Nicene and Post-Nicene Fathers, Ser. II, Vol I:
The Life of Constantine with Orations of Constantine and Eusebius.: Chapter LIII

Chapter LIII.—Having reigned about Thirty-Two Years, and lived above Sixty, he still had a Sound Body.

He completed the time of his reign in two and thirty years, wanting a few months and days, 3351 and his whole life extended to about twice that period. At this age he still possessed a sound and vigorous body, free from all blemish, and of more than youthful vivacity; a noble mien, and strength equal to any exertion; so that he was able to join in martial exercises, to ride, endure the fatigues of travel, engage in battle, and erect trophies over his conquered enemies, besides gaining those bloodless victories by which he was wont to triumph over those who opposed him. 3352
