the order of Nobilissimates by Constantine, from respect to their being of his own family.
