Zosimus, New History 2.35

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.

[2.35.1] However, I must not omit to relate, that having given to his three sons, Constantine, Constantius, and Constans, the title of caesars, he so greatly enlarged the city of Constantinople, that many of the succeeding emperors, who made it their residence, drew to it too great a number of inhabitants, who flocked there from all parts, as soldiers, merchants, and in other occupations. 

[2.35.2] On this account, its walls were rendered more capacious than those which Constantine built, and the buildings were permitted to be placed so near to each other, that the inhabitants are exposed to much inconvenience and danger both in their houses and in the streets. Besides this a considerable portion of the sea was added to the land by driving down piles, thus forming dry ground, on which was built a sufficient number of houses to form of themselves a considerable city.
